How to distinguish the quality of Ganoderma lucidum, how to distinguish the quality of Ganoderma luc

1) Appearance identification.

Reishi mushroom powder is light brown, tan to purplish-brown. The hyphae are scattered or clumped, colorless or pale brown, elongated, slightly curved, branched. Diameter microns. The spores are brown, ovate, apex flat, colorless on the outer wall, with verrucous protrusions on the inner wall, 8 12 μm long.

2) Test identification.

2 grams of Ganoderma lucidum sample powder was added, 30 ml of ethanol was added, heated and refluxed for 30 minutes, filtered, the filtrate was evaporated, and the residue was dissolved with 2 ml of methanol as a test solution. In addition, 2 grams of Ganoderma lucidum control herbs were taken to make a control herb solution by the same method. Using thin layer chromatography test, absorb 4 microliters of each of the above two solutions, respectively on the same silica gel G thin layer plate, with petroleum ether (60 90) - ethyl formate - formic acid (15 5 1) upper solution as the agent, take out, dry, and place under ultraviolet lamp (365 nm) for inspection.

In the chromatography of the test sample, fluorescent spots of the same color are displayed at the corresponding position of the chromatography of the control medicinal material.

Hello, in recent years, the efficacy of Ganoderma lucidum in the treatment of diseases and health has become more and more well-known.

Ganoderma lucidum is generally known to use red Ganoderma lucidum, which is the highest value of many varieties of Chinese medicine. The quality of Ganoderma lucidum depends on its growth environment, many so-called wild Ganoderma lucidum is not necessarily better than artificially cultivated Ganoderma lucidum, wild Ganoderma lucidum growth environment is relatively poor, insect eyes; There will be a lot of mildew, which will affect the quality of Ganoderma lucidum. On the contrary, the artificially cultivated Ganoderma lucidum is much better in relative condition, and the main thing about artificially cultivated Ganoderma lucidum is to refuse heavy metal pollution, pesticide use and so on.

On the Internet, I see that there is a so-called indoor "indoor pollution-free cultivation" of Ganoderma lucidum worth considering, **Relatively reasonable, as if "**" search [own family Ganoderma monopoly] can be found, there is also a technology and display about his Ganoderma lucidum planting, you can take a look.

Attentively, thank you!

The quality of Ganoderma lucidum strains is directly related to the quality of Ganoderma lucidum products, and the Pharmacopoeia of the People's Republic of China records that the Ganoderma lucidum (red Ganoderma lucidum) strains are of the best quality among all Ganoderma lucidum varieties. According to the different culture mediums, red reishi can be divided into basswood cultivation and bag material cultivation, among which the red reishi cultivated by basswood is the best quality. The red Ganoderma lucidum cultivated by basswood is an old tree with a hard diameter of 20cm because the medium is hard, the medium nutrition is enough for the mycelium of Ganoderma lucidum to survive for two years, the cultivated Ganoderma lucidum cover is large and thick, the cover edge is neat and shiny, the texture is hard, the content of active ingredients is high, and the quality of the Ganoderma lucidum and Ganoderma lucidum spores produced is much better than that of the bag material Ganoderma lucidum, so the basswood red Ganoderma lucidum is a treasure in Ganoderma lucidum.

The choice of Ganoderma lucidum can be judged from its shape, color, thickness and specific gravity. Good Ganoderma lucidum fruiting body has a short stalk and thick flesh, and the back or bottom of the cap can be observed with a magnifying glass, and the tube hole can be seen, which is light yellow or golden yellow is the best, followed by white, and gray-white and the tube hole is larger.

Ganoderma lucidum, also known as Ganoderma lucidum, Shenzhi, mushroom Ganoderma lucidum, wood Ganoderma lucidum, etc., is the dry fruiting body of the polypore fungus Ganoderma lucidum or Zizhi. Ganoderma lucidum, warm in nature, light in taste, return to the heart, lungs, liver, and kidney meridians. It has the effects of nourishing the heart and soothing the nerves, replenishing qi and blood, relieving cough and asthma, enhancing human immunity, delaying aging, regulating blood sugar, and controlling blood pressure.

The cap of genuine Ganoderma lucidum is generally wood-plugged, semicircular, 12 20 cm wide, about two cm thick, the skin shell is hard, initially generally yellow, and then gradually turns reddish-brown, and shiny, with annular ribs and radial wrinkles, the edges are thin and flat, often slightly involuted. The flesh on the lower surface of the cap is white to light brown and consists of numerous tubes; The stipe is lateral, up to 19 cm long, about 4 cm in diameter, reddish-brown or purple-brown, with a lacquer-like luster; There are many spores in the tube. The fruiting body shape of Zizhi is very similar to that of Ganoderma lucidum, the main difference is that the skin shell of the cap and stipe is purple-black or black, and the flesh is rusty brown.

Normally, when we choose Ganoderma lucidum, we can judge the quality of Ganoderma lucidum from its body shape, color, thickness and specific gravity. Good quality Ganoderma lucidum is generally short stalk, thick flesh, the back or bottom of the cap is observed with a magnifying glass, you can see the tube holes, light yellow or golden yellow is often the best, and white is often second, gray-white and the tube hole is larger is the most inferior.

Ganoderma lucidum has been regarded as a symbol of auspiciousness, wealth, beauty and longevity since ancient times, and is known as "fairy grass" and "Ruicao", and traditional Chinese medicine has long regarded it as a precious Chinese herbal medicine that nourishes and strengthens the body.

Folklore has it that Ganoderma lucidum has the effect of resurrecting the dead and immortality. It is well known in the "Compendium of Materia Medica" compiled by Li Shizhen in the Ming Dynasty that Ganoderma lucidum tastes bitter, flat, non-toxic, benefits the heart qi, invigorates the blood, enters the heart and congests the blood, helps the heart and fills the pulse, calms the nerves, benefits the lungs, replenishes the liver qi, replenishes the middle, increases wisdom, good color, improves joints, strengthens muscles and bones, expels phlegm, and strengthens the stomach.

Modern medicine has proved that Ganoderma lucidum contains a variety of physiologically active substances, which can regulate and enhance human immunity, and has a good synergistic effect on neurasthenia, rheumatoid arthritis, coronary heart disease, hypertension, hepatitis, diabetes, tumors, etc. Ganoderma lucidum also has anti-fatigue, beauty and beauty, anti-aging, and sleep aid.

1) Ganoderma lucidum is divided into two types: wild Ganoderma lucidum and cultivated Ganoderma lucidum. Wild reishi lucidum is mostly brownish-black and shiny. Cultivated reishi is a brown body.

2) The choice of Ganoderma lucidum can be judged from its shape, color, thickness and specific gravity. Good Ganoderma lucidum fruiting body has a short stalk and thick flesh, and the back or bottom of the cap can be observed with a magnifying glass, and the tube hole can be seen, which is light yellow or golden yellow is the best, followed by white, and gray-white and the tube hole is larger.

3) Wild Ganoderma lucidum has been eaten by insects when it is young, which will cause many other polypores to be mixed with it, and should be eliminated.

There is confusion between different varieties of Ganoderma lucidum in the market, such as selling cheaper Zizhi as more expensive black lucidum; Artificially cultivated Ganoderma lucidum is relatively uniform in color, shape and size.

1. Regular, cap kidney-shaped, semicircular or nearly round; The lid is yellowish-brown to reddish-brown, the lid edge is pale yellowish-brown, with concentric rings and ring grooves, and longitudinal wrinkles, and the surface is shiny. Wild Ganoderma lucidum grows in the wild in a variety of shapes, because some grow on trees, some grow on the ground, and are made from local materials. Born everywhere, many wild Ganoderma lucidum have branches and leaves on them.

There is also a small grass, if there is soil on the root and fungus, the soil should be very difficult to get rid of, and it is mixed with Ganoderma lucidum (the kind that is easy to get rid of is not counted, it may be artificial).Wild reishi is not uniform in color, different shapes and sizes, no obvious luster on the surface, and there are many scars on the back. The scent is natural.

Wild Ganoderma lucidum absorbs the essence of heaven, earth, sun and moon and grows, and is of course rich in nutrition. Cultivated Ganoderma lucidum cannot be compared with wild Ganoderma lucidum. Supermarkets or pharmacies are placed outside in large barrels in bulk, the color is generally dark brown, and a little shiny, about dozens of yuan, in fact, this kind of Ganoderma lucidum is the residue of the spore powder extracted by the pharmaceutical factory, and it is coated with an antiseptic layer to protect the processed Ganoderma lucidum after it is not bad for a long time, and there is no nutrition.

The taste of the original Ganoderma lucidum is a little astringent and a little sweet and fragrant, and the soup of the Ganoderma lucidum that has been made is a little bitter, there is no taste of Ganoderma lucidum, and of course there is no nutrition, so it is better to buy more meat.

1. Look at the size: If you want Ganoderma lucidum to play a better medicinal property, wild Ganoderma lucidum will be better than artificially cultivated Ganoderma lucidum, wild Ganoderma lucidum picked in the mountains is generally different in size, and it will not be like artificial, batch by batch, and the size will be about the same.

2. Look at the color: wild Ganoderma lucidum is mostly brownish-black and shiny, while cultivated Ganoderma lucidum is a brown entity, although it is also Ganoderma lucidum, but the medicinal properties are much worse, and the color of counterfeit Ganoderma lucidum will be more yellow and have no color.

3. Look at insect eyes: artificially cultivated Ganoderma lucidum is usually strictly controlled and managed by pesticides, and there will be almost no insect eyes.

4. Taste: The taste of wild Ganoderma lucidum is bitter, and it is very bitter, the so-called good medicine is bitter, if it is a fake Ganoderma lucidum, there is basically no taste on the taste.

Look at the color: mainly look at the smoothness. Wild reishi lucidum is mostly brownish-black and shiny.

Artificially cultivated Ganoderma lucidum is a brown body. Because wild purple reishi grows in the wild, it is generally rough, with different shapes and sizes, short legs, and spore powder that has been spit out for more than a year, and it is basically black and gray, so it looks swollen. The artificially cultivated ones are generally more uniform in size, bright and smooth in color, and their legs are straight and slender.

Look at the shape and texture: Ganoderma lucidum ** is generally semicircular, with different shapes and sizes. The natural reishi mushroom has irregular textures, and each one is unique and cannot be replicated.

Due to the artificial control of its growth or acquired processing, in general, the size is the same, the shape is unified, and the texture is mostly relatively regular, without special changes.

Look at the mud feet: Because the real Ganoderma lucidum is wild, it often has mud feet, so we should pay attention to the roots of the Ganoderma lucidum when we choose. The root of the real Ganoderma lucidum has soil, this is because it grows in the mountains, and when it is picked, it is directly uprooted, and there will be some sediment.

Counterfeit Ganoderma lucidum usually has no traces of soil at the roots due to living in an artificially manufactured environment or artificially processed.

Look at the insect eyes: Since the real Ganoderma lucidum is naturally grown, it is inevitable that there will be wild insects, so there will be irregular insect eyes below. However, these insect eyes do not affect the efficacy of Ganoderma lucidum.

Counterfeit Ganoderma lucidum generally does not have these insect moths, because it has been processed the day after tomorrow, so it is basically not bitten by insects.

Smell and smell: Real Ganoderma lucidum has no smell, we feel that it smells when we buy Ganoderma lucidum in the pharmacy, it is caused by the mixing of Chinese medicines and the smell of crossing. The taste of reishi is bitter when eaten, and it is very bitter.

And now some fake Ganoderma lucidum taste a little astringent, not bitter, will smell like an aroma or preservatives, these are Ganoderma lucidum adulterated with other substances, we should be careful when buying.

Look for weeds: Since it grows naturally, there will be weeds or branches on the surface. Fakes, on the other hand, do not have such signs, and most of them are handled relatively cleanly, and no traces left by nature can be seen.

Precautions: 1. Ganoderma lucidum is not a kind of Chinese herbal medicine that can be taken for a long time, if it is a medicinal material for the treatment of diseases, then it is necessary to insist on taking it for more than a month to see better results, if it is only used in daily use of Ganoderma lucidum to delay aging, then it should be stopped after taking it for three consecutive months, and then continue to take it after about three months, so that the effect is the best.

2. Not all people are suitable for taking Ganoderma lucidum soaked in water at any time, for example, users are not able to take Ganoderma lucidum before and after the operation, and users who are bleeding heavily cannot take it, otherwise it will not only not be able to recuperate the body, but it is not conducive to the recovery of the body.

3. Although in principle, anyone can take Ganoderma lucidum, but special attention must be paid when taking it. Under normal circumstances, taking Ganoderma lucidum can effectively improve the body's resistance, and the elderly and children should take it more.

Hope. It is very normal for wild Ganoderma lucidum to have some insect moth, you don't have to be very entangled to buy wild Ganoderma lucidum with insect moth, but you must not eat moldy Ganoderma lucidum, you must carefully select before buying Ganoderma lucidum, and you must not buy it even if it is cheap when you see the wild Ganoderma lucidum with mildew on the surface, and it is very harmful to the body to eat moldy Ganoderma lucidum.

Sniff. Good quality, and relatively fresh wild Ganoderma lucidum smells of a strong mushroom flavor, customers should first use their nose to smell whether the wild Ganoderma lucidum in their hands has a similar fragrance of shiitake mushrooms, wild Ganoderma lucidum with a strong mushroom flavor is generally relatively fresh, and the quality is not poor**.

Ask. China has a vast territory and the distribution of wild Ganoderma lucidum is also very wide, and the quality of wild red Ganoderma lucidum grown in Changbai Mountain area of Jilin Province is slightly better than that of wild Ganoderma lucidum grown in other regional environments. When buying wild reishi, it is best to ask the merchant where the wild reishi comes from before deciding whether it is worth buying.

Cut. At present, there are many health care product stores on the market that claim to sell wild Ganoderma lucidum, but many of them are artificially cultivated Ganoderma lucidum and pretend to be wild Ganoderma lucidum for sale, and some people also like to go to tourist attractions to buy wild Ganoderma lucidum, but the result is that it is worthless artificially cultivated Ganoderma lucidum.

Ganoderma lucidum effect. Ganoderma lucidum is a commonly used traditional Chinese medicine, also known as Sanxiu, Zhizhi and Zhizhi, which is the whole plant of the polypore plant Zizhi or Ganoderma lucidum, which was first published in the "Shennong Materia Medica", with the records of red, black, green, white, yellow and purple six Zhizhi, which is listed as the top grade.

However, according to modern literature and specimens seen, most of the original plants are purple and reishi. Harvested when the fruiting body matures in autumn every year, it can be used as medicine after drying, its nature is flat, sweet in taste, and has the effect of replenishing qi and calming the nerves, relieving cough and asthma, and is used for fatigue, cough, asthma, insomnia, indigestion and other diseases. There are whole plants on the market that have stalk tongues of the same family of plants and pass off as Ganoderma lucidum, and it is necessary to pay attention to identification when using them.
