Aristolochic acid is naturally found in Aristolochiaceae plants such as Asarium, Golden Earrings, Du Heng, Aristolochia, Guangfangji, and Horseshoe Incense.
Aristolochiaceae is a commonly used traditional Chinese medicine and an ornamental plant used as a potted plant and trellis plant.
Morphological characteristics of Aristolochiaceae plants:
1. External form:
grassy or woody vines, shrubs or perennial herbs, sparse trees; Roots, stems, and leaves often have oil cells. Simple-leafed, alternate, sessile, leaves entire-marginal or 3-5-lobed, base often heart-shaped, without pedicle.
2. Internal structure:
1) Most of the stem vascular bundles of Aristolochiaceae plants are of the outer toughness type, and the most important feature is that the medullary rays are obvious, the primary rays are wide and long, and the secondary rays are narrow and short, so that the vascular bundles are separated from each other to form a specific shape (Aristolochia structure).
2) hairy hairs on the leaf epidermis are mostly single-columned; The stratum corneum is often granular, the upper or lower epidermis has a mastoid process, and the stomata are infinitive. Calcium oxalate crystals are common and are small square crystals, needle crystals or cluster crystals, and secretory cells are found in stems, leaves, flowers, fruits and seeds.

Aristolochic acid does not exist in food, aristolochic acid is a secondary metabolite of plants, which is found in almost all Aristolochia plants, such as Guangfangji, Qingmuxiang, Tianxian vine, Aristolochia, Xungufeng, cinnabar lotus, etc., which are mostly used in Chinese medicinal materials.
In addition, butterflies that feed on these plants also have aristolochic acid in their bodies. Aristolochic acid is the most common type of aristolochic acid, which is found in almost all Aristolochia plants and often coexists with aristolactams.

1. Guangfangji, Aoki incense, Tianxian vine, Aristolochia, bone-seeking wind, cinnabar lotus.
2. Among the aristolochic acid compounds, the main toxic components are aristolochic acid and aristolochic acid, which are catalyzed by nitroreductase, part of which is reduced to aristolochic lactam, and the other part is further reacted with DNA in the reduction process to form adducts.
3. In the study on the toxicity of aristolochic acid derivatives to porcine renal tubular epithelial cells, it was found that the toxicity of each derivative was related to its chemical structure. Nitro group is the most important toxic group in aristolochic acid derivatives, and the presence of methoxy and hydroxyl groups can further enhance the toxicity of aristolochic acid.
4. Among them, aristolochic acid is the most toxic component of Aristolochia plants. Another study has found that not only aristolochic acid has strong nephrotoxicity, but also its metabolite aristolochlactam.
5. Through the study of the metabolic process and metabolic enzymes of aristolochic acid, it was confirmed that the mutagenicity and carcinogenic toxicity of aristolochic acid are caused by the intermediate product of aristolochic acid nitrogen ions, because it has strong electrophilic ability, which can be combined with the electrophilic group of DNA base extracyclic aminophile to generate corresponding adduct products, so that the RAS gene and p53 gene are mutated, and then induce tumors.

Aristolochic acid causes far more genetic mutations than tobacco and is one of the strongest carcinogens known to cause gene bursts.
In China, there are about 40 kinds of plants containing aristolochic acid, mainly including Tianxian vine (aristolochia stem), Guangfangji (wood defense), aristolochia (fruit), cinnabar lotus, Guan Mutong (Mutong aristolochia), Aokixiang (aristolochia root), Hanzhong Fangji (aristolochia heterophylla), bone-seeking wind (Aristolochia jinmao) and so on.

Answer]: b Bitter almonds, peach kernels, plum kernels, loquat kernels, ginkgo seeds, etc. contain cyanogenic glycosides and cyanogenic acid, which can be hydrolyzed to form hydrocyanic acid. Traditional Chinese medicines that can cause cardiovascular toxicity are:
Drugs containing aconitine such as Chuanwu, Caowu, Aconite, Artemisia Snow, etc.; Drugs containing cardiac glycosides, such as Toad Crisp, Luobu Ma Leaf Withering, Min Zhao Evergreen, Goldenrod oleander, Beiwu Jiapi, etc. Aristolochic acid contained in Mutong (Guanmutong), Aristolochia, Guangfangji, Aokixiang, etc., has the ability to accumulate in the human body, and there is a dose-toxicity dependence on the damage to the kidneys, and the main feature is to cause renal tubular necrosis. Drugs containing aconitine such as Chuanwu, Caowu, Aconite, Artemisia Snow, etc.;
Simba responded that the bird's nest is sugar water, saying that it contains bird's nest acid, but in fact, the bird's nest acid contained in this bird's nest contains only 10,000 bird's nest acid, and the protein content of this bird's nest is zero, which does not meet the standard of "the protein content in bird's nest is about 30%-50%" in the quality regulations of various grades of bird's nest. Therefore, it is not necessarily bird's nest that contains bird's nest acid.
The main components of the basic elements (calcium, sodium, potassium, magnesium) are the four elements necessary for the body's movement and brain activity. All foods contain calcium, sodium, potassium, magnesium and other metal elements in a high amount, and the gray matter finally produced by metabolism in the body is alkaline, this kind of food is called alkaline food. The alkaline foods we commonly use are vegetables, fruits, milk, almonds, chestnuts, coconuts, etc. in hard fruits. >>>More
