Distribution of animal and plant resources: ① Cuscuta chinensis is distributed in most parts of the country. ② Cuscuta chinensis is distributed in most parts of China. Medicinal materials are produced in most parts of the country, mainly in Guangdong. Sichuan and other places.
Collection and storage of medicinal materials: from July to September, when the seeds are ripe, they are cut together with the host, dried in the sun, laid down and dusted off.
Latin name: the original plant of semen cuscutae, cuscuta chinensis lam. or C. Japonica Choi.
Processing method: Semen Cuscutae: removing impurities by washing, and drying in the sun. Tusi cake: Take clean dodder and put it in a pot, add water until it bursts into flowers, and when it becomes brown-gray thick porridge, mash it and make a cake, or add yellow wine and flour to make a cake, cut it into pieces and dry it in the sun. (1) The Theory of Leigong's Baking: "Pick it, remove the thick and thin shells, soak it in bitter wine for two days, percolate it out, soak it in Polygonatum natural juice for one night, until it is bright, and fry it with a small fire. As for it, it is hot in a mortar, and the iron pestle is more than 3,000 yuan into powder. Use the wine and the natural juice of Polygonatum sibiricum to be used relative to Cuscuta chinensis. " (2) Compendium: "Where dodder is used, sand and mud should be washed away with warm water, soaked in wine for one night, exposed to dry and pounded, and if it is not exhausted, it should be soaked and pounded again, and the details should be known in a moment. Another method is to soak the wine for four or five days, steam and expose it for four or five times, grind it into cakes, bake it in the clouds, or dry it. When it is exposed, put several pieces of paper into it and pound it together, and it will immediately become powder, which is labor-saving. "
Textual research: from "Materia Medica from the New": "Semen Cuscutae decoction, slightly fried and broken, if it is a pill, it must be further studied. Because it is difficult to grind people, they are soaked in wine for one night. Boil and spin silk, pound into cakes, dry and grind again, and then it will be fine at the end. However, if the wine is soaked for a long time, it often turns sour and smelly, and it loses all its rushing and fragrant flavor. Every time it is soaked, it is ineffective. In today's market, all the tortoiseshell cakes are filled with wheat flour, and the smell is all good, so it must not be used. " (1) "Bielu": "Dodder, born in Kawasawa field, Korea. Spread over the herbs, the color is yellow and thin, and it is red net, and the color is light and very tired. The month is solid and violent. " (2) Tao Hongjing: "Cuscuta, a lot of fields fall, all floating on Artemisia sphaerocephala. As the old saying goes, there is poria cocos on the bottom and tussah on the top, so it's not necessary today. "
Identification of raw medicinal materials: ① The dried seeds of Cuscuta Cuscuta are oblate or ovoid, and both sides are often depressed, with a long diameter of about 1.5 mm and a short diameter of about 1 mm.. Seed coat is reddish brown or brownish yellow, slightly rough. Observation under the magnifying mirror: there are fine dark dots on the surface, light dots at one end and linear hilum in the center. Hard, not easy to break. Without breath, the taste is slightly astringent. Full particles, no dust and impurities are preferred. Location: Liaoning, Jilin, Hebei, Henan, Shandong, Shanxi, Jiangsu and other places. ② The character of Cuscuta chinensis is similar to that of the previous species, but it is larger, with a long diameter of about 3 mm and a short diameter of about 2 ~ 3 mm. Under the enlarged microscope, there are irregular short-line markings on the surface. Location: Shaanxi, Guizhou, Yunnan, Sichuan and other places. The seeds of the same species, namely, the seashore cocoons, cuscuta maritima mak. and the soybean dodder C. Australia R. Br., are also used as medicine for dodder in a few areas. Microscopic identification: ⑴ Cuscuta australis powder: grayish yellow. (1) The seed coat cells are in slices, yellow-brown, with 2 rows of cells in cross section; The radial direction of exogrid cells is13 ~ 24 μ m, and the tangential direction is 4 ~ 9 μ m, and the wall is thin and lignified; The inner row grid cells are 32 ~ 56 μ m in radial direction and 4 ~ 9 μ m in tangential direction, with thick walls and non-lignified, and the bright zone is located on the upper part of the inner row grid cells. On the surface, the cells are polygonal and slightly shrunk. ② The cross section of epidermal cells in seed skin is square, with a diameter of19 ~ 37 μ m and slightly thickened side walls; The surface is round and polygonal. Endosperm cells containing starch granules and fat oil droplets, cotyledon cells containing fuzzy powder granules and fat oil droplets, and threaded and reticulated vessels can also be seen. ⑵ The radial length of the row grid cells in the seed coat of Cuscuta chinensis is slightly longer than that of the row grid cells. This product is preferably dry, full of seeds and free of impurities.
Chemical composition of traditional Chinese medicine: Cuscuta chinensis contains resin glycoside and sugar. Semen Cuscutae contains glycoside and vitamin A, and its content is 0.0378% calculated by vitamin A. Soybean dodder contains β-carotene, γ-carotene, 5,6-epoxy-α-carotene, Taraxacum taraxanthin and lutein. Semen Cuscutae contains cholesterol, campesterol b- sitosterol, stigmasterol b- coumarin and triterpenoid acids, resin glycosides and sugars, while Semen Cuscutae also contains glycoside and vitamin A. (1) The fruit of Cuscuta australis contains alkaloids. ⑵ Cuscuta seed contains resin-like glycoside, sugar and starch. In addition, it also contains coumarins and steroidal terpenoids, and the flavonoids quercetin, astragaloside, hyperin and quercetin -3-o-β- galactose -7-o- glucoside are obtained.
Chemical identification of traditional Chinese medicine: take a proper amount of this product, soak it in boiling water, and the surface will be sticky. When the seed coat breaks, the yellow-white spiral embryo will be exposed, which is like spinning.
