What are the main components of the root block of Panax notoginseng?

Traditional Chinese medicine refers to Chinese herbal medicines that have been included in drug standards. This kind of medicinal materials have traditional medicinal habits and medicinal parts, but often only one or several parts are selected for medicinal use, and the rest are discarded, which can not make full use of resources. According to the fact that the effective components of drugs can be distributed in different organs of the same plant, traditional Chinese medicine can expand the medicinal parts. For example, Amomum villosum is a traditional Chinese medicine, the main medicinal substance is volatile extract, and the main component of oil is bornyl acetate. Through experiments, the volatile oil 150 ~ 300g can be obtained per 100kg of stems and leaves, and the oil yield is about 0.2%. In autumn management, 500 ~ 700kg of old stems and leaves can be cut every 667m2. At present, the leaf oil of Amomum villosum has been recorded in Chinese Pharmacopoeia, and another Chinese medicine, Notoginseng Radix, is used as a root tuber, and its main components are fatty alkyl series ginsenoside and Notoginseng Radix saponin.

The results showed that the fruits and leaves of Panax notoginseng mainly contained ginsenoside Rb, with the content of 1.20% and 0.7 1% respectively, and the flowers mainly contained ginsenoside RC, with the content of 1.0%. The reed head contains ginsenoside Rb, the content of which is above 5%. So at present, Sanqi Chicken Essence, Sanqi Guanxinning, Sanqi Flower Essence, Sanqi Pollen Oral Liquid, Sanqi Cigarette and Tianqi Toothpaste are all developed from different parts of Sanqi. Another example is ginkgo biloba, a traditional Chinese medicine, which contains flavonoids, stilbenes and phenols. It has pharmacological effects of increasing coronary blood flow, improving cerebrovascular circulation and inhibiting bacteria. In addition to preparing drugs, its extract can also be made into various dosage forms of health food and cosmetics. Hawthorn, a traditional Chinese medicine, is used as medicine by fruit, but the content of flavonoids in hawthorn leaves is 20 ~ 120 times that of hawthorn fruit. Clinical application shows that the effective rate of reducing blood lipid is 88.6%, and it has the function of lowering blood pressure. It is a health drink for patients with coronary heart disease and hyperlipidemia. There are also stems and branches of Uncaria rhynchophylla, aerial parts and fibrous roots of Coptis chinensis and leaves of Eucommia ulmoides Oliv. And the roots of sappan wood.
