Panax notoginseng, also known as Tianqi, was called "gold does not change" by Li Shizhen, a famous pharmacist in Ming Dynasty. Panax notoginseng is a bright pearl in Chinese medicinal materials. It is recorded in the Qing Dynasty pharmacy book "Compendium of Materia Medica": "Ginseng is the first in nourishing qi, and Sanqi is the first in nourishing blood. The most precious of them.” The well-known Chinese patent medicines “Yunnan Baiyao” and “Pianzihuang” are made from Panax notoginseng as the main raw material. Panax notoginseng belongs to Araliaceae perennial herbaceous plant, because it is excavated three to seven years after sowing and each plant has three petioles, and each petiole has seven leaves, so it is named Sanqi. Its stems, leaves and flowers can be used as medicine. Panax notoginseng is widely distributed in Yunnan, and it is planted almost at an altitude of 1,200 meters and 1,700 meters. Among them, the counties of Wenshan Prefecture are the main production areas. The counties of Yanshan, Maguan, Xichou and other counties of the state have cultivated Panax notoginseng for three times. , Four hundred years of history. Panax notoginseng has the effect of "raw and cooked tonic", that is, taking raw notoginseng can promote blood circulation and remove blood stasis, reduce swelling and relieve pain, and is effective in treating traumatic injuries; taking cooked notoginseng (deep-fried raw notoginseng with chicken oil or other Huang is mature Sanqi), which can nourish blood and strengthen the body. Scientific research and clinical trials have proved that Panax notoginseng, like ginseng, contains nourishing ingredients such as tetracyclic triterpenes, and its content is higher than that of ginseng. The ketone compounds contained in panax notoginseng can promote blood circulation and dilate coronary arteries , reduce the oxygen consumption of the heart, and reduce the workload of the myocardium.
It is very effective to treat chest tightness, angina pectoris and lower cholesterol and blood fat caused by coronary heart disease with Panax notoginseng. The Japanese medical community also believes that Panax notoginseng has the effect of inhibiting cancer. Therefore, the market is very wide, and it is now exported to Southeast Asian countries, Hong Kong, Macao, the United States, Canada, Japan and other countries.
The chemical composition of Panax notoginseng is similar to that of ginseng, mainly containing saponins and flavonoids. A variety of saponins were isolated from the total saponins of Panax notoginseng, mainly panaxadiol and panaxatriol saponins, the total saponin content was as high as 12%, and the monomers included ginsenosides Rb1, Rb2, Rc, Ra, Re, Rf, Nine kinds of Rg1, Rg2, Rh, etc., but does not contain Ro, and other 20 kinds of trace elements such as quercetin, β steroids, peptides and polysaccharides and aluminum, iron, rubidium, strontium. Since the known chemical constituents of Panax notoginseng and ginseng are similar, the pharmacological effects of the two are similar. Unlike ginseng, in addition to the monomer content, it also lacks oleanolic acid.
