Problems solved by technology

But at the same time, Panax notoginseng is a traditional Chinese herbal medicine, and the uses of many components have not been developed and utilized.
Notoginseng saponin is its main active ingredient, but according to the metabolism of ginsenoside in the body and its structure-activity relationship, "ginsenoside" is absorbed by the gastrointestinal tract and then metabolized by intestinal bacteria into secondary saponins and glycosides. Absorbed into the blood circulation to play a pharmacological role, indicating that the structure of natural ginsenosides is not the best structure

Abstract

The invention belongs to the technical field of medicines, and discloses a triterpenoid saponins compound, and a preparation method and uses thereof. The triterpenoid saponins compound is 6-O-beta-D-glucopyranosyl-dammara-17beta(H)-20(22)(E)-ene-3beta,6alpha,12beta,24S,25-pentol, and the structure formula is shown in the specification. The chemical structure of the triterpenoid saponins compound is determined by employing mass spectrum and one-dimension and two-dimension nuclear magnetic resonance spectrum technologies and chemical methods. In-vitro antitumor activity tests show that the triterpenoid saponins compound possesses obvious antitumor activity and provides a new source for preparing antitumor medicines.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to triterpene saponins and their preparation methods and uses. Background technique [0002] Panax notoginseng is the dry root and rhizome of Panax notoginseng of the Araliaceae plant. In my country's Yunnan, Guangxi and other places. This product is warm in nature, sweet in taste, slightly bitter, non-toxic. The raw product of Panax notoginseng can reduce swelling and relieve pain, dissipate blood stasis and stop bleeding, and the cooked product can enrich blood and activate blood circulation. Panax notoginseng has a long history of being used to treat diseases, and it is one of the traditional precious medicinal materials commonly used in my country. For thousands of years, it has made great contributions to the prosperity of the Chinese nation, and is deeply concerned and valued by people all over the world. [0003] Nowadays, the rapid development of modern scie...
