Abstract

The invention belongs to the field of pharmacy of traditional Chinese medicines, relating to an extract of effective parts of total saponins in pterocephalus hookeri as well as a preparation method and application thereof. By taking the content of the total saponins in the pterocephalus hookeri as an index, the extract of the total saponins in the pterocephalus hookeri provided by the invention has the characteristics of high content of the total saponins, controllable and stable quality and obvious drug effect. The main component of the extract is oleanane type pentacyclic triterpene saponins, and the content of the total saponins is 50%-90%. The preparation method provided by the invention is economical and simple in extraction technique and is applicable to industrial production. The obtained extract has obvious function of restraining the tumor cell proliferation, and can be applied in preparation of anti-tumor drugs.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine pharmacy, and relates to an extract of effective parts of total saponins of pterygium, a preparation method and application thereof. Background technique [0002] Pteroptera is a commonly used medicinal material in Tibetan medicine, and is widely used in Tibetan medicine preparations, such as Shishierwei Yishou Powder, Jiebai Pills, Erwuwei Ganzi Pills, Erwuwei Donkey Blood Pills, Twenty-six Empas Weiqingpeng Powder, Pomegranate Pu'an Powder, Qingfei Zhike Pill, etc. Tibetan medicine believes that pterygium is cold in nature, bitter in taste, and slightly poisonous. It has the functions of clearing away heat and detoxification, dispelling rheumatism, and relieving pain. It can be used to treat diseases such as blast poison, arthralgia syndrome, dysentery, and arthritis. At present, there are few reports on the research and application of Pterocephalus, and related literatures include: ...
