Abstract

The invention relates to a drying method of lamiophlomis rotata. The lamiophlomis rotata is prepared through a drying process and a freezing process and is high in contents of main effective ingredients including total saponins and total flavonoid.

Description

field of invention [0001] The invention relates to a medicine preparation method, in particular to a unique drying method, which belongs to the technical field of medicine. Background technique [0002] Duyiwei is the dry aerial part of the plant of the genus Duyizi in the family Lamiaceae. It has the effects of promoting blood circulation to stop bleeding, expelling wind and relieving pain, and is used for bruises, traumatic bleeding, rheumatic arthralgia, yellow water disease and the like. It mainly contains flavonoids, iridoids, saponins and other active ingredients. [0003] Duyiwei is mainly distributed and grown in Gansu, Qinghai, Western Sichuan Plateau, Tibet and other places. The harvest season is August and September every year. Since the growing areas of Duyiwei are mostly economically underdeveloped areas, there is no unified harvesting and processing conditions, and most of the harvesters in various places are local residents, so the post-harvest treatment met...
