Embodiment 1

[0044]Embodiment 1: get 5 kg of the above-ground part of Duyiwei as raw material, pulverize it, cross a 20-mesh sieve, add 25000 ml of ethanol with a volume percentage concentration of 70% at 50 ° C, stir and extract for 3 hours, filter, Add 25,000ml of ethanol with a volume percentage concentration of 70% to the dregs (repeatedly extract 3 times), combine the filtrates, concentrate the filtrate under reduced pressure to an extract, then dissolve it with 10,000ml hot water at 60°C, and filter to remove the precipitate after cooling . 4.5kg of the mother liquor has been eluted with ethanol (eluted with 95% ethanol until the ethanol eluent plus distilled water does not appear turbid, and then eluted the column with distilled water until there is no alcohol smell.) Polyamide (14 -30 mesh) column, the loading speed is 10ml / min, the polyamide column is washed with 30000ml of distilled water (flow rate is 10000ml / hour), and the mother liquor and water eluent flowing out from the pol...

Abstract

A process for extracting the iridoid glycoside from common lamiophlomis herb includes reflux extracting in alcohol solution, macroreticular resin adsorpotion, and separation. Said iridoid glycoside can be used as the active staltic component.

Description

technical field [0001] The present invention relates to an extraction process of effective components of Chinese herbal medicines, in particular to a process for extracting total iridoid glycosides from Tibetan medicine unique herb, and at the same time, the invention also relates to the application of the extract as a hemostatic active component. Background technique [0002] Duyiwei is the whole herb or root of Lamiophlomis rotata (Benth.) Kudo, a plant of the genus Lamiophlomis rotata (Benth.) Kudo. It tastes bitter, slightly cold, slightly poisonous, and after a long time in the mouth, it will turn gold like earth, and has a sense of numbness. "Jingzhu Materia Medica" records "solidify the essence and drain yellow water". "Qinghai-Tibet Plateau Drug Illustrated Book" records "replenishing marrow, stopping bleeding, treating edema, yellow water, joint jaundice, and inflammation of spongy bone". [0003] The drug developed with the Tibetan medicine Duyiwei as the main co...
