Abstract

The invention provides a method for simultaneously preparing gram-grade high-purity tyrosol, renulatin and salidroside from rhodiola crenulata. With rhodiola crenulata as a raw material, the gram-grade high-purity tyrosol, renulatin and salidroside from rhodiola crenulata are prepared from such steps as ethanol extraction, alcohol precipitation, filtration, macroporous adsorption resin separation and silica gel column purification. The method is simple, convenient and quick, and provides a new way of thinking for the mass preparation of the three compounds.

Description

technical field [0001] The invention relates to a preparation method of active ingredients in Rhodiola rosea. Background technique [0002] Rhodiola is the dry root and rhizome of Rhodiola crenulata (Hook.f.et Thoms) H.Ohba, a plant of Crassulaceae. It can replenish qi and activate blood, dredge the meridians and relieve asthma. It is often used for qi deficiency and blood stasis, chest pain and heartache, stroke hemiplegia, fatigue and asthma embolism. Its main chemical components are flavonoids, glycosides and aglycones, organic acids and so on. Among them, salidroside (salidroside) and its aglycone tyrosol (tyrosol) have a wide range of pharmacological effects, and are often used for neuroprotection and cardiovascular protection, and other literature reports have anti-inflammatory, anti-tumor, and immunomodulatory effects . A certain concentration of crenulatin has the effect of anti-apoptosis of rat lung microvascular endothelial cells, and has a bidirectional regulat...
