Abstract

The invention provides an extraction and purification method of triterpene acid in seabuckthorns, triterpene acid, triterpenoid saponin and application of the triterpene acid and the triterpenoid saponin and relates to the technical field of extraction and purification. The extraction and purification method of the triterpene acid in the seabuckthorns comprises the following steps of (a) extracting ursolic acid, oleanolic acid and derivatives thereof in seabuckthorn peels with an organic solvent to obtain an extract; (b) treating the extract with an alkali solution firstly, then treating the extract with an acid solution to obtain ursolic acid solid and oleanolic acid solid, and dissolving the ursolic acid solid and the oleanolic acid solid into the organic solvent to obtain a mixed solution; (c) adsorbing the ursolic acid and the oleanolic acid in the mixed solution with macroporous resin, and performing elution and concentration with an eluent after adsorption is finished to obtain acrude product; and (d) adopting HPLC or HSCCC to perform separation on the ursolic acid and the oleanolic acid in the crude product. In the extraction and purification method provided by the invention, the separation effect of the ursolic acid and the oleanolic acid is good, the purity of the ursolic acid reaches up to 97.6 percent or above, and the purity of the oleanolic acid reaches up to 98.2percent or above.

Description

technical field [0001] The invention relates to the technical field of extraction and purification, in particular to a method for extracting and purifying triterpene acids from Hippophae rhamnoides, triterpene acids and triterpene saponins and applications thereof. Background technique [0002] As a local characteristic crop variety, seabuckthorn can prevent and fix sand and bring good economic and sociological value to the local social and economic development. The triterpene acids in seabuckthorn mostly exist in plants in the free state or in the form of glycosides or esters, and are almost insoluble or hardly soluble in water. The triterpene acids in seabuckthorn are mainly ursolic acid and oleanolic acid, which have the functions of protecting the liver, lowering blood sugar and anti-oxidation of the skin. However, the current extraction and purification of ursolic acid and oleanolic acid in seabuckthorn has poor separation effect and low purity. [0003] In view of th...
