Abstract

The invention provides a method for extracting high-purity mogroside V, which comprises the following steps: freezing high-temperature pretreatment, normal temperature and ultra-high pressure extraction, ZTC-II clarifier clarification, 10 micron C 18 Preparative column purification, concentration and drying etc. The invention reduces the damage to the natural active ingredients of mogroside V through freezing high temperature treatment and normal temperature ultra-high pressure treatment, and extracts mogroside V with a purity of up to 99.9%. At the same time, compared with the traditional heating and reflux extraction method, the extraction efficiency is significantly improved and the extraction time is shortened. Time, but also save energy, to achieve continuous large-scale production.

Description

technical field [0001] The invention relates to the field of natural plant extraction, in particular to a method for extracting high-purity mogroside V. Background technique [0002] Luo Han Guo is one of the famous specialties in Guangxi, it is the ripe fruit of the genus Siraitia grosvenorii (Swingle) C. Jeffery of Cucrubitaceae. There are large areas of cultivation in Yongfu, Lingui, Longsheng and other counties in Guangxi, and the yield is considerable. It is one of the main sources of supply for foreign trade of Luo Han Guo. Monk fruit has a long history of medicinal use. In addition to being used as a formula, it is often used as a raw material to produce Chinese patent medicine products. It is one of the traditional Chinese medicinal materials exported in my country. Luo Han Guo contains 16 kinds of essential trace elements and a wide range of elements, rich in vitamin C, vitamin E, essential fatty acids such as linoleic acid, oleic acid, palmitic acid and other esse...
