Abstract

The invention discloses a preparation method of a high purity domestic fungus vitamin D2 extract. According to the preparation method, at early stage, supercritical extraction, saponification, and molecule distillation pre-treatment enrichment are adopted to obtain a domestic fungus ergosterol extract; then pulse high light short time irradiation treatment is adopted, full utilization of the energy of a plurality of ultraviolet rays and other wavelength light of pulse high light is adopted, rapid high efficiency conversion generation of VD2 is realized, and the high purity domestic fungus vitamin D2 extract is obtained. The preparation method is beneficial for development of related medical health care food, special medical food, or dietary supplement, and is capable of promoting value increasing of editable medicinal fungus resources.

Description

technical field [0001] The invention relates to the extraction and separation of ergosterol in edible fungi, and the conversion of high-purity natural vitamin D by pulsed strong light irradiation 2 The preparation process, specifically a high-purity edible fungus vitamin D 2 Extract preparation process. Background technique [0002] Vitamin D (vitamin D, VD) is a group of fat-soluble steroid derivatives, a total of five compounds, including vitamin D 2 (ergocalciferol) and vitamin D 3 (cholecalciferol) two active structures, of which VD 2 It cannot be synthesized in the human body, mainly through the intake of vegetables and dietary supplements. [0003] Vitamin D not only plays an important role in bone diseases (including nutritional rickets, rickets, osteoporosis, etc.). With the deepening of clinical research in recent years, VD also plays a very important role in non-skeletal diseases. Basic research has confirmed that vitamin D receptors (VDR) are widely distribu...
