Abstract

The invention relates to a Lycium ruthenicum Murr. pigment extract and a preparation method thereof. A Lycium ruthenicum Murr. pigment obtained through the preparation method which comprises the steps of cleaning, drying, crushing, extracting, centrifuging, ultra-filtering, purifying and concentrating has the various physiological functions of resisting oxidation, regulating blood fat, protecting vascular endothelial cells, delaying senescence, resisting fatigue, enhancing immune functions and resisting tumors; meanwhile, the preparation method of the Lycium ruthenicum Murr. pigment has the advantages of being simple in technology, easy to operate, higher in yield, good in quality and environmentally friendly.

Description

technical field [0001] The invention relates to the field of plant extracts, in particular to a method for extracting wolfberry black fruit pigment which has various physiological functions such as anti-oxidation, regulating blood lipid, protecting vascular endothelial cells, delaying aging, anti-fatigue, enhancing immune function, and anti-tumor. Background technique [0002] Lycium Ruthenicum Murr is the dry fruit of Lycium Ruthenicum Murr in the family Solanaceae. It is distributed sporadically in Jiuquan, Gansu, eastern Qinghai, central Xinjiang, western Inner Mongolia, Ningxia and Tibet in China. It grows in the barren mountains, riverbeds and beaches where humans cannot survive, and has strong vitality. The wild black black fruit wolfberry in Golmud, Qinghai is known as the "soft gold" of the grassland. However, with the development of nature by human beings, the living space of black wolfberry is getting less and less, creating a rare and precious original ecological ...
