Abstract

The invention discloses a lycium ruthenicum stock solution and a preparation method thereof. The preparation method comprises the following steps: placing dried lycium ruthenicum in a jet mill to perform ultrafine pulverization, and grinding the lycium ruthenicum through liquid nitrogen to obtain ultrafine powder; adding a cellulase solution into the ultrafine powder for ultrasonic assisted extraction to obtain a first extracting solution; filtering the first extracting solution to obtain first filtrate and first filter residues, and adding a pectinase solution into the first filter residues for ultrasonic assisted extraction to obtain a second extracting solution; filtering the second extracting solution to obtain second filtrate and second filter residues, and adding ethanol to perform microwave assisted extraction to obtain a third extracting solution; mixing the first filtrate, the second filtrate and the third extracting solution, carrying out ultrasonic extraction with ethanol asan extracting solution, and finally performing centrifugation to remove the ethanol. The lycium ruthenicum stock solution and the preparation method thereof have the advantages that damage to activeingredients is avoided in the preparation process of the lycium ruthenicum stock solution, the stock solution contains most of the active ingredients in the lycium ruthenicum, and especially, the content of anthocyanin is effectively increased.

Description

technical field [0001] The technical field of wolfberry processing of the present invention particularly relates to a black wolfberry stock solution and a preparation method thereof. Background technique [0002] Black wolfberry (Lycium ruthenicum Murr) is a perennial salt-tolerant and drought-resistant plant of the Lycium genus in the Solanaceae family. Its edible and medicinal parts are its dried fruits. According to "Flora of my country", it is distributed in the Loess Plateau in the northwest of Shaanxi, Ningxia, Gansu, Qinghai, Inner Mongolia, Xinjiang and Tibet. Black wolfberry is a medicinal material with unique nutritional value and medical value, and it is also an important economic and ecological crop. As a well-known Chinese herbal medicine, black wolfberry is used to treat heart disease, irregular menstruation, menopausal diseases, etc. Anthocyanin is a kind of polyphenol flavonoid anthocyanin, which is an important active substance in black wolfberry and has u...
