Abstract

The process for extracting total flavone from seed of nitraria sibiria includes the following steps: drying seed of nitraria sibiria, pulverizing said dried seed into powder with 20-80 meshes, using ethyl alcohol solution to make reflux extraction at 60-90 deg.c, making the extract pass through non-polar macroporous adsorption resin tower, then using water and 50% ethyl alcohol solution to make elution until the flavoue is net flower out (using FeCl2 solution to make test and detection), collecting eluent, evaporating to recover ethyl alcohol from eluent to obtain flavone solution, concentrating and freeze-drying so as to obtain flavone powder.

Description

technical field

[0001] The invention relates to a process for extracting biologically active flavonoids from wild berry plant resource Nitraria japonica seeds. Background technique

[0002] Nitraria is a typical xeric or super-xeric desert plant of the family Zygophyllceae. It has strong resistance to stress, drought and salinity, and can adapt to high temperature and low cold. Naturally distributed in dry, saline-alkali, windy and harsh habitats with sparse vegetation, it is an excellent shrub for windbreak and sand fixation. Nitraria japonica is a traditional medicinal material of Mongolian, Tibetan, Uighur and other ethnic minorities in the west. It is used for the treatment of various diseases and often appears in Chinese and Tibetan medicine compound prescriptions. According to interviews with farmers and herdsmen in the production area, when the Nitraria fruit is ripe, the masses collect the fresh fruit and swallow it together with the pit. It can treat stomach proble...
