Method for extracting series effective ingredient of pyracantha

Abstract

The invention discloses an extracting method of effective ingredient of fire fruit series, which comprises the following steps: removing impurity, squeezing after cleaning, immersing to extract through acid low-grade alcohol, filtering, proceeding column chromatographic purifying, drying to obtain red coloring matter, adopting alcohol or acetone to extract fruit residual, filtering, recycling solvent, extracting, purifying, drying to obtain yellow coloring matter, utilizing alcaine to hydrolyze fruit residual, filtering, condensing, decolouring, sedimenting, purifying, drying to obtain pectin, making residuals as raw material of feed.

Description

technical field [0001] The present invention relates to a method for extracting active components of Pyracantha fruit series, specifically a method for sequentially extracting (co-producing) Pyracantha fruit juice, red pigment, yellow pigment, pectin and residual pomace from Pyracantha fruit as feed The method for raw materials belongs to the fields of preparation of food, food and cosmetic additives, active ingredients of natural products, and the like. Background technique [0002] Pyracantha fortuneana (Pyracantha fortuneana) is an evergreen wild shrub fruit tree plant in the genus Pyracantha Roem of the Rosaceae apple subfamily (Maloideae). In the southeast, southwest and northwest provinces of my country, it grows in mountains, hills, shrubs, grasslands and river ditches at an altitude of 500-2800m. Its peel is bright red (a few varieties are golden yellow). my country is extremely rich in Pyracantha resources. For example, Guizhou and Sichuan have an annual output of m...

Problems solved by technology

However, since the 1990s, foreign research has mainly focused on the application of Pyracantha extract (active ingredient) in cosmetics, and has not yet involved research on pigments, pectin, food processing, etc.; domestic research has mainly focused on nutritional ingredients and medicinal ingredient analysis, food rough processing, etc., developed food and health products such as firebuckthorn fruit wine, beverages; but it has not yet involved important aspects such as the purification of red pigment and pectin, and the research and extraction is mainly a single active ingredient ( products), it does not involve the sequential extraction (co-production) of Pyracantha fruit juice, red pigment, yellow pigment, pectin and other active ingredients and the comprehensive utilization of residual pomace as feed raw materials, other important Pyracantha in Pyracantha The active ingredients are wasted in vain, the resource utilization rate is low, and the cost is high; as for the extraction method of the yellow pigment in the pyracantha fruit and the residual pomace as feed, there has been no report so far
