Method for simultaneously extracting multiple effective components from bitter almond

Abstract

The invention discloses a method for simultaneously extracting multiple effective components from bitter almond. The method comprises the following steps of: (1) extracting bitter almond oil: crushing the bitter almond, extracting, and obtaining the bitter almond oil and bitter almond meal; (2) extracting amygdalin: adding alcohol into bitter almond meal for soaking, carrying out insulation under the micro-boiling state, extracting, filtering, obtaining amygdalin extracting solution and filtered slag I, carrying out decompressed concentration on the extracting solution, standing for crystallization, thus obtaining the amygdalin and filtered slag II; (3) extracting bitter-almond total flavones: adding the filtered slag I into the alcohol, carrying out insulation under the micro-boiling state, extracting, filtering, obtaining the total-flavones extracting solution and filtered slag II, concentrating the total-flavones extracting solution to obtain a total-flavones crude product, purifying, thus obtaining the bitter-almond total flavones; and (4) extracting bitter-almond protein: drying the filtered slag II, thus obtaining the bitter-almond protein. The method disclosed by the invention has the advantages that the multiple components can be extracted simultaneously, the resource waste brought by single extraction is avoided and the comprehensive utilization ratio of the bitter almond is increased.

Description

technical field [0001] The invention relates to a method for simultaneously extracting multiple active ingredients from bitter almonds, in particular to a method capable of simultaneously extracting bitter almond oil, amygdalin, total flavonoids of bitter almonds and bitter almond protein. Background technique [0002] Traditional Chinese medicine theory believes that bitter almonds have the effects of lowering qi, relieving cough and asthma, moistening the intestines and laxatives, and are mainly used to treat cough and asthma, chest fullness, phlegm, intestinal dryness and constipation. Pharmacological experiments have confirmed that bitter almonds have the functions of antitussive and asthmatic, anti-tumor, lowering blood fat, laxative and so on. Its components are fatty oils, glycosides, proteins, flavonoids and so on. The fatty oil in bitter almonds is rich in linoleic acid and oleic acid, which have important physiological effects and medicinal value on the human body...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many preparation methods for bitter almond oil, amygdalin, total flavonoids of bitter almond and bitter almond protein, but the existing methods are all to extract a single component from bitter almond, and a single extraction will cause resources. waste, and reduces the comprehensive utilization rate of bitter almonds, and increases the cost of deep processing of bitter almonds
