Induced extracting method for pigeon pea leaf extract rich in flavone activity component

Abstract

The invention relates to the extraction technology of active ingredients of cajan leaf which is a Chinese herbal medicine, and aims at providing a high-efficiency enzyme inductive extraction method which can economically and quickly obtain a cajan leaf extract rich in five flavonoid active ingredients, namely agnuside, isovitexin, luteolin, apigenin and isorhamnetin. The method is directed against the shortcomings of the traditional extraction method such as long extraction time, high extraction temperature, low extraction efficiency and the like and adopts technologies such as homogenate fragmentation enzymolysis, homothermal enzymolysis, vacuum cavitation extraction, solvent decontamination and enrichment and the like to obtain the cajan leaf extract rich in five flavonoid active ingredients; and the result shows that: the content of the five flavonoid active ingredients contained in the extract can respectively reach 0.223 to 0.296, 0.145 to 0.187, 0.194 to 0.264, 0.108 to 0.150 and 0.074 to 0.102 mg / g, which is 9 percent to 65 percent higher than the content of the five flavonoid active ingredients contained in the extract obtained by the traditional hot reflux method. The method is characterized by high extraction ratio, simple equipment and safe operation, needs no high-temperature heating, is applicable to industrial production and provides a new method and means for the modernization of Chinese traditional medical extraction.

Description

technical field

[0001] The invention relates to a method for efficiently inducing and increasing the content of active ingredients in Chinese herbal medicines and extracting them efficiently, that is, obtaining pigeonpea leaves rich in vitexin, isovitexin, luteolin, apigenin and isorhamnetin Enzyme Induction-Negative Pressure Cavitation Extraction Method for Extracts. Background technique

[0002] Pigeon pea [Cajanus cajan (L.) Millsp.], commonly known as pigeonpea in English, is an annual or perennial tropical or subtropical woody plant, evergreen shrub. Also known as pigeon bean, bean paste tree, tree bean, etc., it is a kind of folk medicine.
