Problems solved by technology

[0005] Technical problem to be solved: There are many ingredients in conventional Chinese medicines that have antioxidant effects, but their antioxidant effects are weak and cannot effectively remove free radicals. It is necessary to extract and separate the ingredients of traditional Chinese medicines that have antioxidant effects. Carry out rational combination, to improve its antioxidant activity, therefore need a kind of antioxidation compound traditional Chinese medicine extract isolate and preparation method thereof

Abstract

The invention belongs to the field of traditional Chinese medicine, and discloses an antioxidant compound Chinese herbal medicine extract / isolate and a preparation method thereof. The antioxidant compound Chinese herbal medicine extract / isolate consists of the following extracts / isolates in parts by weight: 48 parts of an aqueous extract of herba portulacae, 614 parts of an ethanol extract of chingma abutilon seeds, 25 parts of an ethanol extract of herba houttuyniae and 510 parts of a supercritical extract of semen platycladi. The preparation method of the antioxidant compound Chinese herbal medicine extract / isolate comprises such steps as conducting aqueous extraction, conducting ethanol extraction, conducting supercritical extraction, conducting column separation and the like. The prepared compound Chinese herbal medicine extract / isolate is obvious in effect of scavenging superoxide anion free radicals, and the antioxidant performance of traditional Chinese medicine is enhanced.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and relates to a composite traditional Chinese medicine extraction isolate and a preparation method thereof, in particular to an antioxidant composite traditional Chinese medicine extraction isolation and a preparation method thereof. Background technique [0002] Free radicals are intermediate metabolites of various biochemical reactions in human life activities. They have high chemical activity and are the effective defense system of the body. If they cannot be maintained at a certain level, they will affect the life activities of the body. However, if there are too many free radicals and cannot be removed in time, they will attack the life macromolecules and various organelles in the body, causing various damages to the body at the molecular level, cell level, and tissue and organ level, and accelerate the aging process of the body and induce various diseases. [0003] Superoxide ...
