Problems solved by technology

The purity of the high-purity asparagus saponins prepared by the above method is 82-92%. Although the purity of asparagus saponins is relatively high, the contents of other functional active ingredients such as flavonoids and polyphenols are relatively low, which affects the efficacy of the medicine.

Abstract

The invention relates to an asparagus extract, in particular to the asparagus extract as well as a preparation method and application thereof. The asparagus extract is prepared from the following components in parts by weight: 50-70 parts of saponin, 6-15 parts of polyphenol, 2-5 parts of flavones and 1-2 parts of gamma-aminobutyric acid. The asparagus extract as well as the preparation method andapplication thereof provided by the invention have the advantages that the extracting efficiency is high and the content of effective active ingredients is high; the effects in the aspects of improving atherosclerosis, lipid metabolism disorder, intestinal flora disturbance or apoptosis of aortic smooth muscle caused by air pollutant acrolein are relatively good.

Description

technical field [0001] The invention relates to an asparagus extract, in particular to an asparagus extract and a preparation method and application thereof. Background technique [0002] Acrolein (CH 2 =CH-CHO, acrolein), one of the environmental pollutants, an active α, β unsaturated aldehyde, is a cardiovascular toxic substance derived from the human living environment, and exposure to human-related toxicity acrolein is mainly divided into food sources sexual, environmental and endogenous. Cooking, roasting, frying, and frying in the kitchen can also produce acrolein. It is currently estimated that the daily tolerance of acrolein is 7.5 μg / kg. Acrolein in the environment is one of the by-products of combustion. The combustion of petroleum fuel, biodiesel, plastic, paper, wood, etc. will release a large amount of acrolein. In addition, acrolein is also a highly toxic organic compound in cigarette smoke. Each cigarette can produce about 10-500 μg of acrolein, which is on...
