Abstract

The invention discloses a grape seed extract which consists of the following raw materials in parts by weight: 30-50 parts of grape seeds, 10-16 parts of portulaca grandiflora and 5-9 parts of sweet-clover astragalus. The preparation method comprises the following steps: I. grinding the raw materials according to the proportions in a grinder to 200 meshes for later use; II. adding the grape seeds, portulaca grandiflora and sweet-clover astragalus powder to a supercritical CO2 extractor for extracting, wherein separate temperature is 30-40 DEG C, separate pressure is 9-13MPa, extracting pressure is 20MPa and extracting duration is 3h so as to obtain corresponding volatile oil and liposoluble constituents; III. dipping medicine residue to 10 times of 80% of ethanol at room temperature for 20h after removing the volatile oil and liposoluble constituents, filtering and collecting medicine liquid; then dipping the medicine liquid in 10 times of 80% of ethanol at room temperature for 20h once again and filtering; such repeating for three times; and IV. combining the medicine liquid obtained from the step III and the medicine liquid obtained from the step IV, decompressing and concentrating, recovering ethanol and spray-drying so as to obtain solid dry powder. The grape seed extract disclosed by the invention has a significant curative effect on female irregular menstruation.

Description

technical field [0001] The invention relates to the field of health products, in particular to a grape seed extract and a preparation method thereof. Background technique [0002] As we all know, grape seed extract is rich in grape seed extract proanthocyanidins (OPC), OPC is a highly efficient free radical scavenger. Its anti-free radical oxidation function is 50 times that of vitamin E and 20 times that of vitamin C. It can remove toxic free radicals in the human body, protect human cells and tissues from oxidative damage by free radicals, and prevent more than 80 free radical-related diseases such as allergies, cancer, and aging. It is based on the effect of grape seeds that Europeans call grape seeds a natural cosmetic in the body, which can restore the vitality of collagen and make the skin smooth and elastic. Grape seed is also a natural sunscreen, which can prevent ultraviolet rays from damaging the skin. Followed by health benefits. The ratio of high-density chol...
