Abstract

The invention relates to an ultrahigh pressure extraction method of asparagus saponin, and belongs to the technical field of natural products. The process of the ultrahigh pressure extraction method of the asparagus saponin includes the steps of raw material processing, drying and grinding, degreasing, ultrahigh pressure extracting, separating and purifying, and reducing pressure and evaporating to dryness. The step of the ultrahigh pressure extracting is mainly optimized and improved, the ultrahigh pressure extracting technology and the macroporous resin adsorption technology are combined to be applied to the production of the asparagus saponin, the technical problems in the production of the asparagus saponin are solved effectively, the asparagus saponin which is produced has the advantages of being high in safety performance, good in wettability, strong on expansion performance, good in adhesive ability, and the like. Meanwhile, moisture is not easy to adsorb for the asparagus saponin. In addition, extraction time is short, extraction efficiency is high, energy consumption is little, extraction temperature is low, activity of effective constituent is high, and the extraction method is environment-friendly and free of pollution. The asparagus saponin can be effectively extracted from asparagus plants and scraps, and amino acid can also be extracted from the asparagus plants and the scraps.

Description

technical field [0001] The invention relates to an extraction method of active ingredients in plants, more specifically, the invention relates to an ultra-high pressure extraction method of asparagus saponin, which belongs to the technical field of natural products. Background technique [0002] Asparagus, also known as Shi Diaobo, is a perennial herb with rich nutrients and has the effect of both medicine and food. For the utilization of asparagus saponin in asparagus, the traditional method is to take its rhizomes and eat them, but a large amount of asparagus plants and leftovers are discarded, causing great waste and affecting the urban and rural environments. However, scientific research has shown that asparagus plants and leftovers have the same active ingredient content as their roots, so extracting asparagus saponins from asparagus roots, plants and leftovers to make high-purity products can make full use of all the effective ingredients in asparagus. Element. [00...
