Extraction method of Chinese wampee leaf active ingredients and applications thereof in preparation of skin care cream

Abstract

The invention discloses an extraction method of Chinese wampee leaf active ingredients and applications thereof in preparation of a skin care cream. Cellulase and compound protease are applied to loosen and break plant cell walls, reduce mass transfer resistance and accelerate the release of active ingredients, namely flavonoid substances and polyphenols; the slightly alkaline small-molecular water is used for extracting the residual active ingredient from Chinese wampee leaves; the Chinese wampee leaf extract prepared by utilizing the modern bioengineering technology of micro-filtering membrane purification extracting liquid and the like is rich in antioxidant ingredients and antibacterial and anti-inflammatory ingredients of polyphenols, flavones and the like, and the extraction and separation yield is high; and the Chinese wampee leaf active ingredients can be used for preparing skin care cream.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from plants, in particular to a method for extracting active ingredients from wampum leaves and its application for preparing skin cream. Background technique [0002] Huangpi, [Latin scientific name] Clausena lansium (Lour.) Skeels [Also known as] yellow bullet, yellow marble, yellow section; Rutaceae, small tree, up to 12 meters high. The leaflets are ovate or ovate-elliptic, asymmetrical on both sides, and the panicles are terminal; the buds are spherical, the calyx lobes are broadly ovate, the petals are oblong, the filaments are linear, the fruit is light yellow to dark yellow, the flesh is milky white, translucent , 1-4 seeds; flowering in April-May, fruiting in July-August. Yellow skin is native to southern China and has a history of more than 1,500 years in China. The flower and fruit period in Hainan, China is 1-2 months earlier. [0003] Yellow skin is one of the fruits in...

Problems solved by technology

[0009] The above-mentioned published literature discusses the extraction of active ingredients of wampum leaves from different angles. The patent application number 201510116170.0 is to add crushed wampee leaves to the two-phase system, ultrasonically for a certain period of time, then filter wampee leaves, and place the filtrate in Leave it still in a separatory funnel, separate the liquid to take the upper layer solution, and obtain the total flavonoids of wampee leaves; the patent application number is 201310247660.5 is to extract the wampee fruit powder with ethanol under reflux, and extract the clear liquid with n-butane, and then vacuum Dried into an extract to obtain the extract of japonica root; the journal titled the process research of macroporous adsorption resin purification of total flavonoids of japonica root is to use macroporous resin to purify the total flavonoids of jasmine root; the above three different Extraction methods are used to obtain the effective components of Lycium barbae for different purposes, but some methods are not completely extracted, which makes the resources of yellow bark leaves not fully utilized
