Problems solved by technology

The traditional medicinal parts are only underground tubers, while the above-ground parts and fibrous roots, which account for more than half of the whole plant, are discarded as waste, which is a great waste of plant resources and pollutes the environment.

Embodiment 1

[0020] Embodiment 1, the preparation of white and extract

[0021] The coarse powder of white root and fibrous root was extracted according to the following three methods, and the content of stilbene components in the extract was determined by spectrophotometry; the antioxidant and antioxidative properties of each extract were evaluated by tyrosinase inhibition method and DPPH free radical scavenging test. Whitening effect.

[0022] (1) Supercritical CO 2 Extraction

[0023] Take white root and fibrous root, pulverize and sieve (20 mesh), weigh 100g, put in extraction kettle (1L), extraction pressure is 30MPa, extraction temperature is 40°C, 95% ethanol is used as entrainer, and the amount added is 0.5 times of the medicinal material amount, The separation tank pressure is 4.0MPa, CO 2 The mass flow rate is controlled at 50-70kg / h, and the extraction time is 1.5h. The extract was concentrated to dryness under reduced pressure below 60°C, and then dried in vacuo.

Abstract

A whitening and anti-oxidation composition containing Bletilla striata (Thunb) Reichb. f. and Saururus chinensis (Lour.) Baill, and a skin care cream using the composition as an active ingredient. The composition comprises the following components in parts by weight: 0.2%-2.0% of fibrous root extract of the Bletilla striata (Thunb) Reichb. f. and 0.2%-2.0% of root extract of the saururus chinensis (Lour.) Baill. The composition uses fibrous roots of the Bletilla striata (Thunb) Reichb. f. and rhizomes of the saururus chinensis (Lour.) Baill as raw materials; the fibrous roots and the rhizomes are non-traditional medicinal parts of the traditional Chinese medicines, the Bletilla striata (Thunb) Reichb. f. and the saururus chinensis (Lour.) Baill, so that the efficient and comprehensive utilization of medicinal resources can be improved. Using supercritical CO 2 fluid extraction and ultrasonic methods to extract stilbene type and lignan type functional components in this composition avoid high temperature treatment, thereby preventing the transformation of the functional components. The skin care cream prepared from the composition has remarkable anti-oxidation and melanogenesis inhibition effects, is mild and non-irritating, and has high skin safety.

Description

technical field [0001] The invention relates to the field of skin care products, in particular to a whitening and anti-oxidation composition containing white and three white grasses and a skin cream containing the composition. Background technique [0002] As a sunrise industry, the beauty and cosmetics industry has grown at an average annual rate of 23.8% since its start in the mid-1980s, which is much higher than the average growth rate of the national economy. According to the latest retail statistics released by the National Bureau of Statistics, in April 2018, the total retail sales of cosmetics was 19.5 billion, a year-on-year increase of 15.1%, which was much higher than the growth level of the overall social consumer goods retail sales. The cosmetics industry has become one of the very important supporting industries in the country's consumption upgrade. [0003] Since ancient times, Chinese aesthetics have regarded white as beauty, and there is a saying that "one w...
