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.
