Abstract

The invention discloses a method for extracting anti-ultraviolet radiation active substances from seaweed, which comprises the following steps: (1) pretreatment; (2) ultrasonic extraction; (3) freezing and alcohol precipitation; (4) centrifugal removal of impurities; (5) Decolorization to obtain a white anti-ultraviolet radiation active substance. The method adopts an integrated technology combining low-concentration methanol, ultrasonic technology extraction and solid-phase small column separation and purification technology, and maximizes the extraction of the Active substances, the anti-ultraviolet radiation active substances of the seaweed extracted by this method have obvious ultraviolet light absorbing ability in the UVB (280~320nm) segment and 320~360nm (UVA), which is very suitable for cosmetics and has a great effect on daily sun protection. Obvious effect.

Description

technical field

[0001] The invention belongs to the technical field of seaweed, and in particular relates to a method for extracting anti-ultraviolet radiation active substances from seaweed. Background technique

[0002] Sea radish, also known as red cabbage, cow hair vegetable, gum vegetable, etc. Rhodophyta Cladophyceae Cladophyceae genus, annual red algae. The algal body is purple-red, yellowish-brown to brown, soft leathery, tough after drying, 4-10cm high, up to 15cm, clustered, short main branch, cylindrical or sub-cylindrical, about 4mm wide, irregular dichotomous branches , often constricted at the branch. Seaweed likes to grow on rocky reefs outside the sea that are impacted by waves and have high salinity. The vertical distribution can reach about 2 meters, and it likes sunshine. my country's coastal areas are distributed in Liaoning, Hebei, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Taiwan and other coastal areas, and the southeast coast is widely distrib...
