Abstract

The invention discloses a method for extracting anti-irradiation active substances from gloiopeltis furcate. To obtain white anti-irradiation active substances, the method includes the following steps: (1) pre-treatment; (2) ultrasonic extraction; (3) freezing alcohol precipitation; (4) centrifugal decontamination; (5) decoloration. The method includes adopting integrated technologies of a low density methyl alcohol ultrasonic extraction technology and a solid phase small column separation purification technology to extract the active substances to the maximum by controlling the extraction time, the temperature, the methyl alcohol density and the material liquid proportion. The anti-irradiation active substances extracted from gloiopeltis furcate have obvious ultraviolet absorption capability under the UVB (280-320 nm) section and the section of 320-360 nm (UVA), can be applied to cosmetics, and achieve an obvious sunscreen effect in daily life.

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] Seaweed, 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 coasts are distributed in Liaoning, Hebei, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Taiwan and other coastal areas, and the southeast coast is widely distributed, espe...
