Abstract

The invention belongs to the technical field of marine organism natural products and particularly relates to a method for preparing sargassum horneri powder and extracting fucoxanthin from sargassum horneri. The method includes steps: preparing sargassum horneri powder by cleaning, drying in the shade, drying, powdering, sterilizing and the like; adding extract liquid and steel balls into the sargassum horneri powder, performing oscillatory extraction for 3-10 minutes under weak-light, low-temperature and oxygen-free conditions, centrifuging to obtain supernatant, and subjecting the supernatant to high performance liquid chromatography and vacuum freeze drying to obtain a pure fucoxanthin product. The method has advantages of high efficiency, simplicity, low cost and the like, provides basis for biological resource comprehensive utilization of sargassum horneri and has a potential significant economic value.

Description

technical field

[0001] The invention belongs to the technical field of marine biological natural products, and in particular relates to the preparation of copper algae powder and a method for extracting fucoxanthin in the powder. Background technique

[0002] Copper algae (Sargassum horneri) is a large floating brown algae that is widely distributed in the northern seas of my country. It has the characteristics of wide adaptability, strong stress resistance, and easy cultivation. Economic brown algae.

[0003] Fucoxanthin (also known as fucoxanthin) is a carotenoid substance composed of three elements: carbon, hydrogen, and oxygen, and is widely distributed in some diatoms and large brown algae. Due to the many conjugated double bonds in its chemical structure, it has antioxidant properties and can effectively remove free radicals in organisms. Fucoxanthin can promote the energy consumption of adipocytes by inducing the expression of uncoupling protein 1 in the mitochondria...
