ABSTRACT QUALIFICATION OF COMPOUNDS WITH BIOLOGICAL PROPERTIES AND EVALUATION ON ANTI-ACETYLCHOLINESTERASE ACTIVITY OF DIFFERENT EXTRACTS FROM BROWN ALGAE SARGASSUM HENSLOWIANUM Nguyen Thi Ngoc Hoai, Nguyen Thi Phuong, Nguyen Van Hieu Ho Chi Minh City University of Food Industry Algae is a potential source of substances capable of inhibiting the enzyme AChE. The study exhibited the presence of some compounds with biological properties and anti AChE enzyme activity of brown algae (Sargassum henslowianum) by different environmental extracts. The samples were extracted with methanol, n-hexane, and ethyl acetate at 60°C for 60 minutes. Qualification of compounds with biological properties and anti AChE activity of other extracts according to Yadav and Ellman, respectively. The results showed that methanol extraction contained polyphenol, flavonoids, and carotenoids. AChE of methanol extraction was IC50 550,3 ± 0,45 µg/mL. Ethylacetate and n-hexane extraction contained polyphenol and terpenoid with anti AChE activity was lower in comparison to methanol extract, and their IC50 values corresponded to 606,12 ± 1,31 µg/mL and 609,55 ± 0,35 µg/mL, respectively. Brown algae (Sargassum henslowianum) is a source of anti AChE. Keywords: Acetylcholinesterase, enzyme, methanol, biological properties, Sargassum henslowianum. |
