Identification of bioactive compounds from Nannochloropsis sp.

Abstract

Abstract Microalgae are known to have functional components for human life. Exploration of cholesterol-lowering active compounds from microalgae Nannochloropsis in Indonesia is still lacking. This research was aimed to identify bioactive compounds from Nannochloropsis sp that can reduce cholesterol level. Components of Nannochloropsis sp. including proximate, phytochemicals, beta-carotene, beta-sitosterol, stigmasterol, omega 3, and omega 6 were determined. Phytochemical test results showed that microalgae Nannochloropsis sp. positively contained flavonoids, tannin, glycosides, alkaloids, and saponin. Result of beta carotene was 2.74%, beta-sitosterol 7.25% stigmasterol 10.37%, beta carotene 145.26 ppm, omega 6 was 9.86% and omega 3 was 4.38% from total fatty acid.
