Glycerols and fatty acids isolated from Micractinium sp. KSF0031

Abstract

From the collected extract from King Sejong Antarctic Station, strain Micractinium sp. KSF0031, led to the isolation of one new monoacyldigalactosyl glycerol (1) and seven known compounds (2-8). Their chemical structures were established using extensive spectroscopic techniques, including 1D, 2D-NMR, and MS, and compared with the published data. To the best of our knowledge, this is the first report to investigate the secondary metabolites from genus Micractinium. The monoacyldigalactosyl glycerol in Micractinium could serve as its chemotaxonomic markers.
