Chemical investigation of the dichloromethane extract of Chlorococcum infusionum afforded a mixture of chondrillasterol (1) and 22-dihydrochondrillasterol (2) in a 3:1 ratio as the major sterols, and lutein (3), triacylglycerols (4), fatty acids (5) and hydrocarbons (6) as the minor compounds. The structures of compounds 1 and 2 were elucidated by extensive 1D and 2D NMR spectroscopy, while compounds 3-6 were identified by comparison of their NMR data. © 2020 Chemical Publishing Co..
