Chemical investigation of the dichloromethane extract of Chlorococcum infusionum afforded a mixtureof 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 structuresof compounds 1 and 2 were elucidated by extensive 1D and 2D NMR spectroscopy, while compounds3-6 were identified by comparison of their NMR data.
