Abstract
Two polyketides,Griseophenone B(Ⅰ) and Griseophenone C(Ⅱ),were isolated from the ethyl acetate part,which was extracted from the fermentation broth of marine-derived fungus Penicillium sacculum,by silica gel,Sephadex LH-20 column chromatography and recrystallization.The structures of the two compounds were determined by 1D NMR and 2D NMR(HSQC,HMBC).The 13CNMR data of compound Ⅰ and NMR data of compound Ⅱ were reported firstly,and the chemical shifts were assigned using 2D NMR techniques.Compound Ⅱ was isolated firstly from Penicillium sacculum.
