Objective: To investigate the secondary metabolites from Penicillium raistrickii.
Methods: Compounds were isolated and purified by normal and reverse phase silica gel, Sephadex LH-20 gel column chromatography and RP-HPLC. Their structures were established by means of spectral techniques and physicochemical properties.
Results: Twelve compounds were identified as pestafolide A(II), 3-methoxy-4-methyl-2,4-dien-pentanoic acid (2),p-hydroxy phenylacetamide (3),2-(2-hydroxy propanamido) benzamide (4), nicotinic acid (5), thymine (6), uracil (7) cyclo (Gly-Ala) (8), (22E,24R)-3β,5α,9α-trihydroxy ergosta-7,22-diene-6-one (9), cerevisterol (10), ergosterol (11) and ergosterol peroxide (12).
Conclusion: All compounds are isolated from Penicillium raistrickii for the first time.
