A new phenol derivative isolated from mangrove-derived fungus Eupenicillium sp. HJ002

A new phenol derivative, 3-chloro-5-hydroxy-4-methoxyphenylacetic acid methyl ester (1), along with five known compounds methyl 4-hydroxyphenylacetate (2), cytosporone B (3), (R)-striatisporolide A (4), (R)-butanedioic acid (5) and ergosterol (6) were isolated from the mangrove-derived fungus Eupenicillium sp. HJ002. Their structures were established by spectroscopic methods, GIAO based ¹³C NMR chemical shift calculations and comparison with the data of literature. Compounds 1–5 were isolated from Xylocarpus granatum Koening-derived fungus for the first time.
