Two New Secondary Metabolites from Xylaria sp. cfcc 87468

A new isocoumarin glycoside, 3R-(+)-5-O-[6'-O-acetyl]-α-d-glucopyranosyl-5-hydroxymellein (1), and a new phenylethanol glycoside, (−)-phenylethyl-8-O-α-l-rhamno-pyranoside (2), were isolated from the ethyl acetate extract of the fungus Xylaria sp. cfcc 87468, together with five known steroids,...

description A new isocoumarin glycoside, 3R-(+)-5-O-[6'-O-acetyl]-α-d-glucopyranosyl-5-hydroxymellein (1), and a new phenylethanol glycoside, (−)-phenylethyl-8-O-α-l-rhamno-pyranoside (2), were isolated from the ethyl acetate extract of the fungus Xylaria sp. cfcc 87468, together with five known steroids, β-sitosterol (3), stigmast-4-en-3-one (4), ergosterol (5), (22E)-cholesta-4,6,8(14),22-tetraen-3-one (6), and 4α-methyl- ergosta-8(14),24(28)-dien-3β-ol (7). The structures of compounds 1 and 2 were elucidated by MS, extensive 1D and 2D NMR spectroscopy, and the circular dichroism (CD) spectroscopy.
