Abstract
A new β-tetralonyl glucoside, methylberchemiaside (1), along with five known compounds (2–6) were isolated from a fungus Colletotrichum sp. GDMU-1 derived from the leaves of Santalum album. Their structures were determined by detailed analysis of spectroscopic data. All compounds were tested for the inhibitory effects on the nitric oxide (NO) production in lipopolysaccharide (LPS)-treated RAW264.7 cells. Among them, compounds 4 and 5 showed moderate anti-inflammatory activity with IC50 value of 30.4 and 8.9 μM, respectively.
