dcterms:description
A novel O-deoxyglycoside of a dimeric tetrahydroxanthone, named hirtusneanoside, was isolated from the lichen Usnea hirta. Its structure, including the absolute configurations of the hydroxyl and methyl groups, and biphenyl moiety, was determined by means of extensive spectroscopic data (UV, IR, MS, CD, 1D and 2D NMR) and chemical degradation. Hirtusneanoside has a unique structure containing a tetrahydroxanthone dimer of O-glycoside with a L-rhamnopyranosyl unit, and showed growth inhibitory activities against Gram-positive bacteria A novel O-deoxyglycoside of a dimeric tetrahydroxanthone, named hirtusneanoside, was isolated from the lichen Usnea hirta.
