A flavonol glycoside-lignan ester and accompanying acylated glucosides from Monochaetum multiflorum

Four acylated glycosides along with six known glycosides were isolated from the leaves of Monochaetum multiflorum. The new compounds were characterized as 4-O-(6'-O-galloyl-beta -glucopyranosyl)-cis-p-coumaric acid, 6'-O-galloylprunasin, benzyl 6'-O-galloyl-beta -glucopyranoside, and a novel diester of tetrahydroxy-mu -truxinic acid with 2 mol of hyperin (monochaetin), based on NMR and MS spectral data and chemical evidence.
