Abstract

Five flavonol glycosides (1–5) and two naphthalene dimer glycosides (7 and 8), including three new compounds (1, 2 and 8), were isolated from the leaves of Diospyros montana. The structures of the isolated compounds were determined by spectroscopic analysis. One of the isolated compounds (1) showed DPPH radical scavenging activity.
