A New Flavonol Glucoside from the Leaves of Crypsinus trilobus

Abstract

A new flavonol glucoside, kaempferol 3-O-[2″,4″-di-O-acetyl-6″-O-(E-p-coumaroyl)]-β-D-glucopyranoside (namely crypsinoside A) (1), along with 7 known compounds 2 – 8 were isolated from the leaves of Crypsinus trilobus (Houtt.) Copel. (Polypodiaceae) for the first time. Their structures were elucidated on the basis of HR-ESI-MS, 1D and 2D NMR spectra.
