title: Three drimane sesquiterpene glucoside from the aerial parts of Dryopteris fragrans (L.) schot.
abstract: Sesquiterpene glucoside was isolated from the aqueous extract of the aerial parts of Dryopteris fragrans (L.) schot. Three new sesquiterpene glucoside xianglinmaojuesides A-C (1-3), 3beta,11-dihydroxy-drim-8 (12)-en-11-O-beta-D-glucopyranoside (1), 3beta,11-dihydroxy-drim-8(12)-en-3-O-beta-D-glucopyranoside (2), and 11,14-dihydroxy-drim-8(12)-en-11-O-beta-D-glucopyranoside (3) were finally obtained by reversed-phase HPLC and their structures were elucidated by HRESIMS and 1D, 2D NMR analyses.
