Lanceocrepidiasides A-F, glucosides of guaiane-type sesquiterpene from Crepidiastrum lanceolatum.
From the aerial parts of Crepidiastrum lanceolatum, six guaiane-type sesquiterpene glucosides, lanceocripidiasides A-F were isolated together with five known sesquiterpene glucosides, ixerin Y, crepidialanceosides A and B, and youngiasides A and D, two known megastigmane glucosides, icariside B1 and corchoionoside A, and benzyl 6'-O-beta-D-apiofuranosyl-beta-D-glucopyranoside. Structures were elucidated by spectroscopic analyses.
