| 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. | 2005 | 15771898 |
