New megastigmane glucosides from Excoecaria cochinchinensis Lour. var. cochinchinensis

Two new megastigmane glucosides, called excoecariosides A and B were isolated from the leaves of a medicinal Vietnamese plant, Excoecaria cochinchinensis Lour. var. cochinchinensis (Euphorbiaceae) together with seven known compounds. Their structures were elucidated by spectroscopic analyses and chemical reactions including the modified Mosher's method. © 2005 Pharmaceutical Society of Japan.
