title: Lasianthionosides A-C, megastigmane glucosides from leaves of Lasianthus fordii.
abstract: From the leaves of Lasianthus fordii, three megastigmane glucosides, lasianthionosides A, B and C, were isolated together with the known iridoid glucoside, asperuloside, deacetylasperuloside and methyl deacetyl-asperulosidate, and a megastigmane glucoside, citroside A. The structures have been elucidated based on spectroscopic analyses and/or X-ray crystallographic analysis.
