ABSTRACT

ABSTRACT

Three new acylated methyl glycosides and two new acylated glycosidic acid methyl esters were isolated after treatment of the crude ether-insoluble resin glycoside (convolvulin) fraction from seeds of Quamoclit pennata BOJER (Convolvulaceae) with indium(III) chloride in methanol. Their structures were elucidated on the basis of spectroscopic data and chemical conversions.
