Abstract
Two new monomeric hydrolysable tannins, acalyphidins M1 and M2, together with fourteen known polyphenols were isolated from the leaves of Acalypha hispida, and characterized as 1-O-galloyl-3,6-(R)- hexahydroxydiphenoyl-4-O-brevifolincarboxyl-β-D-glucose, and an oxidative metabolite of geraniin, respectively, by spectroscopic and chemical methods. A new hydrolysable tannin dimer, acalyphidin D1, which is composed of two moles of geraniin, was also isolated and characterized as an acetonyl derivative.
