Two novel hydrolysable tannins, potassium brevifolincarboxylate and acaindinin, together with eight known tannins-1-O-galloyl-β-D-glucose, 1,2,3,6-tetra-O-galloyl-β-D-glucose, corilagin, geraniin, acetonylgeraniin A, euphormisin M-2, repandusinic acid A, and chebulagic acid, as well as two flavonoid glycosides-quercetin 3-O-β-D-glucoside and rutin, were isolated from Acalypha indica. Their structures were elucidated on the basis of chemical and spectroscopic evidence.
