Abstract: One new isoflavone glucoside, caviunin 7-O-[β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside] (10) and a new itaconic derivative, (E)-4-methoxy-2-(3,4-dihydroxybenzylidene)-4-oxobutanoic acid (15) along with series of isoflavones and flavonols with their glucosides (1-9 and 11-14) and a lignan glucoside (16) were isolated from the ethanolic extract of Dalbergia sissoo leaves. The structures of these compounds were established on the basis of IR, UV, (1)H and (13)C NMR, DEPT, COSY, HSQC, HMBC and MS data. All compounds (1-16) were assessed for osteogenic activity in primary calvarial osteoblast cultures. Compounds 1-4 and 10 increased alkaline phosphatase activity and mineralization thus resulting in significant osteogenic activity.
