In a sequel to investigate osteogenic potential of ethanolic extract of Cissus quadrangularis (CQ), the present study reports the osteoblast differentiation and mineralization potential of ethyl acetate (CQ‐EA) and butanol (CQ‐B) extracts of CQ on mouse pre‐osteoblast cell line MC3T3‐E1 (sub‐clone 4) with an objective to isolate an antiosteoporotic compound. Growth curve, proliferation, and viability assays showed that both the extracts were nontoxic to the cells even at high concentration (100 µg/ml). The cell proliferation was enhanced at low concentrations (0.1 µg/ml and 1 µg/ml) of both the extracts. They also upregulated the osteoblast differentiation and mineralization processes in MC3T3‐E1 cells as reflected by expression profile of osteoblast marker genes such as RUNX2, Osterix, Collagen (COL1A1), Alkaline Phosphatase (ALP), Integrin‐related Bone Sialoprotein (IBSP), Osteopontin (OPN), and Osteocalcin (OCN). CQ‐EA treatment resulted in early differentiation and mineralization as compared with the CQ‐B treatment. These findings suggest that low concentrations of CQ‐EA and CQ‐B have proliferative and osteogenic properties. CQ‐EA, however, is more potent osteogenic than CQ‐B.
