Naringin is considered the main effective compound of Drynaria Rhizome, which is used commonly in the treatment of osteoporosis in traditional Chinese medicine. However, we found neoeriocitrin, a new compound isolated from Drynaria Rhizome, showed a better activity than naringin on proliferation and osteogenic differentiation in MC3T3-E1. Both neoeriocitrin and naringin exhibited the best effect on proliferation and osteogenic differentiation at concentration of 2μg/ml. Neoeriocitrin more significantly improved proliferation and alkaline phosphatase (ALP) activity as well as up-regulated Runx2, COLI and OCN expression by 56%, 37% and 14% respectively than naringin. Furthermore, neoeriocitrin could rescue the inhibition effect of cell differentiation induced by PD98059 to some degree. Therefore, neoeriocitrin may be a new promising candidate drug for treatment of osteoporosis.
