Echinacoside (ECH), isolated from Cistanche tubulosa (Schrenk) R. Wight stems, has been reported to enhance bone regeneration in MC3T3-E1 cells in vitro. The objectives of this study were to investigate the antiosteoporotic effect of ECH on bone metabolism in the ovariectomized (OVX) rat model of osteoporosis in vivo. ⋯ These results suggest that ECH, as a new class of phytoestrogen, has a remarkable antiosteoporotic activity, and may be a promising candidate for treatment of postmenopausal osteoporosis induced by estrogen deficiency in a natural way through herbal resources.
