<p><b>OBJECTIVE</b>To study the curative effects of Xianling Qianggu koufuye (XLQG) on postmenopausal osteoporosis in ovariectomized femalerats.</p><p><b>METHOD</b>Sixty femaleSprague-dawley ratsaged 12-months were used, 50 of them were ovariectomized and randomly divided into 5 groups ovariectomized (OVX), OVX + Nylestriol, OVX + XLQG (high dose, middle dose, low dose), and the others were sham-operated group. Rats were treated with drugs starting at the 45 day after the operation for 90 days. Double in vivo fluorochrome labeling was administered to all rats. At the end-point of study, the blood was collected to detecte the contents of ALP and StrACP in serum, and the fourth lumar vertebra (LV4) and femurbone sections were cut and stained for bone histomorphometric analyses, biomechanical analyses and BMP analyses.</p><p><b>RESULT</b>XLQGKFY decreased greatly the StrACP content, increased BMP and bone stiffness, and improved the bone biomechanical property.</p><p><b>CONCLUSION</b>Xianling Qianggu koufuye has a curative effect on postmenopausal osteoporosis, which provides for clinical use.</p>
