Osteoporosis is one of the major health problem affecting postmenopausal women. Estrogen deficiency results in an increase in bone turnover, lead to bone resorption and an increase risk of fracture. The aim of this study was to evaluate the effects of Capsosiphon fulvecense extract (CSF) on the collagen content of the connective tissues and alkaline phosphatase activity of serum in ovariectomized estrogen-deficient rats. Three groups were surgically ovariectomized (OVX). The fourth group was sham operated. Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rats (Sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with CsF at 50mg/kg body wt (OVX-CSF50) and ovariectomized rats supplemented with CsF at 200mg/kg body wt (OVX-CSF200). The Capsosiphon fulvecense extracts were orally administrated at 1mL per day. The ovariectomy caused a decreasing in the levels of collagen content in bone, cartilage, skin and lung tissues. However CSF groups, supplementation with Capsosiphon fulvecense extract, were increased the level of collagen content in bone, cartilage, skin and lung tissues than OVX-control group. Alkaline phosphatase activity also were increased and calcium levels were decreased than OVX-control on serum. These results suggest that Capsosiphon fulvecense supplementation prevents postmenopausal bone loss, thus it may be used possibly to improve the quality of life in menopausal women.
