Isopropanolic Cimicifuga racemosa is favorable on bone markers but neutral on an osteoblastic cell line

摘要

Postmenopausal women treated with an isopropanolic extract of Cimicifuga racemosa underwent a decrease in the urinary concentration of N-telopeptides, a marker of bone resorption, and an increase in alkaline phospha-tase, a marker of bone formation, at the third month of therapy. Serum from treated women did not modify the activity of alkaline phosphatase or the expression of three genes, runt-related transcription factor-2 (Runx-2), alkaline phosphatase, and osteocalcin, when added to the MC3T3-E1 osteoblastic cell line.
