Oxidative stress (OS) is the common mechanism for age-related diseases. The co-occurrence of osteoporosis (OP) and cardiovascular disease (CVD) in postmenopausal women makes it warranted to find a holistic approach for treatment of multiple diseases or conditions. The rhizome of Ligusticum chuanxiong Hort. (CX), which has high anti-oxidant properties and is widely used for CVD treatment in China, might be the potential candidate. In the present study, CX ethanol extract (CXE) was applied to H2O2 induced MG63 cells to study its effects and mechanisms on osteoblastogenesis against OS. CXE was then administered to six-month-old Sprague Dawley sham or ovariectomized (OVX) rats fed either a low saturated fat-sucrose (LFS) or a high fat-sucrose (HFS) diet for 12 weeks, to confirm its anti-osteoporotic effects. The results demonstrated that CXE directly improved proliferation and differentiation in vitro in an H2O2-induced osteoblast cell model by attenuating cellular reactive oxygen species levels and inhibiting osteoblast apoptosis via PI3K/Akt signaling pathway. CXE significantly improved bone properties as revealed by the increase in trabecular bone mineral density and decrease in trabecular separation at proximal metaphysis of the tibia (PT) in HFS-fed OVX rats but not in LFS-fed OVX rats. CXE ameliorated dyslipidemia, greatly reduced lipid deposition and malondialdehyde levels, improved activities of superoxide dismutase, catalase and glutathione peroxidase in the livers of HFS-fed OVX rats. In conclusion, CXE could favor osteoblastogenesis against OS. The ability of CXE to reduce bone loss in HFS-fed OVX rats was associated with its abilities to correct dyslipidemia, and reduce lipid deposition and OS levels.
