Objective: In this study, we have evaluated the skeletal effects of butanolic fraction (BF) from Passiflora foetida in an estrogen deficient mice bone loss model.
Study design: Skeletal effect of BF was studied in ovariectomized (OVx) female Balb/c mice. BF (50 and 100mg/kg/day dose orally) was given for 8 weeks. Micro-architecture of long bones, biomechanical strength, formations of mineralized nodule by bone marrow osteoprogenitor cells, osteoid formation and bone turnover markers were studied. One way ANOVA was used to test the significance of effects of Passiflora foetida.
Results: OVx mice treated with BF represented with better micro-architectural parameters at various anatomical positions, better bone biomechanical strength and more osteoprogenitor cells in the bone marrow compared with OVx group. BF did not exhibit uterine estrogenicity.
Conclusion: Oral administration of BF at both the doses (50 and 100mg/kg/day) derived from Passiflora Foetida, was found to afford anti-osteoporotic effect under estrogen deficiency by likely stimulation of osteoblast function and inhibition of osteoclast function.
