SynopsisAs part of an ongoing search for the novel pharmacological activities of Phyllanthus emblica, the present study has shown its type I collagen promoting and anti-collagenase effects on primary mouse fibroblast cells. At a concentration of 0.1 mg ml -1 , emblica extract significantly increased the type I pro-collagen level up to 1.65-fold, and 6.78-fold greater than that of an untreated control, determined by immunocytochemistry and Western blot analysis, respectively. Emblica extract caused an approximately 7.75-fold greater type I procollagen induction compared to the known herbal collagen enhancer asiaticoside at the same treatment concentration (0.1 mg ml )1 ). Moreover, emblica extract inhibited collagenase activity in a dose-dependent manner. Maximal inhibition was observed (78.67 ± 3.51%) at a concentration of 1 mg ml )1 . In summary, emblica extract has a promising pharmacological effect that benefits collagen synthesis and protects against its degradation and could be used as a natural anti-aging ingredient.
