Abstract:

Context: The medicinal plants have enormous pharmacological properties with fewer side effects. Today, there is an increasing demand of medicinal plants as an anti-aging and antiwrinkle agent.

Objective: The aim of this study is to evaluate the antioxidant, anti-aging and anti-wrinkle potential of Salvia officinalis.

Materials and Methods: Salvia officinalis (Lamiaceae) is folk medicine of Asia and Latin America. Powdered crude drug 100 g was successively extracted in a soxhlet apparatus with petroleum ether (60-80ºC), chloroform and methanol. After successive solvents, extraction methanolic extract was used for testing of antioxidant potential using DPPH assay. Further, the antiaging potential of the extract was investigated by the inhibitory effect of various enzymatic estimations i.e. Col-I, Ela- I and Hya-I inhibitory assays on early aging human skin fibroblasts. The antiwrinkle potential of plant Salvia officinalis was done by using a UV light-induced photoaging model.

Results: Phytochemical analysis showed the presence of glycosides, alkaloids flavonoids, and triterpenoids, saponins and Phenolic compounds at a high level. The extract showed inhibitory concentration (IC50:24.65) and ascorbic acid. The standard antioxidant showed inhibitory concentration (IC50:20.10). In enzymatic estimations assay, the Col-I, Ela-I and Hya-I of extract were assessed showing inhibitory concentration as Col-I (IC50:21.36), Ela-I (IC50:35.05) and Hya-I (IC50:23.44), respectively. Thus, MeOH extract of Salvia officinalis can inhibit 50% of the activity of agingrelated enzymes Col-I, Ela-I and Hya-I. The wrinkle score of negative control i.e. UV treated group was 2.83±0.408, and MeOH extract of Salvia officinalis treated group is 1.83 ±0.753.

Conclusion: This study concluded that MeOH extract of Salvia officinalis has confirmed the high antioxidant potential and in vitro and in vivo inhibitory potential of antiaging enzymes assessed, thus they could be used for further development of cosmetic products and nutraceuticals.

Keywords: Salvia officinalis, sage, photoaging, fibroblast, wrinkle score, nutraceuticals.
