Bio-Activity Evaluation of Hibiscus sabdariffa Linn. in Skin Care and Isolation of Contributory Component

In this study, the calyx part of Hibiscus sabdariffa Linn.(Okinawa) were taken as the study objects. Through the establishment of bioactivity evaluation system and bio-guided isolation method, the components with reversing-senescence activity were identified,it was the first time to evaluate the reversing-senescence potential and clarified the major active component in Hibiscus sabdariffa. and the mechanism of these ingredients is being further studied now. This study suggested that Hibiscus sabdariffa have high possibility to be used as reversing-senescence reagent or skin care products in the future, provided a new considerable way for the regeneration and utilization of plants in nature.
