Abstract

Curculigo latifolia is a plant in the Hypoxidaceae family commonly used in herbal medicine. The study objective was to evaluate the antioxidant and anti-elastase properties of C. latifolia extracts in vitro and silico as a candidate for antiaging active ingredients. This study identified secondary metabolites of the hexane (HE), ethyl acetate (EAE), and ethanol extracts (EE) from the root (R), stem (S), and leaf (L) organs by LC-ESI-MS and evaluated in vitro antioxidant and inhibitor elastase activity. An antioxidant evaluation was performed using ABTS, Beta Carotene Bleaching (BCB), and Ferric Reduction Antioxidant Power (FRAP). Evaluation of anti-elastase was carried out using elastase and followed by an in silico study of molecular docking using the target protein elastase (1B0F). Fifteen C. latifolia metabolites were identified in C. latifolia extracts, most of which were phenolic compounds. In antioxidant testing, REE, REAE, SEE, and SEAE extracts showed potent antioxidant activity based on the ABTS, BCB, and FRAP methods. In anti-elastase testing, it was found that SEE, REE, REAE, and RHE extracts gave powerful inhibition of elastase activity (in the ranges of 16.89 to 27.91 µg/mL). The in-silico study demonstrated the potential of the identified metabolites to bind to the target protein 1B0F involved in remodeling the skin aging process. This research concludes that the extracts from C. latifolia have the potential to serve as an active antiaging source.
