Abstract
This study examined the antimicrobial, antioxidant, and tyrosinase inhibitory activities of bioactive compounds extracted from two starfish, Asterina pectinifera and Asterias amurensis, using solvent extraction after hydrolysis. Methanol and acetone fractions collected by stepwise extraction from specimens were subjected to silica gel column chromatography (SGCC) (200 mesh and 400 mesh), followed by high-performance liquid chromatography (HPLC). Two fractions (7:3 and 5:5 chloroform : methanol ratio, v/v) eluted using silica gel column chromatography from the two starfishes showed higher antimicrobial activity against Propionibacterium acnes and dermatophyte fungi (Epidermophyton floccosum, Microsporum audouinii, Trichophyton ferrugineum, Trichophyton mentagrophytes, and Trichophyton rubrum), antioxidant activity (, mg/mL), and tyrosinase inhibitory activity compared to the other fractions. The final fractions obtained from Asterina pectinifera (RT 7.53, 8.93, and 10.48 min) and Asterias amurensis (RT 5.02 min) by SGCC (400 mesh) and HPLC from two SGCC fractions (200 mesh) showed 8.94 and 15.59 mg/mL antioxidant activity () and 46.89 and 40.19 % tyrosinase inhibitory activity, respectively. Extracts from starfishes are potential cosmetic basic material.
