Abstract

Ceiba pentandra (L.) stem bark plant contains tannin, flavonoid, alkaloid, terpenoid, and saponin compounds. It is known that flavonoid compounds have a potential for inhibition activity of an α-glucosidase enzyme. The purpose of this research is to know the α-glucosidase inhibition activity of the fraction of n-hexane, ethyl acetate, and water. These three fractions measured α-glucosidase inhibition activity by spectrophotometric UV-vis method. The fraction extract with IC50 values can best be done an analysis of active compounds using LCMS/MS methods, and results of the suspected compound do the binding molecule with a receptor model isomaltase α-glucosidase uses AutoDock Vina so that bond can predict drug active compounds. The results of this research activity are inhibition of α-glucosidase stem bark in the fraction of n-hexane 4,60 μg/mL, ethyl acetate fraction 8,55 μg/mL and fractions of the water 5,61 μg/mL. Analysis of the compound fraction of water by LCMS/MS eluted at the retention time 3,61 seconds allegedly derivative compounds (+) catechin and on retention time 8,70 minutes allegedly derivative compounds vavain. Vavain derivative compounds, (+) catechin, acarbose and quercetin each has its own docking score of -8,1; -8,8; -6,2 and -7,6 kcal/mol and has a semblance of bonding on amino acid Glu276 which is a residue catalytic role in hydrolysis reactions. Equality on the sides of active chemical bonds is expected to have the same activity as drug inhibition of the enzyme α-glucosidase.

Abstract

Brown macroalgae (BM) which contain fucoxanthin exhibited high antioxidant activity. This study was performed to examine antioxidant, anti-collagenase, anti-elastase, anti-tyrosinase activities, and effect on cell viability of Human Dermal Fibroblast adult (HDFa) of BM, Turbinaria decurrens Bory. T. decurrens dried powder were macerated by ethanol to obtain extract (ETD) and was fractination by column chromatography to obtain fraction (FTD). Fucoxanthin content was determined using HPLC. The antioxidant activities, anti-collagenase, anti-elastase, and tyrosinase inhibitory assay were performed. The effect of ETD and fucoxanthin standard on cell viability were conducted on HDFa cell-induced by hydrogen peroxide (H2O2). The HPLC analysis showed that ETD and FTD contain fucoxanthin of 284.9±3.3µg/g and of 653.4±30.6µg/g dry-weight, respectively. The antioxidant assay showed that ETD and FTD produced high antioxidant activity by ferric reducing antioxidant power (FRAP) and b-carotene bleaching (BCB) methods that were comparable to fucoxanthin. ETD exhibited significantly higher tyrosinase inhibitory than kojic acid (p<0.01), while FTD had a comparable effect to kojic acid. The result also revealed that ETD and FTD produced anti-elastase and anti-collagenase (matrix metalloproteinase-1 (MMP-1). Fucoxanthin and ETD were able to maintain cell viability on HDFa cell-induced H2O2. This study suggests that T. decurrens may be effective to prevent skin aging and wrinkle formation, possibly through the antioxidant activity and maintain cell viability of fibroblast.
