Lactobacillus pentosus isolated from Muntingia calabura shows inhibition activity toward alpha-glucosidase and alpha-amylase in intra and extracellular level

Abstract

Lactobacillus pentosus is one of the most prevalence lactic acid bacterium which available in plant-based fermentation. Here, we reported that the cell extract and cell-free supernatant of L. pentosus strain TL 2.7, TL 5.8 and TL 7.8 isolated from Kersen (Muntingiacalabura L.) showed potential anti-diabetic properties by inhibition of alpha-glucosidase and alpha-amylase activity in vitro. All isolated also enhanced the antioxidant capacity through DPPH in vitro test. This initial study will be beneficial for screening and application of functional food with anti-diabetic properties.
