Utilizing Different Drying Effect for Rubusfraxinifolius Leaves Phytochemical Constituent's Correlation

Abstract

Rubusfraxinifolius is a class that has a place with the Rosacea family, which develops in the rugged timberlands in Indonesia. The investigation meant to decide the effects of air-drying (AD) and oven drying (OD) of the youthful R. fraxinifolius leaves and contrast them with the fresh leaves (FL) to watch the phytochemical substance and bioactivities. Phytochemical substance of the examples were resolved dependent on subjective measure, totalphenolic, also, total flavonoid, while bioactivities were assessed on antioxidant agent DPPH free radical rummaging effect, ?-glucosidase inhibitory activity, and antibacterial measures. LCMS-MS (Liquid Chromatography-Mass SpectrometryMass Spectrometry) was utilized for the quantitative examination of normally happening phytochemicals. The methanol extract of FL had the most elevated free radical rummaging action against DPPH with IC50 of 45.51 5.03g/mL, absolute phenolic substance, and total flavonoid content contrasted with those of AD and OD. Be that as it may, AD had the most noteworthy ?-glucosidase inhibitory action among others. The antibacterial action of the youthful leaves indicated that there was no action distinction in both new and dried conditions. In light of LCMS-MS investigation, it was uncovered that Luteolin-7-O-glucoronide, a functioning antioxidant flavonoid.
