DETERMINATION OF FLAVONOID CAPACITY BY USING ETHANOL EXTRACT OF CIPLUKAN LEAVES (Physalis angulata L.) USING UV-VIS SPECTROFOTOMETRY METHODS

Ciplukan leaves (Physalis angulata L.) have a composition of main phytochemical compounds including alkoloids, phenolics, tannins, flavonoids that can function as antioxidants, antibacterial, antiviral, anti-inflammatory, antiallergic, and anticancer. The purpose of this study was to identify and determine the levels of flavonoid compounds contained in the Ethanol Extract of Ciplukan Leaf (Physalis angulata L.) Ethanol extraction of Ciplukan Leaves (Physalis angulata L.) was carried out using the maceration method using 96% ethanol solvent, a flavonoid identification test was carried out on the Ethanol Extract of Ciplukan Leaves with the addition of Mg metal powder, concentrated HCI, and 10% NaOH, then determining Flavonoid levels using the UV-Vis spectrophotometric method using Quercetin as a comparative raw material. A qualitative test of Ethanol Extraction of Ciplukan Leaves (Physalis angulata L.) containing flavonoids has been carried out. Determination of flavonoid levels using UV-vis spectrophotometry obtained 0.0235%.
