Impact of solvent on the characteristics of standardized binahong leaf (Anredera cordifolia (Ten.) Steenis)

Background: Binahong is a plant that has the potential to be used as a traditional herbal medicine in Indonesia, and has several kinds of classes of compounds, one of them is a flavonoids glycosides (vitexin). Previous research reported that binahong leaves have pharmacological activities as antihyperglycemic, antihyperlipidemic, antibacterial, and others. A traditional plant that has proven efficacious needs to be standardized to ensure the quality and its safety. Objective: This study aimed to characteristics of binahong leaves simplicia obtained from Bogor, West Java. Materials and Methods: The crude extract was obtained by the maceration method using 40%, 70%, and 96% ethanol solvent. The selected extract then standardized, which includes macroscopic and microscopic observations and sets the standard parameter values binahong leaf extract. Parameters LCMS to identify active compounds semi-quantitatively. Results: The yield of binahong ethanol extract from 40%, 70%, 96% showed a value of 10.9%, 11.4%, and 12.32%, respectively. From these results, 96% ethanol extract has proceeded for standardization. Macroscopic observation results showed that binahong leaves simplicia has a fine and notched form with 5-10 cm long and 3-7 cm diameter. The microscopic binahong leaves contain palisade tissue, parenchymal tissue, chlorophyll grains, rosette Ca-oxalate crystals, and spiral type. Phytochemical screening of binahong leaves showed the presence of alkaloids, flavonoids, saponins, tannins, steroids, and phenolic compounds.The standardization of binahong leaves ethanol extract down showed a levels of ethanol-soluble extract> 14.8%, water-soluble extract content > 13.5%, drying < 10%, water content < 8.9%, total ash content < 7.2%. LCMS profiles showed that ethanolic extract 40%, 70%, and 96% all contained vitexin at retention time 5.02 minutes, and m/z values 433.1111. Conclusion: 96% ethanolic extract of binahong leaves contains vitexin with pharmacognostic parameters carried out following the standards listed in the Indonesian herb pharmacopeia.
