Abstract
. Flavonoids can be found in every organ of plants and has a role as natural antioxidant. The aim of this research was to investigate the influence of maceration and drying time to the level and the type of flavonoids from some leaves of plants located in Taman Wisata Alam Pangandaran. This research used CRD (Completely Randomized Design) with 2 factorial design. The first factor was soaking time of the plant extract in ethanol 96% for 24 hours and 48 hours, the second was drying time for 14 and 21 days. Sample used were Bungur (Largerstoremia speciosa L.), Mahoni (Swietenia macrophylla), Nyamplung (Calophyllum inophyllum L.), dan Vitex (Vitex pubescens Vahl.) leaves. Qualitative parameter was determined from the change of color of the solution used the reagent, as well quantitatively by spectrophotometer of 415nm. Flavonoid type was then analyzed using spectrophotometer at 250-560nm. Quantitative analysist of 2 ways ANOVA showed that all groups were shown significance influence of maceration and drying with optimum flavonoid level varying from one to another. Flavonid type was also ranging from antocyanidin and antocyanin.
