چکیده
Objective: This study aimed to isolate, identify, and quantify major flavonoid in P. bleo leaves from West Java Regency, Indonesia.
 Methods: Isolation began with maceration, followed by liquid-liquid extraction various chromatographic separations. Identification of isolates was carried out using 2D TLC shifting reagents. Quantification determined the colorimetric method.
 Results: The results showed that extract, ethyl acetate, distilled water fractions contain flavonoids. screening positive for flavonols. vacuum liquid chromatography separated 21 sub-fractions; 12th 13th sub-fractions were predicted flavonols.
 Conclusion: novelty this isolation identification originating Indonesia, i.e. catechin. content compound 3.795±0.096 g QE/ml a purity 94.89%.
