Abstract

This study aimed to search for separate and identify of Quercus acutissima CARRUTHERS tannins. Tannins were extracted with methanol and ethylacetate from acorn powder and identified TLC, UV spectrum, HPLC, IR, GC/MS, and $^{1}H$ NMR. Three spots($R_{f}$ 0.94, 0.84 and 0.29) detected on TLC. These spots gave dark blue color fairly on spraying with 0.3% potassium ferricyanid${\cdot}$0.3% ferricchloride reagent, and these tannins identified as gallic acid, caffeic acid and ellagic acid by UV spectrum, HPLC, IR, GC/ MS, and $^{1}H$ NMR.
