Description A simple and fast method was developed for simultaneous quantitative determination of three biologically active phenolic compounds i.e. quercetin, rutin and coumaric acid in flowers of Rhododendron orboreum using high-performance thin-layer chromatography (HPTLC). The separation was performed on TLC aluminium plates precoated with silica gel RP-18 F-254S. Good separation was achieved in the mobile phase of methanol-water-formic acid (40:57:3, v/v/v) and densitometric determination of these compounds was carried out at 280 nm in reflectance/absorbance mode. The linear regression data for the calibration plots showed a good linear relationship with r = 0.9971, 0.9953 and 0.9960 quercetin, rutin and coumaric acid, respectively. Accuracy of the method was checked by recovery study conducted at two different levels with the average recovery of 99.90%, 99.02% and 99.16% for quercetin, rutin and cournaric acid, respectively. The present method is being reported first time and may be used for routine quality control of the flowers of R. arboreum.
