whole-plant powder by High-Performance Thin-layer Chromatography. J. Planar Chromatogr. 19, 68-72 (2006). HPTLC of oleanolic acid on silica gel with dichloromethane - toluene - acetone - methanol 30:40:15:3. Detection by spraying with Liebermann-Burchard reagent; quantification by densitometry at 529 nm. Detection and quantitation limits were 0.1 µg and 0.5 µg, respectively. Oleanolic acid response was linear over the range 1 to 9 µg. The validated HPTLC method can be used for routine quality-control analysis of Oldenlandia corymbosa L. whole-plant powder and for quantitative determination of oleanolic acid.
