by high-performance thin-layer chromatography method. J. Planar Chromatogr. 31, 337-342 (2018). HPTLC of betulinic acid (1), oleanolic acid (2) and lupeol (3) in Achyranthes aspera on silica gel with benzene – ethyl acetate – formic acid 679:227:94 for (1), n-hexane – ethyl acetate – glacial acetic acid 40:20:1 for (2) and n-hexane – ethyl acetate 4:1 for (3). Detection by spraying with anisaldehyde sulfuric acid reagent for (1) and (2) and ceric ammonium sulfate for (3), followed by heating at 105-110°C for 5-10 min. Quantitative determination by absorbance measurement at 530 nm for (1) and (2) and 366 nm for (3). The hRF values for (1) to (3) were 79, 46 and 44, respectively. Linearity was between 2-10 μL/zone. LOD and LOQ were 1 and 4 ng/zone for (1), 1 and 3 ng/zone for (2), and 2 and 5 ng/zone for (3), respectively.
