Detection by spraying with p-anisaldehyde reagent, followed by heating. Quantitative determination by absorbance measurement at 540 nm. The hRF value of lupeol was 32. Linearity was between 100 and 800 ng/zone. The intermediate intra-day and inter-day precisions were below 2 % (n=6). The LOD and LOQ were 31 and 94 ng/zone, respectively. Recoveries were in the range of 99.2-99.7 %.

Detection by spraying with 3% sulfuric acid in ethanol and heating at 110°C for 10 min. Quantitation by densitometry in absorbance-reflectance mode.

Analytical Chemistry - An Indian Journal 9(2) (2010) (without page number). An HPTLC method has been reported for estimation of beta-sitosterol in whole plant powder of Tridax procumbens. HPTLC on silica gel with toluene - ethyl acetate - glacial acetic acid 40:10:1. Methanolic extracts of the plant material were used. For detection the plate was sprayed with anisaldehyde - sulfuric acid reagent. Densitometric quantification at 550 nm. The method was linear in the range of 10.0-70.0 µg/band. The plant material was found to contain 0.04 % of beta-sitosterol. The proposed method was suitable for routine quality control of plant as well as quantification of beta-sitosterol .
