J. Planar Chromatogr. 32, 243-249 (2019). HPTLC of stigmasterol (1) and cinnamic acid (2) in Pluchea dioscoridis on silica gel with chloroform - methanol - acetic acid 93:5:2. Quantitative determination of (1) by absorbance measurement at 254 nm. Compound (2) was detected by spraying with p-anisaldehyde and quantified under UV light at 513 nm. The hRF values for (1) and (2) were 57 and 19, respectivley. Linearity was between 200 and 1400 ng/zone for (1) and (2). The intermediate precision was below 2 % (n=6). The LOD and LOQ were 39 and 117 ng for (1) and 43 and 129 ng for (2), respectively. Recovery rate was between 98.8 and 99.4 % for (1) and 98.4 and 99.0 % for (2).
