International Journal of Pharmacy & Pharmaceutical Sciences 3(2), 227-230 (2011). TLC of beta-sitosterol-D-glucoside and withaferin-A in Withania somifera formulations on silica gel with chloroform - methanol 4:1. The hRf value of beta-sitosterol-D-glucoside was 21 and of withaferin-A 59. Quantitative absorbance measurement at 207 nm. The method was linear in the range of 50-500ng/band for beta-sitosterol-D-glucoside and in the range of 5-50 ng/band for withaferin-A.
simultaneous quantification of eight bioactive secondary metabolites from Cicer
microphyllum by high-performance thin-layer chromatography
J. Sep. Sci. 38, 4021-4028 (2015). HPTLC of eight natural products viz. stigmasterol (1), oleanolic acid-3-acetate (2), oleanolic acid (3), biochanin A (4), genistein (5), pratensein (6), chrysoeriol (7), and luteolin (8) in Cicer microphyllum on silica gel with n-hexane - ethyl acetate - formic acid 90:65:8. Detection by dipping into a solution of cerric ammonium sulfate reagent, followed by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 366 nm. The hRF values for compounds (1) to (8) were 98, 89, 78, 70, 63, 42, 33 and 4, respectively. Linearity was in the range of 100-800 ng/zone for (1) to (8). LOD and LOQ were 60 and 90 ng/zone for (1), (5) and (8), 50 and 90 ng/zone for (2), 90 and 110 ng/zone for (3), 70 and 100 ng/zone for (4) and (6) and 80 and 110 ng/zone for (7). The intermediate precision was below 1.5 % (n=3). Recovery was in the range of 98-100 %.
