      Validated high-performance thin-layer chromatographic method for determination of diacerein in the presence of degradation products formed under ICH-recommended stress conditions
      J. Rao*, K. Chauhan, K. MAHADIK (*Poona College of Pharmacy, Bharati Vidyapeeth University, Pune, Maharashtra, India)

      Abstract No. F-234 61st IPC (2009). A stability-indicating HPTLC method is reported for estimation of diacerein in the presence of its degradation products. HPTLC on silica gel with toluene - ethyl acetate - formic acid 50:30:1. The hRf value of diacerein was 39. Densitometric analysis at 254 nm. The method was found to be linear in the range of 100-600 ng/band. The method was validated regarding stability. The sample was subjected to different stress conditions (acid/base hydrolysis, oxidation, photolysis, thermal) and showed extensive degradation in alkaline medium and mild degradation under acidic and oxidative conditions. The method allowed separation of diacerein from different degradation products.

      Analytical Chemistry - An Indian Journal 8(1), 29-33 (2009). A sensitive and accurate HPTLC method has been developed for the determination of eugenol from the leaf and berry powder of Pimenta dioica (L) Merr. The leaf and berry powders were extracted with methanol. HPTLC on silica gel with ethyl acetate - methanol - water 6:2:1. Detection and quantification by densitometry at 280 nm. Linear response to eugenol was found to be in the concentration range of 200-600 ng/band. The developed method can be used for routine quantitative monitoring of eugenol from the dried leaf and berry powder of Pimenta dioica (L) Merr.

      S. SARFARE*, S. MENON, S. SHAILAJAN (*Herbal Research Lab, Ramnarain Ruia College, Mumbai 400019, India)

      Asian Journal of Plant Sciences 9(1), 44-50 (2010). Beta-sitosterol is one of the major phytoconstituents in cornsilk (style and stigma of Zea mays Linn.). An HPTLC method for the standardization of cornsilk as a bioavailable source of beta-sitosterol is reported. HPTLC of methanolic extracts of dried cornsilk and plasma of rabbits (1 h after injection of plant slurry) on silica gel with toluene - ethyl acetate - methanol - glacial acetic acid 80:10:5:3 with chamber saturation for 30 min. Detection by treatment with Liebermann-Burchard reagent. Beta-sitosterol was well resolved with an hRf value of 48. Quantitative determination by fluorescence measurement at 366 nm. The method was suitable for the pharmacokinetic study (absorption - elimination). The study confirmed the bioavailability of beta-sitosterol from cornsilk, which is therefore a potential natural source of beta-sitosterol.
