Asian J. Chemistry 22(1), 27-30 (2010). HPTLC of simvastatin (in bulk and tablet dosage form) on silica gel with toluene - ethyl acetate - formic acid 10:3:1. The hRf value of simvastatin was 26. Densitometric evaluation at 242 nm. The method was linear in the range of 200-1000 ng/band.
Asian Journal of Chemistry 22(10), 8117-8120 (2010). HPTLC of beta-sitosterol in leaves, roots and seed oil of 3 species of Jatropha. Chromatographic separation on silica gel with toluene - methanol 9:1. The hRf value of beta-sitosterol was 54. Derivatization with anisaldehyde-sulfuric acid reagent, followed by heating at 120 °C. After derivatzation densitometric evaluation at 525 nm. The method was linear in the range of 100-500 ng/band. The proposed method was used for the estimation of beta-sitosterol in extracts of different species of plants. The presence of beta-sitosterol in samples was confirmed by multi-wave length scanning.
Research Journal of Pharmaceutical, Biological and Chemical Sciences 1(4), 354-359 (2010). TLC on silica gel with toluene - methanol - triethylamine 12:6:1 with chamber saturation for 15 min. Densitometric evaluation at 290 nm. The hRf value was 23 and 67 for famotidine and domperidone, respectively. The method was found to be linear in the range of 100-500 ng/band. The recovery was 98.8 %.
J. AOAC Int. 93, 1180-1191 (2010). TLC of tropisetron and its acid-induced degradation products on silica gel with methanol - glacial acetic acid 22:3 with chamber saturation for 45 min. Detection under UV light at 254 nm. Quantitative determination by scanning at 285 nm. The hRf values were 44, 84, and 92 for tropisetron and degradates I and II, respectively. Linearity was between 1 and 10 µg/zone. Mean accuracy was 100.2 %. The precision was 0.64 %.The limit of detection and quantification for tropisetron was 0.26 and 0.80 µg/zone, respectively. The intraday and interday precisions were evaluated by assaying freshly prepared samples of tropisetron in triplicate concentrations, i. e. 3, 5, and and 9 µg/zone, resulting in 99.8 %, 100.3 %, and 100.4 %, respectively, for interday precision and 99.7 %, 100.2 %, and 99.7 %, respectively, for intraday precision (with a precision of 0.9 %, 0.6 %, 0.8 % and 0.6 %, 0.4 %, 0.6 %, respectively).
International Journal of ChemTech Research 2(2), 1042-1046 (2010) HPTLC on silica gel with dichloromethane - methanol 9:1 in a twin-trough chamber saturated for 30 min. The hRf value was 70. Densitometric evaluation in absorbance mode at 254 nm. The method was linear in the range of 400-2000 ng/band. The average recovery was 101.2 %.
Rec. Nat. Prod. 3/4, 178-186 (2009). An HPTLC method has been reported for quantitative estimation of alpha-mangostin in fruit pericarp of Garcinia mangostana (Hypericaceae). HPTLC on silica gel with chloroform - methanol 9:1 in a saturated chamber (10 min). The plate was derivatized with anisaldehyde sulfuric acid reagent. Densitometric quantification at 382 nm. Alpha-mangostin was detected as a compact band with hRf value of 46. The method was linear in the range of 1-5 µg/band. The maximum yield of alpha-mangostin was obtained from the plant by hot extraction with methanol.
B. Fried, R. Toledo (Eds): Biomphalaria snails and larval trematodes. Springer 20119. Chapter 4. This book chapter reviews TLC, HPTLC and other methods for the analysis of larval trematodes from Biomphalaria snails. The analysis of different classes of organic compounds is described: neutral and polar lipids, glycolipids, lutein, beta-carotene, sugars and amino acids. Various TLC and HPTLC phases and developing solvents were used.
62nd Indian Pharmaceutical Congress Abstract No. F-252 (2010). TLC of alizarin and betulinic acid on silica gel with toluene – ethyl acetate – formic acid 18:3:1. The hRf values were 53 and 58 for betulinic acid and alizarin, respectively. Quantitative determination by absorbance measurement at 287 nm. The method was linear in the range of 60-160 ng/band for alizarin and 300-800 ng/band for betulinic acid. The average recovery was in the range of 99.4-99.6 % for both compounds.
