J. Planar Chromatogr. 23, 108-111 (2010). HPTLC of gallic acid, ferulic acid, syringic acid, catechin, protocatechuic acid and vanillin on silica gel with toluene - ethyl acetate - formic acid 8:2:1 in a twin-trough chamber previously saturated for 15 min. Quantitative determination by absorbance measurement at 280 nm. Accuracy was between 96.3 and 90.7 %, repeatability between 0.65 and 0.93 %, inter-day precision between 0.80 and 0.90 %, intra-day precision between 0.72 and 0.95 %, and precision between 0.87 and 0.92 %. LOD and LOQ were about 100 and 400 ng/band, respectively. Starting at LOQ, the correlation coefficients were between 0.988 and 0.997.
Abstract No. C-495, 61st IPC (2009). Screening of different phytoconstituents in a polyherbal tablet formulation. TLC of n-hexane, chloroform and methanol extracts of the tablets on silica gel with n-hexane - ethyl acetate 7:3; chloroform-methanol 9:1, and chloroform - glacial acetic acid - methanol - water 8:40:15:10. Evaluation under UV 254 nm as well as under UV 366 nm after spraying with different reagents: 20 % sulfuric acid, aniline-hydrogen phthalate reagent, anisaldehyde-sulfuric acid reagent, and vanillin-sulfuric acid reagent for the detection of piperine and andrographide, the active constituents present in formulations like Tefroliv Forte tablets. Other constituents (tannins etc) were analyzed by UV spectrophotometry.
Abstract No. C-453, 61st IPC (2009). Fingerprint analysis of budmunchiamines, the main constituents in Albizia amara. Dried powdered leaves were extracted with petroleum ether (60-80 °C), chloroform, ethyl acetate and 90 % methanol by maceration for 48 h. TLC on silica gel with chloroform - methanol 19:1. Zones 2, 4 and 8 corresponded to the marcocylic alkaloids budmunchiamine A, B, and C, which was confirmed by FTIR, NMR and MS.
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.
J. Planar Chromatogr. 23, 289-292 (2010). HPTLC of oleanolic acid on silica gel pre-washed with methanol and acetone using toluene - ethyl acetate - formic acid 9:1:2 in a twin-trough chamber saturated for 30 min. Detection by spraying with 10 % sulfuric acid in ethanol, followed by heating at 130 °C for 3 min. Quantitative determination by densitometry at 490 nm. Linearity was between 600 and 1000 ng/band; the correlation coefficient was 0.994. The limit of detection and quantification was 27 and 82 ng/band. The repeatability (%RSD, n = 6) was 0.61 %, and the recovery was between 97.8 and 99.2 %. The inter-day and intra-day precision (RSD, n = 3) was 1.25 and 0.83 % (600 ng/band), 1.00 and 1.03 % (800 ng/band), and 1.11 and 0.81 % (1000 ng/band).
Journal of Pharmacy Research 2(12), 1893-1899 (2009). HPTLC of vasicine and vasicinone in methanolic aqueous extracts of the dried herb and in cough syrup on silica gel with chloroform - methanol 9:1. The hRf value of vasicine was 11 and of vasicinone 45. Densitometric quantification at 280 nm. The method was linear in the range of 2-100 ng/band for vasicine and 25-1000 ng/band for vasicinone. The recovery was 95-102 %. The limit of detection of vasicine was 1 ng and of vasicinone 25 ng. Vasicine and vasicinone were well separated from other constituents of Adhatoda vasica.
International Journal of ChemTech Research 2(2), 807-812 (2010). Chloroform and ethyl acetate extracts of leaves and bark of Ficus mollis (Moraceae) were subjected to TLC fingerprint profiling on silica gel with toluene - ethyl acetate - formic acid 16:2:1. Evaluation under UV 254 nm. Derivatization with vanillin-sulfuric acid reagent, followed by heating at 105 °C until colorization. In the bark 7 well-defined zones were observed, whereas in leaves 10 zones were observed. Heavy metal and mineral analysis was performed by atomic absorption spectroscopy.
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.
