HPTLC of glycyrrhetinic acid and piperine in haematinic herbomineral capsule formulation on silica gel with toluene - ethyl acetate - glacial acetic acid 25:15:1. Quantitative determination by absorbance measurement at UV 254 nm. The method was linear in the range of 0.8-2.4 ng/spot (glycyrrhetinic acid) and 10-50 ng/spot (piperine). Recovery was 96.3-98.6 %.
J. Planar Chromatogr. 22, 377-380 (2009). HPTLC of stigmast-5-en-3beta-O-D-glucoside and bark extracts on silica gel with chloroform - methanol - water 33:7:4 in a saturated twin trough chamber. Detection by derivatization with anisaldehyde reagent followed by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 515 nm.
Learned J. Dali Acad. (General Issue) 8 (10), 3-6 (2009). TLC of puerarin (in extracts obtained from different parts of Radix Puerariae) on silica gel with trichloromethane – methanol – water 14:5:1. Detection under UV 254 nm. The maximum amount of puerarin was found in the bine of the drug, followed by that in the root, whereas no puerarin was found in the flower and fruit.
Ind. J. Pharma. Science 71 61, 656-662 (2009). Medicated oils prepared both by Ayurvedic as well as modified process were evaluated for fingerprint profiling by HPLC and HPTLC. HPTLC of methanolic extracts of the oils on silica gel with chloroform methanol 9:1 and toluene - ethyl acetate 4:1 for general fingerprint profiling; with toluene - ethyl acetate - formic acid 5:4:1 for flavonoids and with toluene - ethyl acetate - diethyl amine 7:2:1 for alkaloids. Evaluation under 254 nm and 365 nm. Detection by treatment with NP-PEG reagent for flavonoids and Dragendorff reagent for alkaloids.
Chinese J. Chromatogr. 26 (1), 50-55 (2008). TLC of some endophytic fungi isolated by column chromatography from selected medicinal plants on silica gel plates with 1) chloroform - methanol 7:1, 2) chloroform - acetonitrile 7:3, 3) ethyl acetate - 2-propanol 19:1, 4) methylene chloride - tetrahydrofuran 3:1, 5) methylene chloride - methanol - dimethylformamide 90:9:1. Detection by spraying with 1 % vanillin sulfuric acid reagent after gentle heating. Also HPTLC on silica gel with chloroform - methanol 9:1. Detection by densitometry at 254 nm and 366 nm. If taxol was present, derivatization by spraying with 1 % vanillin sulfuric acid reagent and heating for 2 min, then detection under UV 366 nm and white light. Only 13 fungal species produced taxol in the artificial culture medium of the 20 screened fungi.
Modern J. of Integrated Trad. Chinese & Western Med. 19(31), 3439-3441 (2010). TLC on silica gel with chloroform – methanol – water 13:7:2. Detection by spraying with 10 % slfuric acid in ethanol and heating at 105 °C until the zones are visualized, evaluation under UV 366 nm. Identification of the component drugs Radix Astragali and Rhizoma Chuanxiong P.E by comparison of the retention values and color of the zones by the active compounds astragaloside and ferulic acid in the individual drug.
J. of Guangzhou Chem. Engin. 39(1), 144-145 (2011). A course on the technology of TLC/bioautography applied for the analysis of TCM was set-up to enhance students’ understanding of theoretical knowledge and to train and improve the interest and skill of students in chemical experiments. Demonstration of the TLC analysis of rutin and quercetin in Flos Sophorae on silica gel with ethyl acetate – formic acid – water 8:1:1. Detection under UV 254 nm and 366 nm, and by immersing into a solution of 1,1-diphenyl-2-picrylhydrazyl in ethanol (DPPH radical reagent). The result of this practice was satisfactory, and the course proved to be a good example to utilize the modern technology in the experimental teaching.
J. Planar Chromatogr. 24, 394-399 (2011). TLC of leave extracts and six flavonoids as markers (vitexin, isovitexin, orientin, isoorientin, quercetin, and tricin) on silica gel, prewashed with methanol and methylene chloride, with methanol - ethyl acetate - acetone - methylene chloride in different ratios using automated multiple development. The developed plate was dried in air for 2 h and sprayed with 1 % aluminum trichloride in ethanol. Then the plate was left for 2 h for derivatization in a glass drying chamber. Quantitative determination by densitometry at 366 nm. The hRf values of the six marker flavonoids were 22, 31, 38, 45, 57, and 88, respectively. Linearity was between 175 and 1750 ng/band. Instrument precision (n = 10) was between 0.2-0.9 %. The repeatability for standards and samples (n = 9), was 0.7 and 0.5, 0.8 and 0.5, 0.8 and 0.5, 0.8 and 0.4, 1.3 and 0.7, 1.1 and 0.3 % for isoorientin, orientin, isovitexin, vitexin, quercetin, and tricin, respectively. The limits of detection were 35, 40, 35, 50, 80, and 20 ng/zone for isoorientin, orientin, isovitexin, vitexin, quercetin, and tricin, respectively. The intra-day and inter-day precision was between 0.1-2.9 % and 0.3-2.4 % for all six marker flavonoids.
