J. AOAC Int. 91, 1174-1178 (2008). HPTLC of hederagenin on silica gel with toluene - ethyl acetate - formic acid 7:3:5 in a twin-trough chamber. Detection with anisaldehyde - sulfuric acid reagent by dipping for 1 s and heating for 7 min at 100 °C. Quantitative determination by absorbance measurement at 595 nm.
Abstract No. 0983, IHCB (2009). HPTLC of mahanimbine (a carbazole alkaloid isolated from Murraya koenigi) on silica gel with petroleum ether - chloroform 13:7. The hRf value of mahanimbine was 60. Quantitative determination by absorbance measurement at 254 nm. The method was linear in the concentration range of 50-250 ng/spot. Enzyme inhibition activity of methanol, petroleum ether, and chloroform exctracts of the plant and of mahanimbine was evaluated using galantamine as standard inhibitor of the enzyme.
J. Chinese Trad. Patent Med. 29 (4), 536-540 (2007). TLC of Yangxue Fuzheng (a traditional Chinese patent medicine) capsule extracts on silica gel with 1) chloroform - methanol - water 13:7:2, 2) chloroform - ethyl acetate - methanol - water 15:40:22:10, 3) ethyl acetate - butanone - methanol - water 10:1:1:1, 4) chloroform - methanol 40:3, 5) petroleum ether (60-90 ºC) - ethyl acetate 1:1. Detection 1) under UV 365 nm, 2) in daylight after spraying with 10 % sulfuric acid in ethanol and heating at 105 ºC.
J. AOAC Int. 92, 785-788 (2009). HPTLC of plant extracts and herbal preparations applied bandwise on silica gel with ethyl acetate - formic acid - acetic acid - water 100:11:11:25 after preconditioning for 5 min. Detection by immersion in natural products reagent (diphenylboric acid 2-aminoethylester) followed by polyethylene glycol 400 reagent for 2 s. After air-drying the plates were evaluated under UV 366 nm.
J. Chinese Trad. & Herb. Med. 39 (12), 1818-1829 (2008). TLC of the extracts of the TCM drug on silica gel with 1) chloroform - methanol - acetone - ammonia 2:1:4:4; 2) chloroform - methanol - acetone - formic acid 32:8:4:7; 3) ethyl acetate - butanone - formic acid - water 10:1:1:1; 4) chloroform - methanol - water 13:7:2. Detection by evaluation under UV 365 nm and after spraying with 1) potassium iodobismuthate reagent; 2) a 1:1 mixture of 1 % potassium ferricyanide and 1 % FeCl3; 3) by spraying with 10 % sulfuric acid in ethanol followed by heating at 105 °C until coloration.
International Seminar on Herbal Drug Research, PN-028 (2009). HPTLC of curcumin and 3-acetyl-11-keto-a-boswellic acid in the herbal product Rheumax (contains Curcuma longa, Boswellia serrata, Tinospora cordifolia and Vitex negundo) on silica gel with chloroform - methanol 37:3 for curcumin and n-hexane - ethyl acetate 1:1 for the acid. Quantitative determination by absorbance measurement at 430 nm for curcumin and 254 nm for the acid. The method was linear in the range of 100-500 ng/band for curcumin and 1500-4000 ng/band for the acid.
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.
Acta Chromatographica 22 (2), 227-236 (2010), DOI:10.1556/AChrom.22.2010.2.6. TLC of piperine, the bioactive constituent of black pepper (Piper nigrum), on silica gel with dichloromethane – ethyl acetate 9:1 at 30 °C in a twin-trough chamber saturated for 30 min. Detection under UV light at 254 nm and documentation with a digital camera. Based on the image a density profile plot was established by Scion Image software, which allowed to calculate the concentration of piperine by comparison of the peak areas of samples and piperine standards. The linearity was in the range of 24-84 ng/zone (r2=0.9927). The limits of detection and quantitation were 0.35 and 1.05 ng/zone, respectively. Precision (repeatability, n=6) and intermediate precision (2 days, n=12) both are below 2.6 %RSD. Recovery is between 96.7-101.4 %.
