Detection under UV light at 254 and 366 nm, and at 366 nm after spraying with 1.0 % methanolic diphenylborinic acid 2-aminoethylester.
J. Planar Chromatogr. 24, 352-356 (2011). HPTLC of extracts of dried powdered rhizoms of A. galanga and three phenylpropanoids (1-acetoxychavicol acetate (1), acetoxyeugenol acetate (2), and trans-p-coumaryl diacetate(3)) on silica gel with n-hexane - ethyl acetate 4:1 with chamber saturation for 1 h. After drying second development with the same mobile phase. Quantitative determination by densitometry at the wavelength of maximum absorption. Linearity was between 0.6-1.8 µg/band, 0.4-1.5 µg/band and 0.1-0.3 µg/band for (1), (2), and (3), respectively. The LOD and LOQ was 150 and 500 ng/band for (1), 100 and 334 ng/band for (2), and 23 and 77 ng/band for (3). The repeatability of application and repeatability of measurement (%RSD, n = 6) was 0.9 and 0.5 % for (1), 0.5 and 0.3 % for (2), and 1.8 and 0.9 % for (3). The intra-day and inter-day precision was below 5 % for all compounds. The hRf value was 53, 37, and 43 for (1), (2), and (3), respectively.
Planta Med. 75, 12-17 (2009). HPTLC of swertiamarin and the ethyl acetate extract of Enicostemma axillare on silica gel with ethyl acetate - butanol 1:1 in a twin trough chamber. Quantitative determination by densitometric absorbance measurement at 254 nm.
International Journal of Pharmacy and Pharmaceutical Sciences 3(2), 42-44 (2011). TLC of andrographolide in Andrographis paniculata (Kalmegh), collected from different Indian geographical sources, on silica gel with chloroform - methanol 7:1. The hRf value of andrographolide was 41. Densitometric quantification at 231 nm. The method was linear in the range of 100-500 ng/band. The amount of andrographolide varied from 0.7-1.2 % in samples collected from different geographical regions.
J. Planar Chromatogr. 24, 125-129 (2011). HPTLC of plant extracts and oxyresveratrol on silica gel, prewashed with methanol, with hexane - ethyl acetate - chloroform - methanol 15:10:17:8 in a twin-trough chamber lined with filter paper and saturated for 20 min. Quantitative determination by densitometry at 327 nm. LOD and LOQ were 50 and 200 ng/band, respectively. The hRf value of oxyresveratrol was 31. Intra-day and inter-day variation (%RSD) were consistently below 5.0 %. Within-day precisions for the replicate analysis (n = 3) were in the range of 1.1-4.1 %. Day-to-day replicates (n = 9) were between 2.1-2.8 %.
International Journal of PharmTech Research 2(4), 2438-2440 (2010). TLC of methanolic extracts of powdered dry fruits of Embelia ribes on silica gel with toluene - acetone - acetic acid 18:2:1. Detection with anisaldehyde-sulphuric acid reagent. The hRf values of the four major bands were 13, 27, 32, and 60.
Chinese J. Ethnomed. Ethnopharm. 23, 69-71 (2011). In recent years, some unauthorized specific medicines were available as “traditional cure”, “folk recipe”, or “ancestral folk prescription” in China, such as powders and pills for relieving cough or capsules for rheumatic arthritis. It has been found that certain kinds of steroid hormones were added. Description of a quick method for screening of prednisone acetate and dexamethasone acetate in the chloroform extracts of the popular medicines by TLC on silica gel with dichloromethane – diethyl ether – methanol – water 385:60:15:2. Detection by heating at 105 °C for 10 min followed by spraying with 2 % alkaline tetrazolium solution and viewing under daylight.
