Chinese J. Trad. Pat. Med. (Zhongchengyao) 26 (8), Append. 9-11 (2004). TLC on silica gel previously immersed in 0.5 % NaOH solution, developed with 1) ethyl acetate - methanol - water 100:17:13; and 2) with the upper phase of toluene - ethyl acetate - formic acid - water 20:10:1:1. Detection by spraying with AlCl3 solution and under UV 365 nm. Identification by fingerprint technique and comparison with the standard. Quantification of scutellarin by HPLC.
J. Planar Chromatogr. 18, 269-273 (2005). HPTLC of flavonoids (hyperoside, isoquercitrin, luteolin, luteolin 7-O glucoside, rutin, vitexin, quercetin, quercitrin as standards) and phenolic acids (caffeic and chlorogenic acid) on silica gel after presaturation with ethyl acetate - acetic acid - formic acid - water 100:11:11:26. Detection by spraying with natural products reagent, followed by spraying with PEG. Visualization under UV light at 254 and 366 nm. Quantitative evaluation by video-densitometry.
leaf powder by high-performance thin-layer chromatography. J. Planar Chromatogr. 18, 305-307 (2005). HPTLC of methanolic extracts of Cinnnamomum tamala leaves and eugenol on silica gel with toluene - ethyl acetate - formic acid 90:10:0.1. Detection and quantitation by densitometry at 280 nm.
J. Pharm. Biomed. Anal 39, 132-138 (2005). A simple, selective, precise and stability-indicating HPTLC method of analysis of curcumin both as a bulk drug and in formulations was developed and validated. HPTLC on silica gel with chloroform-methanol 37:3. This system was found to give compact spots of curcumin (Rf 0.48). Densitometric analysis of curcumin in the absorbance mode at 430 nm. The linear regression analysis data for the calibration plots showed good linear relationship with r =0.996 and 0.994 via peak height and peak area, respectively, in the concentration range of 50-300 ng per spot. The method was validated for precision, recovery, robustness. The LOD and LOQ were 8 and 25 ng per spot, respectively. Curcumin was subjected to acid and alkali hydrolysis, oxidation and photodegradation.
Planta Med. 71, 54-58 (2005). Preparative TLC of microphyllaquinone and (1aS*,1bS*,7aS*,8aS*)-4,5-dimethoxy-1a,7a-dimethyl-1,1a,1b,2,7,7a,8,8a-octahydrocyclopropa[3,4]cyclopenta[1,2-b]naphthalene-3,6-dione on silica gel with hexane - ethyl acetate 7:3 and dichloromethane - chloroform 7:3. Detection under UV light at 250 nm and by spraying with a solution of vanillin - perchloric acid - ethanol, followed by heating at 100 °C for 5 min.
Planta Med. 70, 551-555 (2004). Analytical TLC of withaphysalin F and two new epimeric withaphysalins ((17S,20R,22R)-5beta,6beta:18,20-diepoxy-4beta,18-dihydroxy-1-oxo-witha-24-enolide (18R and 18S)) on silica gel with chloroform - ethyl acetate 3:7. Detection by spraying with 10 % sulfuric acid in ethanol, followed by heating at 120 °C for 5 min (orange spots).
Planta Med. 70, 1011-1014 (2004). TLC bioautography of bellidin, bellidifolin and the respective glucosides on silica gel with chloroform - methanol - water 50:10:1 with huperzine A, galanthamin HBr, and physostigmine as reference substances.
Planta Med. 71, 412-415 (2005). TLC of kaempferol 3-O-alpha-L-[2-(Z)-p-coumaroyl-4-(E)-p-coumaroyl]rhamnopyranoside and kaempferol 3-O-alpha-L-[2,4-di-(E)-p-coumaroyl]rhamnopyranoside on silica gel with dichloromethane - methanol 6:1. Observation under UV light at 254 nm and dipping in vanillin - sulfuric acid resulting in yellow-green spots.
