J. Planar Chromatogr. 24, 400-405 (2011). TLC of plant extracts and kaempferol, quercetin, and rutin as standards on silica gel with ethyl acetate - formic acid - acetic acid - water 100:11:11:27 with chamber saturation for 30 min. Detection by spraying with 1 % methanolic diphenylborinic acid 2-aminoethylester followed by 5 % ethanolic polyethylene glycol 4000. Evaluation under UV 366 nm. Detection of the antioxidant activity with DPPH radical reagent. Videodensitometric analysis of the derivatized TLC plates. The hRf value was 24 for rutin, 98 for quercetin and 100 for kaempferol.

PHCOGJ 2(11), 374-380 (2010). Root bark of Alangium salvifolium (Linn.f.) Wang is a reputed drug mentioned in the ancient books of Ayurveda and Siddha for the treatment of epilepsy, jaundice, hepatitis etc. TLC of ethanolic, chloroform, and ethyl acetate extracts of the root bark of Alangium salvifolium on silica gel with toluene - ethyl acetate - diethylamine 10:7:1. Evaluation under UV 254 nm and 366 nm.

extracts on polar-bonded stationary phases. J. of Chromatogr. A 1218 (19), 2812-2819 (2011). Two-dimensional TLC of phenolic compounds (extracted from Polygonum hydropiper L. and Polygonum cuspidatum L.) on cyano phase with non-aqueous solvents in the first direction and aqueous solvents in the second direction. For the separation of standards the optimal chromatographic systems was determined based on the retention data collected in one-dimensional TLC experiments by plotting graphs of Rf vs. Rf dependencies.

J. Planar Chromatogr. 24, 130-135 (2011). TLC of Juniperus essential oils (containing terpenoids, monoterpenes, sesquiterpenes and alcohols) with guaiazulene and cineole as standards on silica gel with ethyl acetate - toluene 1:19. Detection by spraying with anisaldehyde reagent followed by heating for 5 min at 100 °C and examination under daylight. The hRf values were 42 and 89 for cineole and guaiazulene, respectively.

J. Planar Chromatogr. 25, 504-508 (2012). Physical properties of polar and non-polar solvents under electric current pulse were studied. In addition, solvents were classified according to their behavior in a pulsating electric field with applications in planar dielectrochromatography.

J. Trad. Chinese Med. & Pharm. Consult. 3 (7), 368-369 (2011). Hormones have been widely applied in clinical practice, however, overdose hormones are liable to cause general anaphylaxis, and even serious harm to physical health. For quick identification of hormones in traditional Chinese preparations, TLC of the extracts of the preparations on silica gel with chloroform – petroleum ether (30-60 ºC) – methanol 5:3:1, detection at UV 254 nm. Identification of methyltestosterone, prednisolone acetate, estrone, ethinyloestradiol, prednisolone acetate, testosterone undecanoate, fluocinolone acetonide, dexamethasone, betamethasone sodium phosphate, and hydrocortisone acetate by fingerprint comparison with the standards. The method has been applied to the real life samples of four varieties of preparation. The results were compatible with those obtained by HPLC and MS-MS.

J. of China Pharm. 21 (10), 31-32 (2012). Chuanyushaoshang cream is a herbal TCM preparation for external application for protecting wounds, promoting wound healing, antibiosis, invigorating the circulation of blood, and relieving pain. For quality control, TLC of emodin, one of the key active constituents in the extracts of the preparations, on silica gel with petroleum ether (60-90 ºC) – ethyl acetate 7:3, detection at UV 366 nm.

J. of Yangtze Univ. (Nat. Sci., Med.) 9 (1), 64-65 (2012) . Angelica sinensis is a herbal TCM drug widely used in the preparations for gynaecological diseases, effective in promoting blood circulation, ease of pain and against inflammations. TLC of the extracts of the preparation on silica gel with n-hexane – ethyl acetate 9:1. Detection under UV 366 nm.
