Chinese J. of Lishizhen Trad. Med. & Pharm. 22 (4), 860-862 (2011). Fallopia multiflora (Thunb.) Harald, a medicinal herbal drug widely applied in traditional Chinese medicines, is available from different provinces of China. Presentation of fingerprint methods of Fallopia multiflora from different regions by micellar thin-layer chromatography (MTLC) and IR techniques. MTLC of methanol extracts of Fallopia multiflora and emodin standard solution on polyamide layer with 0.4 % cetylpyridinium chloride in acetone – methanol – 1.0 mol/L NaOH 12:4:5 after chamber saturation for 15 min. Detection of the purple zones in daylight. The ratio of the hRf values of the component zones and those of emodin was calculated. In addition, FTIR of the methanolic extracts and emodin standard solution mixed in KBr tablets. The results of the real life samples available from five different regions are given and proved that the method is suitable for the quality control of the drugs.

J. Chromatogr. A 1260, 232-238 (2012). Presentation of a new RP-HPTLC method for the separation of pyrazinamide, isoniazid, rifampicin and ethambutol in a four fixed-dose combination tablet formulation by detection of pyrazinamide, isoniazid and rifampicin at UV 280 nm firstly, and then derivatization and detection of ethambutol at 450 nm after RP-plate development. Evaluation of methanol, ethanol and propan-1-ol as the modifiers to form alcohol-water mobile phases. Systematic optimization of the composition of each alcohol in the mobile phase by using the window diagramming concept to obtain the best separation. Examination of the Rf distribution of the separated compounds indicated that separation of the compounds with the mobile phase containing ethanol at the optimal fraction situated within the optimal hRf-values region of 20-80, thus ethanol was selected as the organic modifier and the optimal mobile phase composition was found to be ethanol – water - glacial acetic acid - 37 % ammonia 70:30:5:1.
