J. Liq. Chromatogr. Relat. Technol. 35, 1141-1145 (2012). HPTLC of diosgenin in various parts of Tribulus terrestris L. on silica gel with toluene - ethyl acetate - methanol 7:3:1. Detection by dipping in anisaldehyde reagent consisting of anisaldehyde - acetic acid - sulfuric acid - methanol 1:20:10:170, followed by heating at 110 °C for 2 min. Quantitative determination by absorbance measurement at 430 nm. The hRf value of diosgenin was 48 and selectivity regarding matrix was given. Linearity was between 50 and 240 ng/zone. The method provides acceptable intra-day and inter-day precision for diosgenin. The limits of detection and quantification were 2 and 7 ng/spot, respectively. Recovery (by standard addition) was 100.6 %. The method provided comparable results with HPLC.

J. of China Pharm. 25 (8), 772-775 (2011). Safflower, the dried flower of Carthamus tinctorius L. is a herbal TCM drug for invigorating the circulation of blood, stimulating the menstrual flow, dissipating blood stasis, relieving pain, and is prescribed clinically to cure amenorrhea, falling injuries and skin and external diseases. Due to the lack of the source some counterfeits have been found on the market in recent years. The methods were studied for differentiating the dyes used by the market for adulteration of safflower. For dyes, TLC of the extracts of the crude drugs on silica gel firstly with chloroform – methanol – glacial acetic acid 7:1:2, detection under daylight for identification of orange, then with ethyl acetate – n-butanol – ethanol – ammonia – water 1:3:3:1:1, detection under daylight for identification of acid red 73, lemon yellow and carminum respectively. Results obtained by HPLC were compatible with those obtained by TLC.

Quantitative determination by absorbance measurement at 340 nm. Linearity was in the range of 150-450 µg/mL for (1) and 50-150 µg/mL for (2). The intermediate/inter-day/intra-day precision was below 2 %. Recovery was 99.5 % for (1) and 99.3 % for (2).
