(Chinese). Chinese J. Pharm. Anal. (Yaowu Fenxi Zazhi) 15, 56-60 (1995). A review with 46 references on the analysis of drugs for central nervous system by TLC as well as GLC and HPLC etc. Discussion of the developing solvent systems used and the detection limits obtained for several compounds as example. Comparison of the mentioned chromatographic methods.

Quantification by densitometry at 265 nm and 350 nm, respectively. Detection limits 1.6 and 0.8 µg, respectively. Precision 2.9% (n=5), 3.4% (n=5), respectively. Recovery 95.2 ± 3.4% (n=5), 96.9 ± 2.8% (n=5), respectively.

J. Chinese Trad. Patent Med. (Zhongchengyao) 20 (7), 3-5 (1998). TLC of percutaneously permeated samples on silica gel with butanol - acetic acid - water 4:4:1. Detection under UV 365 nm. Determination and evaluation of berberine content by comparison to standard. Comparison of the results to those obtained by HPLC.

J. Chinese Trad. & Herb. Drugs (Zhongcaoyao) 32 (3), 217-218 (2001). TLC on silica gel with butanol - acetic acid - ethanol - water 4:2:1:1. Detection by spraying with 0.5% ninhydrin in ethanol and heating at 110°C for 8 min. Quantitation by densitometry at 513 nm.

CBS 93, 2-4 (2004). HPTLC of signaling ceramides on silica gel with a 7 step gradient from methanol over dichloromethane to n-hexane over 42 min. Detection by dipping in manganese chloride reagent for 1 s, followed by drying at 120 °C for 20 min. Quantitative determination by absorbance measurement at 550 nm and Michaelis-Menten regression 2 via peak area. Signaling ceramides are separated from other lipids (shingomyelin, phosphatidylcholine, cholesterol) contained in cellular lipid extracts. Comparison with determination of ceramide formation via isotope labeled standards and conventional TLC method.

J. Planar Chromatogr. 28, 83-89 (2015). HPTLC of irbesartan in tablets and plasma on silica gel with acetonitrile - chloroform - glacial acetic acid 30:19:1. Detection by exposure to concentrated hydrochloric acid vapor for 10 min. Quantitative determination by fluorescene measurement at 255/>400 nm. The hRF value of irbesartan was 40. Linearity was between 7 and 90 ng/zone. The intermediate intra-day and inter-day precisions were below 2.8 % (n=6). The LOD and LOQ were 2 and 6 ng/zone, respectively. Recoveries were in the range of 96.9-98.6 % in tablets and 95.8-97.4 % in plasma.
