Chimonanthus nitens Oliv. is a plant of the Calycanthaceae family growing in Jiangxi and Anhui areas of China. Pharmacological studies showed that the chemical constituents of the extracts of its dry leaves are volatile oils, alkaloids, flavonoids, coumarins, etc. The dry leaves are used clinically as the main ingredient drug in TCM prescriptions for the treatment of infantile cough, respiratory tract infection, hand foot and mouth disease and chronic pelvic inflammatory disease, etc. For quality control, HPTLC of the sample extracts and the standards cineole, linalool and beta-caryophyllene on silica gel firstly with chloroform – methanol 9:1 to 5 cm and then with petroleum ether (30-60 °C) – ethyl acetate 10:1 to 10 cm, detection by spraying with 1 % vanillin in sulfuric acid – ethanol 1:4 and heating at 110 °C. Quantitative determination by densitometric evaluation at 606 nm for cineole and linalool and 545 nm for beta-caryophyllene using external standard calibration method. The content of the total unknown components is also given taking linalool as the calibration standard. Validation of the method by investigation of its linearity range (for cineole 0.7-11.4 µg/zone, r=0.990, n=7; for beta-caryophyllene 0.7-10.9 µg/zone, r=0.992, n=7; for linalool 1.8-18.0 µg/zone, r=0.990, n=7), precision (%RSD (n=6) 3.9 %, 1.5 % and 0.6 % for cineole, beta-caryophyllene and linalool, respectively), stability (within 30 min, %RSD (n=6) 2.0 %, 3.0 % and 3.3 % for cineole, beta-caryophyllene and linalool, respectively) and reproducibility (%RSD (n=6) 2.7 %, 4.4 % and 3.2 % for cineole, beta-caryophyllene and linalool, respectively). The recovery for cineole was 82.3-93.4 % (%RSD (n=3) 2.6-4.1 %), for beta-caryophyllene 86.1-96.7 % (%RSD (n=3) 2.2-3.6 %) and for linalool 95.8-109.8 % (%RSD (n=3) 1.9-2.9 %). Some unknown separated components need to be identified in a further study.

J. Planar Chromatogr. 27, 367-371 (2014). TLC of (±)-bupropion on silica gel impregnated with 2 mM Cu(II) and 4 mM L-amino acid 1:2, with acetonitrile - methanol - chloroform 2:1:2. Detection by exposure to iodine vapors. The Cu(II) acetate–amino acid complex allowed efficient enantiomer separations. Four different approaches for impregnating/loading the ligand exchange reagent were evaluated. However, using a solution of Cu(II) acetate as mobile phase additive for the TLC plates impregnated with one of the L-amino acids allowed the best enantiomer separation.
In. Arch. Otorhinolaryngol. 19, 141-150 (2015). HPTLC of the lipids lactosylceramide (1), triacylglycerol (2), phosphatidylcholine (3), cholesterol (4) and sphingomyelin (5) in mastoid tissue on silica gel with chloroform - methanol - water 65:25:4. Detection of lipids by spraying with orcinol reagent (0.02 % in 50 % sulfuric acid) followed by heating at 120 °C for 2-3 minutes. Additional detection with Coomassie Brilliant Blue (0.03 % in 30 % methanol/100 mM sodium chloride) followed by methanol 30 % in 100 mM sodium chloride for destaining. The hRF value was 24-47 for (1) and (5), 71-100 for (2) and (4), and 0-24 for (3). Combination with gas chromatography/electron impact-mass spectrometry revealed the presence of cholesterol and several fatty acids. Combination with flow-injection/electrospray ionization-tandem mass spectrometry revealed a host of phosphatidylcholines, phosphatidylethanolamines, and cholesteryl esters.
