Chinese J. Ethnopharm.(9), 36-38 (2012). Luman-12 is a traditional Mongolian herbal medicine preparation for treatment of cough, asthma, etc. For quality control of the main component herbal drugs TLC on silica gel 1) for Radix Polygalae, with toluene – ethyl acetate – formic acid 28:8:1, detection by spraying with 10 % sulfuric acid in ethanol and heating at 105 °C, viewing in daylight; 2) for Radix Glycyrrhizae, with toluene – ethyl acetate – formic acid 10:8:1, detection under UV 366 nm; 3) for Piper nigrum, with benzene – ethyl acetate – acetone 7:2:1, detection by spraying with 10 % sulfuric acid in ethanol and heating at 105 °C, viewing in daylight.
CBS 107, 11-12 (2011) HPTLC of tiliroside (a cosmetic active obtained by extraction from a plant of the family Sterculiaceae) and side components kaempferol-3-glucoside, kaempferol-3-rutinoside, kaempferol, and coumaric acid on silica gel with ethyl acetate - formic acid - acetic acid- water 100:11:11:27 + 1% heptane. Detection under UV 366 nm after spraying with natural products reagent (1 % diphenylborinic acid 2-aminoethylester in methanol) and under white light after spraying with anisaldehyde sulfuric acid reagent (0.5 mL anisaldehyde in 85 mL methanol with 10 mL acetic acid and 8 mL conc. sulfuric acid) and heating at 90-125 °C for 15 min. Quantitative absorption measurement of tiliroside at 315 nm using a 4-point calibration via peak area. The tiliroside contents in the sample extracts were determined as: 1 = 1.09 µg (RSD = 0.4 %), 2 = 0.93 µg (RSD = 0.8 %), 3 = 1.19 µg (RSD = 1.2 %) and 4 = 3.32 µg (RSD = 0.3 %). During the side component analysis no kaempferol, coumaric acid, and glucose were detected in the tiliroside samples. Small amounts of kaempferol-3-glucoside and kaempferol-3-rutinoside were found. HPTLC covers several tasks: quantification of the active ingredient in a complex plant matrix for determining the quality of the raw material, in-process control for monitoring the impurity profile during the manufacturing process and the quantification of the active ingredient in the final product.
Acta of Trad. Chinese Med. & Pharm. 40 (3), 100-102 (2012). Ruxian pills are a herbal TCM for treatment of abdominal mass accumulation and breast tumors etc. The medicine is prepared by blending the decoction and powders of the component drugs with honey in proper proportion and then processing into pills. For quality control, TLC on silica gel 1) for Radix Angelicae Sinensis, with n-hexane – ethyl acetate 9:1, detection under UV 366 nm; 2) for Radix Paeoniae Rubra, with chloroform – ethyl acetate – methanol – water 200:25:50:1, detection by spraying with 5 % vanillin in sulfuric acid – ethanol 1:25 and heating at 105 °C, viewing in daylight; 3) for Spina gleditsiae, with toluene – ethyl acetate – formic acid 7:2:1, detection under UV 366 nm. Using this method the optimum extraction conditions for preparing the decoction from the crude drugs as well as the stability during storage of the final preparation were studied.
by thin-layer chromatography) (Chinese). J. of Guizhou Normal Univ. (Natural Sci.) 30 (3), 9-11 (2012). Emilia sonchifolia (Linn.) DC. is a TCM herb used in the formulations for treating conjunctivitis, tonsillitis, pneumonia, infectious hepatitis, dysentery, diarrhea, urinary tract infection, etc. For quality control TLC of the herb extracts an the standard emodin on silica gel with chloroform – methanol – formic acid 300:10:1, detection 1) under UV 366 nm; 2) by exposing to ammonia vapors and viewing under UV 366 nm.
J. Planar Chromatogr. 26, 289-293 (2013). TLC of guaianolides and four other types of sesquiterpenoids, namely germacranolides, seco-pseudoguaianolides, and pseudoguaianolides, as well as two phytoecdysteroids in the aerial parts of Centaurea bella, Dugaldia hoopesii, Inula aschersoniana, Serratula wolffii, Stizolophus balsamita and Zoegea baldschuanica on silica gel with mixtures of methylene chloride and acetone in ratios 8:1, 7:1, 5:1, 3:1, 2:1 and 1:1 for sesquiterpenes and methylene chloride - acetone 1:2 as well as methylene chloride - methanol 5:1 for the separation of ecdysones. Detection by spraying with anisaldehyde reagent (anisaldehyde 0.5 mL; acetic acid 10 mL; methanol 85 mL; sulfuric acid 4.5 mL), followed by heating at 103 ºC for 3 min. The color evaluation allowed for correlation with the presence of substituents on the sesquiterpene ring with high probability.
Chinese J. of Ethnomed. & Ethnopharm. 20, 30-32 (2012). Inula nervosa Wall is a herbal TCM drug with anti rheumatism effects. It is frequently used as key component in herbal TCM preparations for the treatment of rheumatism. For quality control, TLC of the volatile oil (obtained by steam distillation of the crude drug) diluted 1:100 with acetone, and the standards thymol and thymyl isobutyrate, on homemade layers (coated using a slurry of silica gel in 1 % NaOH solution), with cyclohexane – toluene 3:4, detection by spraying with 5 % vanillin in sulfuric acid – ethanol 1:200 and heating at 105 °C until the zones are visible in daylight.
