J. of Chromatogr. Sci. 58 (5), 411 - 417 (2020). Analysis of a binary mixture of silymarin (SR) and vitamin E (VE) acetate in their pure forms, pharmaceutical formulation and spiked human plasma, by HPTLC on silica gel with hexane - acetone - formic acid 140:60:3, detection at UV 215 nm, and quantification by densitometry. The linearity was 0.2 - 2.5 and 0.2 - 4.5 μg/band for SR and VE, respectively. Accuracy was 99.9 ± 1.2 % and 100.2 ± 1.6 % for SR and VE, respectively. The method was successfullly used for the determination of the studied drugs in their pharmaceutical formulation without any interference from excipients, and in spiked plasma samples. Statistical comparison of the results obtained by this HPTLC method showed no significant difference to the results obtained by the reported HPLC method.
J. Chinese Trad. Patent Med. 41 (7), 1728-1731 (2019). Sarcandra glabra (Thunb.) Nakai is a component herbal TCM drug with anti-bacteria, anti-inflammation, and anti-tumor activity. For quality control, TLC on silica gel at 25 % relative humidity and 21 °C with (A) toluene - ethyl acetate - formic acid 9:4:1, (B) cyclohexane - ethyl acetate - formic acid 7:6:1, (C) cyclohexane - ethyl acetate - formic acid 4:5:1. Detection (A) at UV 366 nm, (B) by exposure to ammonia vapor for 10 min and evaluation at UV 366 nm. Identification and assessment by comparison of the fingerprints with standards isofraxidin and rosmarinic acid. The method was successfully used for the analysis of 13 batches of real life samples.
Planta Med. 84(16), 1174-1182 (2018). The fractionation and purification steps (column chromatography, including reverse-phase HPLC) of an ethanolic extract of Millettia pinnata (= Pongomia pinnata, Fabaceae) roots were monitored by TLC on silica gel with n-hexane – ethyl acetate mixtures 4:1 - 2:1. Detection at 254 and 336 nm, and by spraying with sulfuric vanillin reagent followed by heating. The process allowed the isolation of 2 flavanols (including pongaflavanol), 1 flavanol ether and 26 flavanones (including derrivanone, griffinones, isoderricines, isoglabrachromene, isolonchocarpin, liquiritigenin, maxima flavanone A, ovalichromene B, ovaliflavanones, pinostrobin, pongachin, pongamone C, ponganone III).
Planta Med. 84(12-13), 941-946 (2018). The activity-guided fractionation and purification steps (column chromatography and liquid-liquid partitions) of a hydromethanolic extract of Alchemilla vulgaris aerial parts (Rosaceae) were monitored by TLC on silica gel with ethyl acetate – acetic acid – formic acid – water 100:11:11:27. Detection at 254 and 336 nm, and by spraying with anisaldehyde reagent followed by heating. A flavonoid (quercetin-glucuronide) was isolated through this process.
Planta Med. 84(12-13), 935-940 (2018). Atropine sulfate was hydrolyzed into tropine in a bath of barium hydroxide 8% (temperature 75°C, time 16h). For verification, an aliquot of the final solution was extracted into dichloromethane, which was applied, as well as alkaloid standards, on TLC silica gel and eluted with dichloromethane – ethanol – triethylamine 46:46:1. The reaction was confirmed as complete.
Planta Medica 84(12-13), 902-912 (2018). A dichloromethane extract of Athrixia phyllicoides aerial parts (Asteraceae) was eluted on a silica gel column with different mixtures of ethyl acetate and hexane or methanol. This fractionation was monitored on TLC silica gel layers, using the combinations of the same solvents as mobile phases. Detection by derivatization with Natural Product Reagent and PEG, and visualization at UV 254 nm. This allowed the grouping of the fractions into 13 profiles and the isolation of three hydroxy-methoxyflavones and a coumarate.
J. Planar Chromatogr. 33, 281-291 (2020). HPTLC of Weikangling capsules (a Chinese patent medicine for treating chronic gastritis, containing Paeoniae Radix Alba, Glycyrrhizae Radix et Rhizoma, Bletillae Rhizoma, Notoginseng Radix et Rhizoma, Poria, Corydalis Rhizoma, Sepiae Endoconcha, and Belladonnae Extractum) on silica gel with chloroform - methanol - water 14:5:1. Detection by spraying with 10 % sulfuric acid in alcohol, followed by heating at 105 ºC for 5 min. Qualitative analysis at UV 366 nm.
J. Planar Chromatogr. 33, 439-448 (2020). HPTLC fingerprint of 182 samples of Sclerocarya birrea and traditional medicines on silica gel with ethyl acetate - formic acid - water 8:1:1. Detection by heating at 100 ºC for 3 min, following by cooling and derivatization with natural products reagent (1.0 g of 2-aminoethyl diphenylborinate in 100 mL of methanol) and subsequently with anisaldehyde reagent (170 mL of ice-cooled methanol with 20 mL of acetic acid, 10 mL of sulfuric acid, and 1 mL of anisaldehyde), and heating at 100 ºC for 3 min. Quantitative determination of quercetin-3-O-rhamnoside by absorbance measurement at 254 nm.
