Planta Med. 84(18), 1348-1354 (2018). A subfraction (obtained through liquid-liquid partition and column chromatography) of the ethanolic extract of whole Vernonia cinerea plants (Asteraceae, subf. Cichorioideae) was further fractioned by reverse-phase SPE (solid-phase extraction) followed by preparative TLC on silica gel layer (eluent not given). For verification, zones were detected by spraying with anisaldehyde solution with 10 % sulfuric acid, followed by heating at 100 °C. Further purification by reverse-phase HPLC allowed the isolation of 6 hirsutinolide-type sesquiterpenoids (all with a oxacyclonane forming an ether bridge), including vernolides A and B.
Planta Med. 84(18), 1340-1347 (2018). Preparative TLC on silica gel for the final purification of 15 phenylethyl-chromenone derivatives (including 3 with epoxide functions), 4 sesquiterpenoids (neopetasane, dehydrokaranone, dioxoselinene, ligudicin C) and a steroid (ergostatetraenone), all isolated through multi-step column chromatography from the ethyl-acetate fraction of a methanolic extract of Aquilaria sinensis resinous wood (Thymelaeaceae). For each compound, mobile phase, RF value and yield are given.
J. Chinese Trad. Patent Med. 41 (3), 516-521 (2019). Yiqi Tongmai Capsule is a herbal TCM for activating blood circulation and regulating veins, as to relieve dizziness, chest tightness, chest pain caused by blood stasis. HPTLC for quality control on silica gel (1) for Ligusticum chuanxiong hort, with n-hexane - ethyl acetate 3:1 after presaturation of plates for 20 min, detection under UV 366 nm; (2) for Radix paeoniae rubra, with chloroform - ethyl acetate - methanol - formic acid 80:10:40:1 after presaturation of plates for 20 min, detection by spraying with 5 % vanilline in sulfuric acid - ethanol 1:4 and heating at 105 ˚C until the zones are detected in daylight, comparison with the standard paeoniflorin; (3) for Panacis Quinquefolii Radix and Panaxnotoginseng (Burk.) F.H.Chen with trichloroform - anhydrous ethanol - water 10:10:1 after presaturation of plates for 15 min, detection by spraying with 10 % solution of sulfuric acid - ethanol 1:4 and heating at 105 ˚C until the zones are detected in daylight and under UV 366 nm, identification by comparison with the standards notoginsenoside R1, ginsenoside Rg1, Re, Rb1 and pseudoginsenoside F11.
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 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.
