The hRF values for (1) and (2) were 53 and 49, respectively.
Planta Medica 82, 09/10, 888-896 (2016). Preparative TLC on silica gel 1) to purify wortmin (from the sclerotiorin group of metabolites) from an apolar fraction of an ethyl acetate extract of Talaromyces tratensis KUFA 0091, developed with chloroform – petroleum ether – ethyl acetate 8:1:1; 2) to isolate tratenopyrone (new isocoumarin derivative) from a subfraction of the same extract, developed with chloroform – acetone – formic acid 10:10:1; 3) to isolate circinophoric acid (new diphenyl ether derivative) from a fraction of an ethyl acetate extract of Sporidesmium circinophorum KUFA 0043, developed with chloroform – acetone – formic acid 60:40:1. The yields calculated from the raw extracts were 512 ppm, 406 ppm and 224 ppm, respectively.
Planta Medica 82, 09/10, 903-909 (2016). To monitor the sorbent phase purification of a chloroform subfraction of the sponge Myxilla incrustans, TLC of fractions on silica gel with dichloromethane – methanol – formic acid 900:100:1, detection with Dragendorff’s reagent. The four positive fractions were purified by preparative HPLC, yielding three new N-acyl dopamine/dehydrotyrosine glycosides: myxillins A, B and C._x000D_

Sisheng Keli granule is a herbal TCM preparation for treating hematemesis, hematuria, allergic purpura and thrombocytopenic purpura, etc. For quality control, TLC on silica gel (1) for Artemisia argyi Levl. et Vant., with petroleum ether (60-90 °C) – toluene – acetone 20:16:1, detection by spraying with 1 % vanillin in sulfuric acid – ethanol 1:4 and heating at 105 °C until the zones are visible; (2) for Platycladus orientalis (L.) Franco, with toluene – ethyl acetate – formic acid 5:2:1, detection by spraying with 1 % aluminium trichloride in ethanol and detection under UV 366 nm; (3) for Lotus leaf, with chloroform – acetone – 10 % ammonia in ethanol 60:20:1, detection by spraying with 5 % potassium bismuthate solution and heating at 105 °C until the zones are visible. Quantification of nuciferin and verbascoside by HPLC.
Inula cappa roots
J. Planar Chromatogr. 29, 336-340 (2016). HPTLC of isoalantolactone (1), germacranolide (2), β-sitosterol (3), and lupeol (4) in the roots of Inula cappa on silica gel with toluene ‒ methanol 47:3. Detection by dipping into anisaldehyde reagent followed by heating at 105 ºC until colored bands appeared. Quantitative determination by absorbance measurement at 525 nm. Linearity ranged from 10-70 μg/mL for (1), 10-60 μg/mL for (2), 8-48 μg/mL for (3) and 15-90 μg/mL for (4). The intermediate precisions were below 0.9 % (n=7). The LODs and LOQs were 5 and 10 μg/mL for (1), (2) and (4) and 2 and 6 μg/mL for (3). Average recoveries were between 98.3 and 99.0 % for (1) to (4).
J. Ethnopharmacol. 195, 10-19 (2017).
