J. Planar Chromatogr. 28, 213-217 (2015). HPTLC of (1) chlorogenic acid, (2) caffeic acid, (3) faradiol and (4) rutin from Calendula officinalis plant extracts on silica gel previously activated at 50 °C in an oven for 30 min. Automated multiple development (gradient elution) with n-hexane, ethyl acetate containing 2 % acetic acid, and water as mobile phase. Detection by spraying with either 10 % sulfuric acid in methanol or 2-aminoethyl diphenylborinate solution followed by placing in oven at 50 °C for 30 min. (1), (2), (3), and (4) were used as markers to investigate and assess the quantitative errors observed. Accuracy of the sample applicator at different sample volumes, the use of a gradient mobile phase, and post-derivatization contribute to uncertainties of the HPTLC method and need to be carefully selected to minimize errors.
J. Planar Chromatogr. 28, 398-401 (2015). TLC of pirfenidone in tablet formulation on silica gel with toluene - methanol 4:1. Quantitative determination by absorbance measurement at 315 nm. The hRF value for pirfenidone was 49. Linearity was in the range of 800-1600 ng/zone. LOD and LOQ were 0.550 and 1.667 ng/zone. The intermediate precision was below 1.8 % (n=3). Recovery ranged between 100 and 102 %.
Chinese J. of Med. Guide 12 (10), 8-10 (2014). Huayu Tongluo Jianpan Tie plaster is coated with a herbal TCM preparation for the treatment of pain and numbness in the neck, waist, upper limbs and legs caused by the protrusion of cervical and lumbar intervertebral discs. For quality control, TLC on silica gel (1) for Boswellia carterii Birdw./Boswellia bhaurdajiana Birdw. Resin, with petroleum ether (60-90 °C) – ethyl acetate 5:1, detection by spraying with 5 % vanillin in sulfuric acid – ethanol 1:4 and heating at 100 °C until the zones are visible in daylight; (2) for Commiphora myrrha Engl./Commiphora molmol Engl. resin, with chloroform – ethyl acetate 80:1, detection as before; (3) for Daemonorops draco Bl., with chloroform – methanol 19:1, detection in daylight. Quantification of dracorhodin by HPLC.
Planta Medica 82 (16), 1395-1402 (2016). The hexane – ethyl acetate subfraction of the ethyl acetate fraction of an ethanolic Tabebuia roseoalba leaf percolation extract was subfractioned on a silica gel column with 42500 mL of a gradient of hexane, ethyl acetate, and methanol. For monitoring, TLC on silica gel with hexane – ethyl acetate 1:1, detection with anisaldehyde sulfuric acid reagent. Two fractions that gave only one visible zone on TLC, were identified by NMR as mixtures of stigmasterol and sitosterol, and of alpha- and beta-amyrins, respectively.
Planta Medica 82(18), 1576-1583 (2016). The fractionation (by column and flash chromatography) of an aqueous extract of the aerial parts of Hilaria hirsuta was monitored through TLC on silica gel with n-butanol – acetic acid – water 13:3:5. The compounds (including flavonoids narcissin and rutin, and two new saponins, herniariasaponins G and H) were detected with anisaldehyde sulfuric acid reagent.
extracts employing multivariate chemometrics – a case study on Morus alba
Phytochem. Anal. 28, 125-131 (2017). HPTLC of the dried fractions of Morus alba wood on silica gel with dichloromethane – methanol 22:3, and to achieve better resolution for the high activity fractions with dichloromethane – methanol 83:17. Qualitative determination under UV 254 and 366 nm and detection with sulfuric acid reagent. Partial least squares-regression was performed to discover the substances that were most correlated to bioactivity.
Planta Medica 83(14/15), 1149-1158 (2017). The cyclodextrane fractionation of the methanolic percolate of Salix reticulata aerial parts was analyzed on silica gel with ethyl acetate – methanol – water 100:13:10. Detection by derivatization with vanillin-sulfuric acid reagent. Luteolin and apigenin glycosides, catechin, procyanidins and phenolic glucosides (picein, triandrin, and salicortin) were isolated from these fractions through preparative HPLC._x000D_
Pharm. Anal. (Yaowu Fenxi Zazhi) 5, 117-118 (1985). (Chinese) (Determination of yam sapogenins by TLC-densitometry.). TLC of sapogenins in yam tubers on silica with chloroform - acetone 97:3. Quantification by densitometry.
