J. Liq. Chromatogr. Relat. Technol. 39, 312-321 (2016). HPTLC of lupeol in waxes of different cabbage varieties on RP-18 with ethyl acetate – acetonitrile 5:1. Detection by dipping into the anisaldehyde reagent (16 mL sulfuric acid were dropwise added to a cooled mixture of 20 mL glacial acetic acid and 170 mL methanol, then 1 mL of anisaldehyde was added), followed by heating at 110 °C for 30 s. Quantitative determination by absorbance measurement at 535 nm. The hRF of lupeol was 40. Linearity was in the range of 30-150 ng/zone. The LOD and LOQ were 7 and 20 ng/zone, respectively. Intermediate precisions were below 10 %. Recoveries were between 90.3 and 93.1 %.
Chinese J. of Inform. on TCM 20 (7), 59-61 (2013). Shengxinfa Jiaonang capsule is a herbal TCM preparation for treatment of hair loss caused by blood deficiency and kidney essence deficiency, scalp pruritus, alopecia areata, and postpartum alopecia. For quality control, TLC on silica gel (1) for Fallopia multiflora (Thunb.) Harald, with toluene – ethyl acetate – formic acid 15:2:1, detection in daylight; (2) for Psoralea corylifolia Linn., with n-hexane – ethyl acetate 4:1, detection by spraying with 10 KOH in methanol and viewing under UV 366 nm; (3) for Gastrodia elata Bl., with chloroform – ethyl acetate 1:1, detection by spraying with 10 % sulfuric acid in ethanol and heating at 105 °C until the zones are visible. Quantification of 2,3,5,4'-tetrahydroxy stilbene-2-Ο-β-D-glucoside by HPLC.
J. Sep. Sci. 39, 4258-4262 (2016). TLC of 35 model compounds on RP-2, RP-8, RP-18, alumina, cellulose, cyano, diol, amino phase, and silica gel with 20 pure solvents (acetone, acetonitrile, 1-butanol, 1-chlorobutane, chloroform, cyclohexane, 1,2-dichloroethane, dichloromethane, dioxane, ethanol, ethyl acetate, heptane, hexane, methanol, isooctane, 1-propanol, 2-propanol, t-butyl methyl ketone, tetrahydrofuran, and toluene). Parallel factor analysis was used to study the retention phenomena in quantitative manner.
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.
J. Planar Chromatogr. 29, 462-468 (2016). HPTLC of dantrolene sodium (1) and its process-related impurity 5-(4-nitrophenyl)-2-furaldehyde (2) on silica gel with chloroform – ethyl acetate – glacial acetic acid 1000:500:1. Quantitative determination by absorbance measurement at 380 nm. The hRF values for (1) and (2) were 22 and 83, respectively. Linearity ranged between 100-1500 ng/zone for (1) and 100-2000 ng/zone for (2). The intermediate precisions were below 0.3 % (n=3). The LODs and LOQs were 33 and 99 ng/zone for (1) and 32 and 96 ng/zone for (2), respectively. Average recoveries were 99.5 % for (1) and 100.2 % for (2).
J. Liq. Chromatogr. Relat. Technol. 40, 259-281 (2017).
