Chromatographia 61 (5-6), 307-309 (2005). Similarities and differences between the retention characteristics of octadecyl silica gel wettable with water used in TLC and RP-18 used in HPLC have been elucidated by use of the linear relationships between log k and RM. The stationary phases compared were investigated with the same mobile phases - binary mixtures of methanol and water, acetonitrile and water, and tetrahydrofuran and water. For these adsorbents of the same type but differing in specific surface area the correlation line was shifted by log (alpha system I / alpha system II). High values of the correlation coefficients obtained over the whole range of mobile phase organic modifier concentration examined indicated that the TLC systems could be used to predict HPLC conditions for flavonoid separation.
J. Planar Chromatogr. 20, 317-320 (2007). HPTLC of mangiferin (a C-glucosyl xanthone) on silica gel with ethyl acetate - methanol - water - formic acid 20:2:2:1. Detection and quantification were performed densitometrically at 270 nm.
J. Planar Chromatogr. 26, 274-278 (2013). HPTLC of oroxylin A in Oroxylum indicum herbal formulations on silica gel with toluene - ethyl acetate - acetic acid 14:5:1. Quantitative determination by absorbance measurement at 275 nm. The hRf of oroxylin A was 80. Linearity was in the range of 250-1500 ng/zone. LOQ was 120 ng/zone. Recovery was in the range of 94.5-101.2 %. Intermediate/interday/intra-day precision was below 2 % (n=5). Comparable results were obatined with a validated HPLC method.
J. Ethnopharmacol. 160, 140-148 (2015). HPTLC of hesperidin in the roots of Jasminum sambac on silica gel with ethylacetate - methanol - water - acetic acid 25:2:2:1. Quantitative determination by absorbance measurement at 254 nm. The hRF of hesperidin was 28.
J. Planar Chromatogr. 29, 256-263 (2016). HPTLC fingerprinting of flavonoids and phenolic acids in seven different Scutellaria species on silica gel with ethyl acetate – toluene – formic acid 50:49:1 for dichloromethane and methanolic extracts. Dichloromethane extracts were also developed on cyano phase with propan-2-ol – n-heptane – formic acid 50:49:1 and methanol – water – formic acid 60:39:1. The methanolic extracts were developed using methanol – water – formic acid 40:59:1. Detection with anisaldehyde reagent. Evaluation by chemometric processing. The best results for chemometric processing were obtained on the cyano phase.
Planta Medica 82(17), 1482-1486 (2016). TLC of the methanolic percolate of Elettaria cardamomum seeds on silica gel (with F254) with chloroform – ethyl acetate – methanol – formic acid 6:4:2:1, allowing the identification of kaempferol, rutin and quercetin by comparison to standards.
J. Planar Chromatogr. 30, 502-509 (2017). HPTLC of chlorogenic acid (1), gallic acid (2), caffeic acid (3), quercetin (4), p-coumaric acid (5) and kaempferol (6) in the fresh leaves, flowers, pods, and dried pods and seeds of M. oleifera on silica gel with toluene – ethyl acetate – formic acid 14:10:1. Quantitative determination by absorbance measurement at 282 nm. The hRF values for (1) to (6) were 1, 31, 41, 45, 49 and 52, respectively. Linearity was between 0.1 and 1.5 μg/zone for (1) to (6). LOD and LOQ were 142 and 382 ng/μL for (1), 126 and 343 ng/μL for (2), 114 and 410 ng/μL for (3), 116 and 301 ng/μL for (4), 125 and 356 ng/μL for (5) and 110 and 345 ng/μL for (6), respectively.
