J. Liq. Chromatogr. Relat. Technol. 43, 233-246 (2020). HPTLC of lutein (1) and lactucaxanthin (2) in three varieties of lettuce (Iceberg, Romania, and green lettuce) on silica gel with heptane - acetone 7:3. The hRF values for (1) and (2) were 44 and 41, respectively.
J. Liq. Chromatogr. Relat. Technol. 43, 351-360 (2020). HPTLC of colchicine (1) and gloriosine (2) in Gloriosa superba on silica gel with chloroform - acetone - di-ethylamine 5:4:1. Quantitative determination by absorbance measurement at 350 nm. The hRF values for (1) and (2) were 50 and 40, respectively. The study promotes the use of G. superba as an adjuvant therapy in gouty arthritis and helps explore the elite chemotype(s) with validated pharmacological action to meet out the medicinal and commercial demands.
J. Liq. Chromatogr. Relat. Technol. 43, 414-423 (2020). HPTLC fingerprint of Ganoderma lucidum fruiting body on silica gel with toluene - tetrahydrofuran - acetic acid 70:30:1. Detection by dipping into a solution of 10% sulfuric acid in methanol, followed by heating at 100 ºC for 3 min. Qualitative determination under UV light at 254 and 366 nm. The hRF values for ganoderic acids D, B, A, G and C2 were in the zone between 10 and 50. This zone was used for quantification of total triterpene acids by absorbance measurement at 260 nm. Linearity of each of the main peaks between hRF 10 to 50 was determined. The linear range of ganoderic acid A was between 200 and 500 ng/zone. The study proposes a new method for evaluation, based on “comprehensive high-performance thin layer chromatography (HPTLC) fingerprinting.” Instead of several different methods using different chromatographic techniques, a single HPTLC analysis for identification of Ganoderma lucidum fruiting body with a test for adulteration and quantitative determination of the content of total triterpene acids is proposed. As an alternative to the current tests in the USP monograph on G. lucidum fruiting body this HPTLC method is a single, low-cost test, which eliminates the UHPLC assay of total triterpene acids.
J. Liq. Chromatogr. Relat. Technol. 43, 388-393 (2020). HPTLC of carpaine in the leaves of Carica papaya on silica gel with chloroform - methanol 7:3. Detection by dipping into Dragendorff’s reagent. Quantitative determination by absorbance measurement at 510 nm. The hRF value for carpaine was 59. Linearity was between 0.4 and 1.2 µg/zone. Intermediate precisions were below 2 % (n=3). The LOD and LOQ were 11 and 33 ng, respectively. Recovery was 101.6 %.
J. Liq. Chromatogr. Relat. Technol. 43, 300-304 (2020). HPTLC of thymol, carvacrol and linalool in Solidago canadensis on silica gel with n-hexane - acetone 4:1. The method was compared with bilateral band compression (BBC) of the 10 mm wide lanes of HPTLC separation, resulting in more than 6 times increase in peak height and peak area. In BBC a solvent flow perpendicular to the direction of chromatogram development squeezes the chromatographic bands into a smaller area The method improved detection sensitivity of sample components with low abundance.
J. Liq. Chromatogr. Relat. Technol. 43, 445-454 (2020). HPTLC of aniline (1), 2,4-xylidine (2) and 4-aminoazobenzene (3) in chili oils, pickles and related food matrices on silica gel with chloroform - acetic acid 9:1. Quantitative determination by absorbance measurement at 280 nm. The hRF values for (1) to (3) were 53, 43 and 82, respectively. Linearity was in the range of 2-14 ppm for (1) to (3). The LOD and LOQ were 0.0015 and 0.0045 ppm for (1), 400 and 1200 ppm for (2) and 200 and 600 ppm for (3), respectively. Mean recovery rate was 100.2 % for (1) and 100.9 % for (2). The azo aryl amines were also analyzed using a TLC-MS interface.
J. Liq. Chromatogr. Relat. Technol. 43, 328-335 (2020). HPTLC of verapamil, diltiazem, ivabradine, and its related analogs on silica gel with acetonitrile - methanol (acidified with 25 % formic acid) with the following volume fraction of methanol: 0.25, 0.20, 0.15, 0.13 and 0.10. Detection under UV 254 nm. Retention behavior was investigated and quantitative structure retention relationship (QSRR) modeling was performed with the use of the stepwise multiple linear regression.
J. Planar Chromatogr. 33, 203-206 (2020). HPTLC of profenofos in visceral samples on silica gel with hexane - acetone 7:3. Detection by spraying with cupric acetate reagent (4 g of cupric acetate in 100 mL distilled water), followed by heating at 120 ºC for 10 min. The hRF value for profenofos was 44.
