CBS 119 (2017) 14-15. HPTLC of Cannabis sativa and standards cannabidiol (CBD), tetrahydrocannabinol (THC), and cannabinol (CBN) on silica gel with n-heptane – diethyl ether – formic acid 75:25:0.3 with chamber saturation for 20 min to a migration distance of 70 mm. Detection by spraying with Fast Blue salt B reagent (250 mg o-dianisidine bis(diazotized) zinc double salt in 10 mL water, 25 mL methanol and 15 mL dichloromethane), evaluation under white light. Quantitative determination by absorbance measurement at 210 nm prior to derivatization (for cannabinoid acids 285 nm). For the screening of THC-free samples the limit test can be used. The EU limit of 0.2 % is easily detected with or without detection. The %RSD of the assay prior to derivatization is 1.5 % and after derivatization 2.1 %. The LOD is 10 ng/zone.
in experimental animals. J. Ethnopharmacol. 224, 15-26 (2018). HPTLC of quercetin in the flowers of C. trenatea on silica gel with chloroform – methanol – formic acid 15:3:2. Quantitative determination by absorbance measurement at 254 nm. The hRf value of quercetin was 52.
J. Planar Chromatogr. 31, 163-168 (2018). HPTLC bioautography of the essential oil in the bark of Ocotea quixos on silica gel with toluene – ethyl acetate – petroleum ether 97:7:20. After separation, the Mueller‒Hinton culture medium was deposited on the Petri dish which contained the chromatographic plate. The medium contained the selected microorganisms: 500 μL Bacillus subtilis ATCC 6633 ATCC and 500 μL P. aeruginosa ATCC 9027. The plate was incubated at 37 °C for 48 h. The molecule with activity proved to be cinnamyl acetate at an hRF value of 53.
germplasms from Western Himalayas. Pharmacogn. Mag. 14, 141-146 (2018). HPTLC of precocene I (1) and precocene II (2) in the germoplasms of Ageratum conyzoides on silica gel with toluene – ethyl acetate 49:1. Quantitative determination by absorbance measurement at 300 nm. The hRF values (1) and (2) were 60 and 23, respectively. Linearity was between 100 and 500 ng/zone for both (1) and (2). LOD and LOQ were 5 and 16 μg/mL for both (1) and (2). The intermediate precision was <5 % (n=3). Average recovery was 99.7 % for (1) and 102.9 % for (2).
Solanum species used as ‘Brihati’ and its market samples using a validated high-performance thin-layer chromatography method
J. Planar Chromatogr. 31, 421-428 (2018). HPTLC of solamargine in Solanum species on silica gel with dichloromethane ‒ methanol ‒ 2.5% aqueous ammonia 75:25:2. Detection by dipping into anisaldehyde sulfuric acid reagent, followed by heating at 110 °C. Quantitative determination by absorbance measurement at 540 nm. The hRF value for solamargine was 15. Linearity was between 25 and 300 ng/zone. LOD and LOQ were 1 and 4 ng/zone. The intermediate precision was <2 % (n=3). Average recovery was 101.2 %.
(Dryopteridaceae, pteridophyte). Helv. Chim. Acta 68, 1251-1274 (1985). TLC of various complex phloroglucinols on silica impregnated with citric acid - phosphate buffer using methanol - isopropyl ether - cyclohexane 10:35:55, chloroform - hexane - ethanol 45:45:10, chloroform - hexane - ethanol - acetic acid 45:35:16:4 or ethyl acetate - cyclohexane - acetic acid 60:35:5. Detection by UV 254 and 366 nm and by spraying with a 0.1 % sol. of "fast blue salt B". Checking of doubtful spots was achieved by scraping, elution with ethyl acetate/ether and rechromatography in another system.
