Detection at UV 254 nm. The hRF values for (1-6) were 17, 23, 32, 38, 64 and 73, respectively. The bands were eluted using a TLC–MS interface and subjected to electrospray ionization-mass spectrometry (ESI-MS)._x000D_
J. Ethnopharmacol. 197, 184-194 (2017). HPTLC of arjunetin in Terminalia arjuna on silica gel with ethyl acetate – toluene – formic acid – acetic acid 12:6:1:2. Detection by spraying with anisaldehyde sulfuric acid reagent. The hRF value for arjunetin was 25.
J. Planar Chromatogr. 30, 126-130 (2017). TLC–direct bioautography of various hop varieties (Humulus lupulus L.) on silica gel with dichloromethane – acetonitrile 4:1 for ethanolic extracts and acetonitrile – methanol – dichloromethane 5:2:3 for aqueous extracts. The TLC plate was immersed in the bacterial suspension using the strains B. subtilis (ATCC 6633) and E. coli (ATCC 25922) and incubated under typical conditions.
J. Planar Chromatogr. 30, 313-322 (2017). HPTLC of cyclobenzaprine hydrochloride (1) and asenapine maleate (2) on silica gel with toluene ‒ methanol ‒ chloroform ‒ ammonia solution 33 % 50:30:60:1. Quantitative determination under UV light at 290 and 220 nm for (1) and (2), respectively. The hRF values for (1) and (2) were 45 and 75, respectively. Linearity was between 5 and 50 μg/zone for (1) and (2). The intermediate precision (n=2) was <2 %. The LOD and LOQ for (1) were 1.3 and 4.4 μg/zone for (1) and 1.2 and 3.9 μg/zone for (2), respectively. Average recovery rate was 99.2 % for (1) and 99.7 % for (2). There were no significant differences between the mean percentage recoveries and the precisions compared with a validated HPLC mehod.
(Peel). J. Planar Chromatogr. 30, 510-515 (2017). HPTLC of protocatechuic acid (1) and quercetin 4ʹ-O-β-D-glucopyranoside (2) in Allium cepa on silica gel with toluene – ethyl acetate – formic acid 3:6:1. Quantitative determination by absorbance measurement at 275 nm. The hRF values for (1) and (2) were 56 and 5, respectively. Linearity was between 100 and 700 ng/zone for (1) and (2). LOD and LOQ were 32 and 92 ng/zone for (1) and 30 and 92 ng/zone for (2). The intermediate precision was <2 % (n=6). Recovery ranged from 98.1 to 99.6 % for (1) and 98.2 to 99.9 % for (2).

J. Planar Chromatogr. 30, 527-530 (2017). HPTLC of the essential oil of Chamomile anthodium on silica gel with isocratic elution and gradient elution. Isocratic elution with 0 %, 20 %, 40 %, 60 %, 80 %, and 100 % (v/v) heptane in toluene; 0 %, 2.5 %, 5 %, 10 %, 15 %, and 20 % ethyl acetate in toluene; and_x000D_ 2.5 %, 5 %, 10 %, 15 %, 20 %, and 30 % ethyl acetate in heptane. Gradient elution with single void volume of the mobile phase of pure heptane, followed by a 10 % solution of ethyl acetate in toluene. Detection by spraying with anisaldehyde reagent, followed by heating at 100–105 °C for 5–10 min. Qualitative determination under UV light at 366 nm. The obtained separation is better with gradient elution in comparison to isocratic elution.
