Phytochem. Anal. 28, 87-92 (2017). HPTLC fingerprint of the aerial parts of Justicia secunda on silica gel with chloroform – methanol – water 6:4:1. Detection by dipping into 200 mL enzyme solution (2000 U of alpha-D-glucosidase dissolved in 200 mL buffer solution prepared with 10 g sodium acetate in 250 mL double-distilled water, pH 7.5 with acetic acid), followed by incubation for 1 h in a humid desiccator and dipping into 200 mL of substrate solution (2 mg/mL 2-naphthyl-alpha-D-glucopyranoside in 50 % aqueous ethanol and 2.5 mg/mL Fast blue salt B in double-distilled water, mixed 1:1 before applying). Detection under UV 366 nm.
of caffeic acid, ferulic acid, ?-sitosterol, and lupeol in Convolvulus pluricaulis Choisy and its adulterants/substitutes
J. Planar Chromatogr. 31, 429-436 (2018). HPTLC of _x000D_caffeic acid (1), ferulic acid (2), β-sitosterol (3), and lupeol (4) on silica gel with toluene – ethyl acetate – formic acid 85:15:1. Quantitative determination by absorbance measurement at 366 nm for (1) and (2) and 580 nm for (3) and (4). The hRF values for (1) to (4) were 14, 29, 48 and 63, respectively. Linearity ranged between 100-600 ng/zone for (1) and (2) and 200-700 ng/zone for (3) and (4). LOD and LOQ were 49 and 149 ng/zone for (1), 93 and 282 ng/zone for (2), 194 and 589 ng/zone for (3) and 36 and 109 ng/zone for (4), respectively. The intermediate precision was <2 % (n=6). Average recovery was 99.6 % for (1), 99.9 % for (2), 99.2 % for (3) and 99.5 % for (4).
