Quantitative determination by absorbance measurement at 242 nm. The hRF values for (1) to (5) were 17, 38, 51, 65 and 66, respectively. Linearity was in the range of 15-650 ng/zone. LOD and LOQ were in the range of 5-50 and 15-150 ng/zone, respectively. The intermediate precision was below 5 % (n=3). Recovery ranged from 95 to 104 %.
chromatography of tropane alkaloids from Datura innoxia Mill extract in pseudo-reversed-phase systems
J. Planar Chromatogr. 29, 38-44 (2016). HPTLC of tropane alkaloids (atropine sulfate, homoatropine, L-hyoscyamine, scopolamine hydrobromide, tropine and scopolamine oxide) in Datura innoxia Mill. on silica gel with methanol – buffer pH=9 1:1. The electric field gradient for the electrochromatography was 1.2 kV/cm. Detection by spraying with Dragendorff reagent. The electrostatic field was referred to be an important factor in broadening the applicability of conventional TLC systems.
Rev. Bras. Farmacogn. 26, 197-202 (2016). HPTLC of tannins (1), flavonoids (2), anthraquinones (3), terpenes (4), cardiotonic glycosides (5) and alkaloids (6) in Myracrodruon urundeuva on silica gel with toluene – acetic acid – formic acid 70:167:14 for (1), ethyl acetate – methanol – water 8:1:1 for (2), toluene – acetone – chloroform 8:5:7 for (3), hexane – ethyl acetate 1:1 for (4), ethyl acetate – methanol – water 20:3:2 for (5), and ethyl acetate – formic acid – acetic acid – water – ethyl methylketone 86:16:23:47:78 for (6). Detection by spraying with 1 % potassium ferricyanide – 2 % iron(III)chloride 1:1 for (1), 2 % aluminium chloride for (2), 5 % potassium hydroxide for (3), anisaldehyde-sulfuric acid reagent for (4), Kedde reagent for (5) and Dragendorff reagent for (6).
