S (colchicine and gloriosine) at 254 nm (a) and 365 nm (b)SPharmacognosy Magazine, Volume 13, Problem 51, July-September 2017 (Supplement 3)ANKITA MISRA, et al.: Simultaneous Quantification of Bioactive Alkaloids in G. superbaFigure three: High-performance thin-layer chromatographic densitogram of standards (colchicine and gloriosine)spectrum of colchicine and gloriosine was obtained at 350 nm [Figure 2] right after scanning the complete UV variety, from 200 to 800 nm. Specificity on the developed strategy reflects the clear and comprehensive separation of marker(s) peak [Figure 3] and correspondingly in sample and normal. Rf value of colchicine and gloriosine was obtained at 0.72 0.02 and 0.61 0.01, respectively. The partnership involving concentration of marker compound and its corresponding peak area in sample band was investigated. The linear connection was also tested and identified appropriate for simultaneous quantification of both marker(s).High-performance thin-layer chromatographic method validationLinearity and quantificationThe linearity in the created system for simultaneous quantification of both markers was achieved at a concentration of 10000 ng/spot (each marker) using a statistically, acceptable regression coefficient (r2) of 0.9987 and 0.9983 for colchicine and gloriosine, respectively. Other statistical parameters of regression as summarized in Table 2 are within the limit of acceptance and hence confirming the linearity of created strategy. In the improvement of chromatogram [Figure 4], targeted marker(s) in sample was identified by comparing the retention element (Rf ), peak purity, and absorption spectrum with reference marker(s).Formula of 3-Bromo-6-fluoropicolinic acid Quantification information ( dry wt.Formula of 253443-56-0 of sample) reveal that the content material of colchicine and gloriosine varies from 0.PMID:24834360 035 .150 to 0.006 .032 , respectively. The maximum content material of colchicine too as gloriosine [Figure 5] was discovered in NBG-27, collected from Jorethang, West Sikkim. The residual plot for calibration curve of requirements, namely, colchicine and gloriosine (region vs. concentration) shows the constructive random pattern, indicating that a linear model provides a decent fit for the data. In addition to this, a good, statistically substantial correlation (Karl Pearson’s correlation coefficient: 0.68) was observed in the content of two metabolites within the species. This suggests the biosynthetic inter-conversion of colchicine and its derivatives.Figure four: Overlay ultraviolet absorption spectra in sample tract of NBG 23, NBG 24, NBG 25, NBG 26, NBG 27 (from front to back in order) and requirements, namely, colchicine (C) and gloriosine (G)Table 3: Peak purity test for the normal colchicine and gloriosine Requirements r (s, m)x R (s, m)yStandard Sample Standard Sample track track track track Colchicine 0.9875 0.9885 0.9980 0.9987 Gloriosine 0.9881 0.9997 0.9981 0.9789 s: Refers to begin; m: Refers to middle; x: Correlation of spectrum at the get started of peak with spectrum in the center in the peak; y: Correlation of spectrum at center of the peak with spectrum in the end of your peak Table 4: Precision research of regular compounds (colchicine and gloriosine) by high-performance thin-layer chromatography Marker Concentration (ng/spot) Interday Intraday Imply ( RSD) 0.075 0.067 0.033 0.084 0.044 0.015 SD 0.943 1.684 1.664 1.238 1.300 0.SpecificityThe specificity of strategy was estimated by evaluating the band of normal (colchicine and gloriosine) in sample answer by comparing the Rf and UV spectra.
