A Very Lazy Guy's Way To The PR-171 Profits
Table 2 shows the regression equation for each reference compound, as well as the LOD and LOQ values and the mass spectrometry information. All the components showed good linearity (r > 0.9991) in a relatively wide concentration range. Tables ?Tables33 and ?and44 provide precision and recovery results of the 10 components, respectively. The intraday variations of the compounds were AZD9291 in vivo ions chromatograms for the determination of the PR-171 research buy 10 analytes. (a) Atractylenolide I (2.28?min). (b) Atractylenolide III (1.83?min). (c) Calycosin-7-O-��-D-glucoside (1.04?min). (d) Fangchinoline (0.98?min). ... Table 2 Calibration curves, LOD, and LOQ of the 10 major compounds. Table 3 Precision and repeatability for the assay of the 10 major compounds. Table 4 Recovery of the 10 major compounds in Fangji Huangqi Tang (n = 3). 3.3. Sample Analysis The developed UHPLC-MS/MS method was subsequently applied to analysis and quality evaluation of FHT. The content of these major constituents in FHT was shown in Table 5. Table 5 Content of the 10 major compounds in different batches of Fangji Huangqi Tang (��g/mL). 4. Conclusions A rapid UHPLC-MS/MS method was established for the comprehensive analysis of FHT. This method could separate the complex constituents in a short run time. Furthermore, YES1 MS/MS proposed high sensitivity which is helpful for the quantification of the low-content compounds. The method was successfully applied to the simultaneous determination of 10 bioactive compounds in FHT. This available, rapid, and reliable method is fit for routine analysis and effective quality control of this Chinese herbal prescription.
