No-targeted MS/MS data was processed by qualitative MassHunter and Mass Profiler. A total number of 8261 metabolites at 5000 cps threshold were extracted to avoid false positives. Data was further processed to get molecular features which http://www.selleckchem.com/products/Fludarabine(Fludara).html are significant and differentially expressed in the samples using one way ANOVA with Benjamini-Hochberg correction and fold change analysis. A 40 fold decrease in molecular features was observed after selecting the metabolite with fold change ≥2 and of high abundance.

PCA was performed via transformation of measured variables into uncorrelated principal components, each being a linear combination of the original variables. Analysis of molecular features gave a clear separation in PCA space of the analyzed S. asoca samples

and drugs [ Fig. 2]. Fig. 2A shows more variability among MFs from different plant parts [i.e. bark, regenerated bark, flower and leaves], as compared to that of variability between MFs obtained from hot and cold water extracts of the same part of the plant. The first PCA axis in the analysis of plant parts showed approximately 26.8% of the total variance allowing a full separation of the samples [ Fig. 2A]. It indicates large biological fluctuation in metabolite composition of plant parts. The leading PCA axes for metabolite profiles of the Ashokarista showed 40.87% of the total metabolic variance. These observations reflect that metabolites Androgen Receptor Antagonist research buy in different plant parts are very diverse and extraction procedure [hot and cold water extract] has less effect on variation in molecular features. Interestingly as show in Fig. 2B, major variations were observed only in the Ashokarista formulations as compared to plant parts. Variations in PCA space was due to the marker ions that accounted for the difference among the S. asoca samples and drugs. Additionally, Venn diagram indicated 53.59% variations in between

the formulations of Ashokarishta. SNK Post Hoc test was applied to find out the differentially and non-differentially expressed molecular features. A total number of 637 metabolites were selected on the basis of their frequency across the Adenylyl cyclase samples and significance [p < 0.05]. Table 2 showing the entities found to be differentially expressed and entities found not to be differentially expressed across the samples. PLS-DA, a widely used supervised pattern recognition method capable of sample class prediction was used to construct and validate a statistical model for sample classification and discrimination. The results of sample classification are presented in terms of discrimination and recognition abilities, representing the percentage of the samples correctly classified during model training and cross-validation. The recognition ability of the model was found to be 93.33% which was almost equal to the discrimination ability [94.
