Chemometric analysis HPTLC flavonoids fingerprint for methanolic combinatorial extracts along with their respective standard a. HPTLC chromatogram (UV 366 nm) tracks: Flavonoids S1 (Std): Quercetin ; and W. somnifera (W); A. racemosus WA1 (4:1); O. basilicum WO3 (1:4); P. emblica WP3 (1:4); B. monnieri WB2 (1:1); T. sinensis WT3 (1:4) methanolic combinatorial extracts. b. 2D line profile of STD (samples are interpreted in same manner displayed in Supplementary data Fig S4) filter channels red (R), green (G) and blue (B). c. Superimposed line profile plot for comparing the methanolic combinatorial extracts with Rf distance (Black- W; Red- WP3; Blue-WO3; Green-WB2; Orange-WA1; Yellow-WT3). d. PCA Score plot of PC1 & PC2 mined from data analysis of the extracts rendering to the intensities of the pixels and PCA Loading plot for the projection of samples chromatogram for their secondary metabolites data variance.
