Fig. 7. Results of the statistical treatment of data for the quantitation of xanthohumol, co-, n-, ad-humulone and co-, n-, ad-lupulone. This quantitation has been performed on the 63 crude hydro-ethanolic extracts of hop cone powder from Northern France, including 10 commercial varieties, 3 heirloom varieties and 50 wild hops (Fig. 1, Table 2). A. PCA biplot of quantitation data with score plot and loading plot of variables. Individuals were colored by collection site for a given observation. Variable contribution to component was represented by arrows length. B. Dendrogram of the hierarchical cluster analysis among the 63 hops based on the quantitation similarity (Ward's method, distance scale) (N = 3).
