Abstract

Representatives from eight wild populations of Hypericum perforatum L. were collected from Montana and Northern California at flowering, and subsequently analyzed for hypericin and pseudohypericin using HPLC analysis. Total individual plant concentrations in these wild populations were from 0.0003–0.1250% dry weight (DW) hypericin and 0.0019–0.8458% DW pseudohypericin. In general, hypericin concentrations were highest in the plant’s reproductive (flower and bud) tissues, followed by leaf and stem tissues, respectively. Hypericin and pseudohypericin concentrations were positively correlated in all samples, although the relative ratio of hypericin to pseudohypericin varied with site location.
