Use of chemical markers for identification of species in the Genus echinacea
Highly-priced seed and root of two commercially important species of echinacea, Echinacea angustifolia and Echinacea pallida, are very difficult to distinguish macro- and micro-scopically. In support of high standards of quality and in effort to clear the confusion on the medicinal plant market, we have developed a chemical fingerprint test for authentication of echinacea seed using chromatographic techniques (TLC and HPLC). This test is able to reveal whether seed is of true species, or a cross between the species. Reference will also be made to authentication of Echinacea species by chemical fingerprinting of lipophylic root extract.
