Phytochemical variation in North American populations of wild tarragon (Artemisia dracunculus L.).

Artemisia dracunculus L. has a long history of human use as a culinary herb and medicine, and throughout its range human populations have utilized the plant for the treatment of a wide variety of diseases. The species has a distribution that spans Western North America, parts of Europe, as well as Eastern and Central Asia. Previous experiments have shown that flavonoids contained in an ethanolic extract of wild tarragon have significant results in treating processes associated with diabetic related illnesses. Phytochemical analyses of extracts made from wild growing populations throughout the western U.S., as well as from propagules of those same individuals grown in a common garden, were conducted using Liquid Chromatography/Mass Spectrometry (LC/MS). Qualitative results of both sets of extracts showed that the source of plant material is extremely important because not all of the active compounds are present in the U.S. populations. Quantitative analysis also showed great variation in the amount of the bioactive flavonoids that were found to be present in the extracts. Karyological studies have shown that only diploid populations have been found in the U.S., while abundant polyploidy exists in European and Asian populations. Previous studies have shown that different cytotypes of A. dracunculus exhibited variation in phytochemical content and this may be a factor in the lack of certain flavonoids in plants from North America.
