Mentha arvensis; biosynthesis; calyx; chemotypes; chromosome number; cineole; diploidy; essential oils; leaves; linalool; menthone; races; Europe; North America
Abstract:
... Most North American populations of Mentha arvensis differ from those in Europe in leaf and calyx characters, but the extremes of variation overlap. However the former have a diploid chromosome number of 96 and the latter 72. The North American populations are morphologically very variable and much of this variation is genotypic. However, none of it is discrete and, as it shows little geographic or ...
... The essential oil from Artemisia californica yeilds five terpenoids in major amounts: 1,8—cineole, artemisia ketone, α—thujone, isothujone, and camphor. Of these, camphor is most toxic, followed by 1,8—cineloe. Artemisia ketone is least toxic. Terpenoids found in minor amounts include β—pinene, borneol, and the sesquiterpene hydrocarbon caryophyllene. These are intermediate in toxicity. Amount and ...
