"Acorus calamus L. yields different races depending upon the number of chromosomes in the plant cells and consequently different drug types with varying content of β-asarone [= (Z)-asarone]. The phenylpropane derivative proved to be carcinogenic in several animal tests. The diploid drug does not contain traceable amounts of beta-asarone, the triploid variety contains 0.3 per cent in the rhicome, the tetraploid yielded two races with a) 2% and b) between 4% and 8% β-asarone. For reasons of optimal drug safety the use of asarone-rich races should be avoided. They can be distinguished by a fast and safe method of determining the extinction of the drug extract at the β-asarone maxima of 253 and 303 nm." \\ | "Acorus calamus L. yields different races depending upon the number of chromosomes in the plant cells and consequently different drug types with varying content of β-asarone [= (Z)-asarone].

"The pale yellow to pale brown volatile calamus oil has an odor described as //'woody-spicy with increasingly sweet afternotes and great tenacity'// that resembles //'dried milk or sweet leather, slightly creamy-nutty'//, and has been compared to the fragrance of a milk-truck or shoe-repair shop (Arctander 1960). This characteristic aroma is derived from the chemical compound (Z,Z)-4,7-decadienal which is present in the oil at about 100 000 times its odor threshold value (van Lier, van der Linde, and van der Weerdt 1986)." \\ | "The pale yellow to pale brown volatile calamus oil has an odor described as //'woody-spicy with increasingly sweet afternotes and great tenacity'// that resembles //'dried milk or sweet leather, slightly creamy-nutty'//, and has been compared to the fragrance of a milk-truck or shoe-repair shop (Arctander 1960).
