초록
The effects of gamma ray or electron beam irradiation on herbaceous medicinal plantswere investigated in terms of the composition of volatile constituents using the aerial parts orleaves of Artemisia princeps Pamp. cv. Ganghwayakssuk and Artemisia argyi cvs. Namhaeyakssukand Hwanghaessuk. The composition of volatile constituents in leaves was clearly distinguishableamong the three Artemisia cultivars. However, the relative proportions of the major volatile constituentssuch as 1,8-cineole, α-pinene, camphene, santolina triene, and artemesia triene, weresimilarly changed in two or three cultivars by gamma ray or electron beam irradiation. In particular,the proportion of 1,8-cineole was increased up to 1.29- to 1.71-fold in the three cultivars afterirradiation with gamma ray. These results suggest that gamma ray or electron beam irradiationcan be applied to modulate the composition of volatile constituents in the leaves of Artemisiaplants.
