Atractylon Is a Major Sesquiterpene in Young Atractylodes lancea Plants Raised from Shoot Cultures

概要

論文の詳細を見る
In the rhizomes of young Atractylodes lancea plants micropropagated from shoot tips, the major sesquiterpene of the essential oils was atractylon, which is the major sesquiterpene of A. japonica or A. ovata, though in the rhizomes of older plants, hinesol and β-eudesmol was the major sesquiterpenes. Thus, the accumulation pattern of essential oils varies depending on the plant age. The presence of atractylon in A. lancea does not necessarily mean that the plant is a hybrid between A. lancea and A. japonica or A. ovata, both of which contain atractylon as the major sesquiterpene in the rhizome. A. lancea plants have an ability to biosynthesize atractylon genetically. The rhizomes of young micropropagated A. ovata plants accumulated atractylon as a major essential oil component, but its content was lower than that of the mother plant.
