[Aromatic constituents in fresh leaves of Lingtou Dancong tea under Basilepta melanopus Lefevre stress].
The study showed that under different degrees of Basilepta melanopus Lefevre stress, the kinds of aromatic constituents in the fresh leaves of Lingtou Dancong tea plant increased evidently, being the most (36 kinds) under medium stress. With the increase of the stress, the contents of 9 aromatic constituents like 1,6-methylene annulene increased, whereas those of 8 constituents as linalool decreased. Light stress induced the appearance of 4 aromatic constituents like 2-methyl hexadecane, while medium stress induced that of 6 constituents as H1-docosanol. Different degrees of B. melanopus stress could induce the synthesis of 23 aromatic constituents like 1,6-methylene annulene, but inhibit the formation of 6 constituents as nonanal.
