Chrysolina herbacea Modulates Terpenoid Biosynthesis of Mentha aquatica L.

Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant...

Study on essential oil of Mentha aquatica L. from Vietnam++++++

The characterization of essential oils of Mentha aquatica L grown in two Provinces of Vietnam was performed by means of gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) techniques. The major constituents of the essential oils were epi-bicyclosesquiphellandrene (58.9% and 52.4% respectively) and limonene (21.1% and 31.4% respectively) for Tha...
