The Effect of Mechanical Wounding on the Composition of Essential Oil from Ocimum Minimum L. Leaves
2001
Dimitrios Zabaras | S. Grant Wyllie
The effect of mechanical damage on the composition of the essential oil obtained from eugenol-rich Ocimum minimum leaves was determined over 48 hours. Changes in the levels of five oil-constituents were detected in the first post-wounding day but only one of those components (camphor) exhibited the same behaviour the day after. The levels of eugenol (-4.8%) and linalool (+2.5%) were affected the most by the wounding process. Principal component analysis (PCA) showed the post-wounding response to be independent from the pre-wounding levels of the particular compounds expressing the response and from the overall leaf oil-composition.
