OCIMENE Usage And Synthesis
Descriptionβ-Ocimene is a monoterpene that has been found in a variety of plants and is a volatile compound involved in plant-plant signaling and plant defense against pests. It is emitted by tea (C. sinensis) plants in response to a jasmonic acid combined with mechanical damage (JAMD) model of herbivore attack. β-Ocimene reduces the number of winged aphids (M. persicae) that settle on Chinese cabbage and the feeding time and number of nymphs produced by aphids on leaves. The aphid endoparasitoid A. gifuensis demonstrates a preference for β-ocimene-treated Chinese cabbage over control plants in a wind tube two-choice test. β-Ocimene (100-1,000 ppm) also has antioxidant activity in a thiobarbituric acid reactive substances (TBARS) assay.
Chemical Properties3,7-Dimethyl-1,3,6-octatrine has a warm herbaceous odor.
OccurrenceReported found in black currants, currant leaves, mentha pulegium oil, origanum oil, passion fruit, citrus peel oils, guava, strawberry jam, cinnamon bark, Thymus vulgaris, hop oil, tea, soybean, parsnips, tarragon, origanum, Ocimum basilicum, curcuma, ouzo and pimento berry
