- ... Cultivars of hop, Humulus lupulus L., are of economic importance for breweries, since hop cones contain a resinous fraction, responsible for the bitter taste of beer, and a volatile fraction, which contributes to its flavour. Till now research on the presence of volatile compounds in the leaves of hop plants has not been reported. Dried leaves of ten cultivars were submitted to hydrodistillation, ...

- ... cis-Jasmone, or (Z)-jasmone, is well known as a component of plant volatiles, and its release can be induced by damage, for example during insect herbivory. Using the olfactory system of the lettuce aphid to investigate volatiles from plants avoided by this insect, (Z)-jasmone was found to be electrophysiologically active and also to be repellent in laboratory choice tests. In field studies, repel ...
