Oct-7-enal (CAS 21573-31-9) is a naturally-occurring unsaturated aldehyde, isolated from the volatile oil of the thistle Cirsium dipsacolepis(Asteraceae). Known as yamagobo, this is a perennial herb that grows in Japan on dry plains, which is the source of bioactive compounds and which edible roots, once pickled, are used to accompany meat-based foods due to their extraordinary flavor.
