| The steam distilled oil from Acorus calamus (yield 1.5-4.8%) owns a "...peculiar but pleasant, slightly sweetish, fatty odour reminescent of stale milk." A fraction of the oil (124-150°C/5 torr) contained sevral saturated and unsaturated aliphatic aldehydes C6-C10 and aromatic aldehydes like cuminic aldehyde, anisic aldehyde, and cyclocitral. Of the decadienals found, (Z,Z)-4,7-decadienal (500ppm, odour threshold 4.2ppb) showed an odour most reminescent of calamus oil. | The steam distilled oil from Acorus calamus (yield 1.5-4.8%) owns a "...peculiar but pleasant, slightly sweetish, fatty odour reminescent of stale milk."
