Abstract (en)

[origin: US4351346A] Aromatic substances to be applied to tobacco to improve aroma characteristics are prepared by exposing an alcoholic extract, which contains carotenoids and may additionally contain diterpenes and has been isolated from fresh tobacco plants, to ultraviolet light and oxygen. Additionally, aromatic substances may be produced from xanthophyll containing plant extracts by the same method.
