Chemistry:Damascone
Damascones are a series of closely related chemical compounds that are components of a variety of essential oils. The damascones belong to a family of chemicals known as rose ketones, which also includes damascenones and ionones. beta-Damascone is a contributor to the aroma of roses, despite its relatively low concentration, and is an important fragrance chemical used in perfumery.[1]
The odour strength of all the damascones are high. The aroma of α-damascone is described as "sweet, floral, metallic, fruity, apple, spicy, plum, minty, woody, green, berry",[2] β-damascone is described as "fruity, floral, black currant, plum, rose, honey, tobacco",[3] γ-damascone is described as "fruity, floral, rose, green, cooked apple, plum, thujonic, tobacco",[4] and δ-damascone is described as "fruity, sweet, rose, natural, petal, black currant bud, tobacco, woody, minty, brown, herbal".[5]
The damascones are derived from the degradation of carotenoids.[6][7]
