Rose aroma chemical composition
Have you ever wondered what makes flowers smell so good? Among those flowers rose has been known for the unique, beautiful smell that attracts people. And this blog is about rose aroma's chemical compositions.
Citronellol /nickname “the mosquito plant”/. Citronellol is a monoterpenoid that is oct-6-ene substituted by a hydroxy group at position 1 and methyl groups at positions 3 and 7 /see picture 1/
Citronellol is found in plants like citronella plants (Cymbopogon nardus), lemon geraniums, lemongrass, eucalyptus, catnip, ginger, and of course, cannabis. The fresh, grassy smell of this terpene lends itself well as a fragrance ingredient to perfumes and is a base for botanical products like geranium oil and rose oil
How does citronellol form a scent?
Citronellol scents vary; they can have a fresh, floral smell or bright citrus smell, depending on the version. This is one reason why citronellol makes for such perfect perfume compositions. And citronellol comes in two forms that produce different scents. One form has a citrus smell and the other a sweet floral scent reminiscent of roses. /see picture 2/
Citronellol uses
Citronellol can be used for healing wounds, benefits for the skin, lowering heart rate, reducing some disease spreads.
Geraniol is a monoterpenoid consisting of two prenyl units linked head-to-tail and functionalized with a hydroxy group at its tail end. Geraniol is used in perfumery to ‘extend’ the scent of roses, bringing sheer, floral freshness to blends. /see picture 3/
Geraniol uses, effects
Geraniol has demonstrated anticancer activity in vitro and in vivo in a number of models of human cancer. And the pharmacological potential of geraniol in lung inflammatory diseases where oxidative stress was a critical control point.
Toxicity and effects
Toxicity of geraniol has been investigated in various organisms. Rat studies have shown that neither 10 000 ppm geraniol in the diet fed for 16 weeks nor 1000 ppm in the diet fed for 28 weeks produced any adverse effects.
b-Damascone is a major contributor to the aroma of roses, despite its very low concentration, and is an important fragrance chemical used in perfumery. Odor Description:A very powerful fruity floral note. DAMASCONE BETA is a complex odor of rose, plum, blackcurrant, wine and tobacco.
