 Fragrant herb, 30-120cm high, native to the southern part of India (Karnataka, Tamil Nadu, Andhra Pradesh, Maharashtra); leaves alternate, pinnatisect, bluish green; flowers numerous, yellow.
-"Davana oil is used in making perfumes of sweet and fruity fragrances. When applied on the skin, Davana is said to smell differently on different persons. This peculiar property is highly valued in high class perfumery to create fragrances with truly individual notes. Davana leaves and stalks are used in making bouquets, garlands, fresh or dry flower arrangements." [[http://en.wikipedia.org/wiki/Artemisia_pallens]]

 Davana oil, the essential oil of A.pallens, contain more than 50 compounds. Main components are  furanoid sesquiterpenes like (Z)-davanone (38%), (E)-davanone (5%), (E)-hydroxydavanone (2%) and (Z)-hydroxydavanone (3%), iso- and nor-davanone, davana ether, davana furan and davanol, together with nerolidol (10%) and cinnamyl cinnamate (2%). \\

-"A number of important observations can be made from the olfactometry evaluation of the crude natural davana oil: (1) major components do not necessarily correlate with major sensory responses; (2) powerful sensory responses are observed for minor/trace constituents; (3) davanone with a value of 40 is not the major sensory component, yet it affords the greatest MS response; (4) eight other components had intensities greater than that of davanone; and (5) a number of powerful sensory components are essentially below TIC detection limits and, hence, remain unidentified at this time. In addition, all of the sensory attributes identified in the GC/O

 analyses were positive in nature and could be described as fruity, spicy, musty, green, sweet, and pleasant. These olfactometry results are in agreement with the literature in that davanone has been reported to have little to no aroma. On the other hand, minor components are thought to contribute significantly to the aroma of davana oil." \\

+„Davanone, a sesquiterpene ketone, is the major component and quality driving factor of davana oil. High-quality material usually boasts a davanone content at or above 50%. Grades around 45% will usually be offered at a discount. Nerol is present at 10%, while geraniol is found at 5%. Surprisingly, its largest component, cis-davanone, has been shown to be odorless. Davana’s signature aroma actually comes from davana ether, davana-furans, dihydrofurans, dihydrorosefurans, trans-hydroxy davanone, hydroxy dihydroxorosefuran and furano-nor-diterpenoid blended with cinnnamyl cinnamates-even though they are all found at less than 2% in the oil... Davana essential oil boasts a potent, exquisite scent. Its character is shockingly reminiscent of old spirits like cognac, with sharp, dry fruit notes, and a full body with thick honey herbaceous notes.“ \\
