Has anyone identified the compound(s) that make up the distinctive and intense scent of Himalayan Balsam (Impatiens glandulifera)?
I’ve found a number of compounds associated with Impatiens sp., but it does not look like any of them would be carriers of the scent:
- 2-Methoxy-1,4-naphthoquinone or "lawsone methyl ether" [an anti-inflammatory, fungicidal agent]
- 2-Hydroxy-1,4-naphthoquinone (Lawsone) [a dye that is also the principal component of Henna]
- Methylene-3,3'-bilawsone (Diphthiocol; 3-[bis(2-hydroxy-1,4-naphthoquinonyl)]methane)
- α-Parinaric acid [a polyunsaturated fatty acid]
Neither the naphthoquinones nor the fatty acid are described as having any particular scent, and they are apparently all non-volatile solids, which would rule them out.
I was unable to find any more information online, but maybe someone who is more involved with this kind of research has some pointers. Thank you!
