 [The Essential Oil Composition of Dictamnus albus from Turkey, K. Hüsnü Can Başer, Müberra Koşar, Hulusi Malyer, Temel Özek, Planta Med. 60 (1994), 481-482]
-"The detailed study of volatiles of Dictamnus gymnostylis Steven. (Dictamnus albus L., original polymorphic species) considered by many to be the Burning Bush of the Bible, was conducted. In addition to methyl chavicol (~15%), (E)-anethole (~7%) and psoralen (~7%), the presence of over 60% of 1-allyl-4- (3-methyl-2-butenyloxy) benzene (dictagymnin) was confirmed. It was shown that this chemical rather easily decomposes into chavicol and very flammable hydrocarbon 2-methyl-1,3-butadiene = isoprene (b.p. 34°C). The secretion of isoprene, which can be especially intense on hot windless days, leads to formation of the isoprene cloud that may inflame without any harm to the source plant." \\

 The lemony and slightly herbal scent of this plant eminates not only from the flowers, but much more from the glandular cells spread over leaves and stems. Elevated temperature or slightest external force may liberate the volatiles as scent, which is especially based on (headspace of touched inflorescense) citronellal (0.1%), neral (1.8%), and geranial (7.2%), contributing citrus notes, embedded in a monoterpene matrix with myrcene (15.1%), limonene (27.0%), γ-terpinene (16.6%), and terpinolene (13.2%) and supported by minor amounts of (Z,Z)-4,7-decadienal (0.02%, algae-herbal), and (Z)-5-dodecenal (0.05%, orange-related). \\
