Induction of sesquiterpenoid production by methyl jasmonate in aquilaria sinensis cell suspension culture / Michiho Ito in The journal of essential oil research, Vol. 17 N° 2 (Mars-Avril 2005)

Cells were harvested after seven days of incubation and subjected to solid phase micro-extraction to produce an extract that was analyzed by GC/MS. Three peaks appeared on GC and were identifi ed as α-guaiene, γ-guaiene (= 1(10),11-guaiadiene), and α-humulene based on their mass fragmentation patterns and 13C-NMR data. The production of the guaiene derivatives and α-humulene showed different kinetics, which may mean they are the products of different induced biosynthetic enzymes.
