2.1.5. Bicyclic monoterpenes
Sabinene, the major volatile in this category was found primarily
in Kaffir lime blossoms as its second most abundant volatile
(18% of total headspace composition). This further contributed to
Kaffir lime’s distinct volatile composition compared to all other
blossoms (2% sabinene). Alpha and b-pinene are chemically
unstable bicyclic terpenes due to a strained four membered ring.
As such they are found at low levels and evenly distributed in all
the blossom types in this study.
