Syamasunder et. al. (2000) reported the constitution of essential oil from unripe and
ripe fruits of cinnamon. The GC-MS study indicated more than 90 components.
Variations exist in the composition of the two oils. The predominant components in the
oil of unripe fruits are -cadinene, -pinene and -pinene, while in the oil of ripe fruits
