batavia and Korintji cassia (Lawrence, 1967). Eugenol is absent in the oil. The leaf
on distillation gives about 0.4–0.5% oil, having about 45–62% cinnamaldehyde and
about 10% phenols. The properties of Indonesian cassia bark and leaf oils are regarded
similarly to those of Chinese cassia bark and leaf oils (Table 7.4). However, later reports
indicate a chemical composition that is distinctly different. Xiao-duo et al. (1991)
reported 1,8-cineol as the major component in bark and leaf oils (Table 7.5).
Yu-Jing et al. (1987) investigated the chemical composition of a physiological type
rich in borneol (Mei Pan tree) and detected 34 constituents in leaf oil (Table 7.6).
