- Essential oils were obtained by hydrodistillation of the leaves, flowers and fruits of Callistemon lanceolatus in 0.2-0.6%, 0.2% and 0.2% yield, respectively, and from the flowers and fruits of C. polandii in 0.1% and 0.1% yield, respectively. The oils were analyzed by a combination of column chromatography, GC and GC/MS. The leaf, flower and fruit oils of C. lanceolatus contained 1,8-cineole (41.1%) and alpha-pinene (11.6%); beta-pinene (51.2%) and 1,8-cineole (11.7%); and 1,8-cineole (38.8%) and alpha-terpineol (15.7%), respectively. The flower and fruit oils of C. polandii contained alpha-pinene (16.2%) and beta-pinene (45.8%); and 1,8-cineole (16.3%) and alpha-terpineol (13.5%), respectively.
