Journal Article

Publication Abstract

The leaf and stem of Callistemon polandii, on hydrodistillation, gave 0.008% and 0.004% of oils respectively on a fresh weight basis. GC and GC-MS analysis of the oils resulted in the identification of 60 and 44 constituents, representing 98.2% and 99.9% of the oils from the leaf and stem respectively.  The major constituents in the leaf oil of C. polandii were palmitic acid (25.2%), tetradecanoic acid (10.8%) and caryophyllene oxide (9.6%). While the major constituents of the stem oil were palmitic acid (31.7%), caryophyllene oxide (6.4%), tetradecanoic acid (5.9%), and 9-hexadecanoic acid (5.6%).
