The essential oil obtained by hydrodistillation of the leaves and twigs of
Lemon-scented Myrtle, Darwinia citriodora (Endl.) Benth. cultivated in east
ern Australia was investigated by GC/MS, FTIR and NMR. Two chemical forms y
ielding from 0.5% to 1.1% oil, respectively, on a fresh weight basis were f
ound to be rich in either methyl myrtenate (56-76%) or an approximate 50/50
mix of methyl myrtenate and methyl geranate (49-75%). Other significant co
mponents in the oil were alpha -pinene (7.8%), (Z)-beta -ocimene (2.0%), li
nalool (1.7%) bicyclogermacrene (1.3%) and viridiflorol (2.3%).
