The leaf essential oil of two chemotypes of Backhousia anisata vickery

Backhousia anisata Vickery has been found to occur in two chemotypes. One chemotype contains E ‐anethole (90+ %) as its major component with small amount of methyl chavicol (< 5%) and very little Z ‐anethole( < 0.1 %). The second chemotype contains methyl chavicol (60‐75%) as its major compound with smaller amounts of E ‐anethole (< 25%) and Z ‐anethole (<0.1%). In both cases the oil yield was 1‐1.5% based on fresh leaves.
