Isobaeckeol (6‐hydroxy‐2,4‐dimethoxy‐3‐methylisobutyrophenone) accounted for over 80% of the leaf essential oil of one chemotype of Austromyrtus dulcis (C. T. White) L. S. Smith, the oil of which was obtained in 0.9‐1.2% yield based on fresh weight of leaves. A second chemotype of A. dulcis contained an entirely terpenoid essential oil with β‐pinene (34‐45%) and 1,8‐cineole (24‐35%) being the major components. The essential oil of this second chemotype was obtained in 0.3‐0.6% yield. The essential oil of A. tenuifolia (Sm.) Burret., obtained in 1.8‐3.0% yield contains isobaeckeol (97‐98%) as its principal component with the remainder of the oil being composed of terpenes, mainly sesquiterpenes. The oil of A. tenuifolia was qualitatively similar to one chemotype of A. dulcis .
