✦ Synopsis
The essential oil obtained from fresh leaves of Archirhodomytau beckleri (F. Muell.) A.J. Scott indicated that the species existed in two chemical forms. One form was rich in (E)-p-ocimene (69-87%), with the remaining oil being composed of a mixture of mono-and sesqui-terpenes in small amounts. The oil yield of this chemotype was 0.2-0.5%. The second chemical form, obtained in 0.0242% yield, contained a mixture of a large number of mono-and sesqui-terpenes, the main members of which were a-pinene, 8-caryophyllene, a-terpineol, (E)nerolidol and a-, p-, and y-eudesmol. This second chemotype occurred in both of the disjunct areas in which A . beckleri occurred while the (E)-p-ocimene chemotype occurred only in the disjunct southern range of the species.
