Essential Oils from the Leaves of Three New Zealand Species of Pseudopanax (Araliaceae)

  • Roderick J. Weston EMAIL logo

Essential oils from three of the eleven endemic New Zealand species of Pseudopanax, P. arboreus, P. discolor and P. lessonii, were found to have a fairly uniform composition which was different from that of the oils of Raukaua species that were formerly classified in the Pseudopanax genus. Oils of the three Pseudopanax species all contained significant proportions of viridiflorol and a closely related unidentified hydroazulene alcohol in common. In addition, the oil of P. arboreus contained bicyclogermacrene, linalool and long chain hydrocarbons. The oil of P. discolor contained nerolidol in abundance (36.3%) together with linalool and epi-α-muurolol. The oil of P. lessonii contained a complex mixture of sesquiterpene alcohols including epi-α-muurolol and a mixture of long chain hydrocarbons. Nerolidol and linalool provided the oil of P. discolor with a pleasant floral aroma, but the yield of oil was very low (0.01%).
