| Abstract: | The leaf oils of both subspecies of Atherosperma moschatum have been investigated to determine if there were any chemical differences between the two subspecies. While both subspecies of A. moschatum contained methyl eugenol (55–87%), safrole (5–20%) and linalool (1–6%), camphor (5–10%) was found to be only in the oils of A. moschatum subsp. moschatum and to be either absent or, at most, less than 0.5% in the oils of A. moschatum subsp. integrifolium. There was also a range of monoterpene hydrocarbons and 1,8-cineole, all in the range of 0.1–5%, that were present in subspecies moschatum but virtually absent in subspecies integrifolium. |
