The best known members are the resin acids obtained from the non-volatile portion of many oleoresins, especially those obtained fram conifers. Diteppenoid acids, alcohols, lactones, phenols, and alkaloids have been obtained from a variety of sources. The hydrocarbons are more restricted in occurrence; all are found in New Zealand and all but two (camphorene and cupressene) in endemic species. Their reported occurrences are almost solely limited to countries bordering on the Pacific.Scanned from print thesisenItems in ResearchSpace are protected by copyright, with all rights reserved, unless otherwise indicated.https://researchspace.auckland.ac.nz/docs/uoa-docs/rights.htmThesisFields of Research::250000 Chemical SciencesCopyright: The authorQ112835093
