“…Many Leptospermum species are cultivated as ornamental plants and are often mistakenly identified as the source of TTO. In addition, the essential oils kanuka and manuka, derived from the New Zealand plants Kunzea ericoides and Leptospermum scoparium, respectively, are referred to as New Zealand TTOs (42) although they are very different in composition from Australian TTO (125). In this review article, the term TTO will refer only to the oil of M. alternifolia.…”

Melaleuca alternifolia(Tea Tree) Oil: a Review of Antimicrobial and Other Medicinal Properties

2006

View full text Add to dashboard Cite

SUMMARY Complementary and alternative medicines such as tea tree (melaleuca) oil have become increasingly popular in recent decades. This essential oil has been used for almost 100 years in Australia but is now available worldwide both as neat oil and as an active component in an array of products. The primary uses of tea tree oil have historically capitalized on the antiseptic and anti-inflammatory actions of the oil. This review summarizes recent developments in our understanding of the antimicrobial and anti-inflammatory activities of the oil and its components, as well as clinical efficacy. Specific mechanisms of antimicrobial and anti-inflammatory action are reviewed, and the toxicity of the oil is briefly discussed.

“…; In this group the seeds are linear and striate, the fruits woody and persistent, sepals are deciduous, stem anges are present, the hypanthium is pubescent or glabrous and the ovary is 4±5-locular. 8,9 Perry et al 10 and Porter et al 11 have reported the oil composition of populations from Australia and New Zealand, and found it to be quite variable. 3 Of this group, only L. scoparium has been chemically examined in any detail.…”

“…Most of the work has been carried out on New Zealand populations of this species, where it is more prevalent. The oil of L. continentale has been isolated, but rather confusingly Perry et al 10 included its compositional data with those of Australian L. scoparium, L. continentale and L. juniperinum. The b-triketone, leptospermone, had previously been found in the oil of this species.…”

The essential oils of a series of Leptospermum species belonging to Group 8 of our classification have been examined. L. micromyrtus Miq., L. minutifolium C.T. White, one chemotype of L. myrtifolium Sieber ex DC., L. rupestre Hook. f., and L. sejunctum Joy Thomps. produced oils rich in sesquiterpenes, α‐, β‐ and γ‐eudesmol being the most significant compounds. L. myrtifolium existed in two chemotypes, the second of which contained (E,Z)‐farnesal (5.8%), (E,E)‐farnesal (12.9%), 2,3‐dihydro‐(E)‐farnesol (10.3%) and (E,E)‐farnesol (26.5%) as its principal components. One chemotype of L. novae‐angliae Joy Thomps. contained (E)‐nerolidol (50%) as a major component, while L. rupicola Joy Thomps. contained α‐ and β‐pinene as principal components (totalling approximately 50%). L. continentale Joy Thomps., L. gregarium Joy Thomps., L. juniperinum Sm., a second chemotype of L. novae‐angliae, L. obovatum Sweet, both varieties of L. scoparium J. R. Forst & G. Forst. and L. squarrosum Gaertn. contained a mixture of mono‐ and sesquiterpenes, usually with the latter predominating. Copyright © 1999 John Wiley & Sons, Ltd.

“…This analysis indicated a link between the two triketone rich populations although they were spatially very distant. In a related study based on the analysis of L. scoparium grown from seed collected at 15 sites around the country, they identified three chemotypes, and determined that oil composition was largely genetically controlled (Perry et al, 1997).…”

Chemotypic variation of essential oils in the medicinal plant, Anemopsis californica

et al. 2008

Anemopsis californica (Saururaceae) commonly called yerba mansa, is an important medicinal plant in many deserts in the southwestern region of North America. Populations of A. californica, collected throughout New Mexico, were examined for chemical variability in roots and rhizomes for select monocyclic (cymene, limonene, piperitone and thymol) and bicyclic (α-pinene, 1,8-cineole and myrtenol) monoterpenoid and phenylpropanoid (methyleugenol, isoeugenol and elemicin) derived essential oil components. Three distinct chemotypes were detected using a hierarchical clustering analysis on the concentration of 10 different analytes in three individuals from each of 17 populations. One chemotype was characterized by high elemicin concentrations, a second chemotype by high methyleugenol concentrations and the third by high piperitone and thymol concentrations. Steam distilled oil was used to screen for anticancer bioactivity. A. californica root oils demonstrated antiproliferative activity against AN3CA and HeLa cells in vitro but no activity against lung, breast, prostate or colon cancer cells. The IC 50 values for the root oil were 0.056% and 0.052% (v/v) for the AN3CA and HeLa cells respectively.
