Abstract

Detailed GC and GC-MS analyses of oil of Melaleuca have identified several constituents not previouslyreported from Melaleuca alternifolia and clarified some earlier assignments. The range, mean, andcoefficient of variation for the principle constituents in 800 typical samples are presented along withthe compositions of several substandard oils. Isolation and storage procedures affecting the chemicalcomposition of the oil are reported. Ethanolic extraction of mature leaves gave solutions suitable fordirect injection into a gas chromatograph for the qualitative determination of tea tree oil. Comparisonwith conventional steam distillation showed that this technique was suitable for preliminary analysisof tea tree oil yield and quality.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
