Resumo(s)
The fixed oil extracted from Laurus spp. fruit from
Madeira Island, Portugal, is used in local traditional medicine for
a wide variety of health complaints. Physical properties, density
and refractive index, as well as the TAG FA composition, sterols,
and waxes were determined. The oil was found to have an un usually high content of volatiles (ca. 10%), with trans-ocimene
and germacrene D predominating. Oleic (30%) and linoleic
(20%) acids were the main unsaturated FA, whereas lauric (18%)
and palmitic (up to 22.5%) acids were the main saturated FA in
the neutral lipid fraction. The oil had a sterol content on the same
order as olive oil, with β-sitosterol (84%) predominating. Two
sesquiterpene lactones, dehydrocostuslactone and costunolide,
accounted for 5% of the overall composition. Madeira laurel oil
is not currently used as an edible oil because of its very strong
flavor. Its claimed medicinal properties have not yet been vali dated, and this is the first report on the characterization of the
commercial product.
