48% dillapiole in piper guineense leaf oil
« on: June 12, 2002, 12:09:00 PM »
"Dillapiole (44.8%), followed by myristicin (9.8%), were the
main constituents of P. guineense.
The essential oils were obtained by hydrodistillation of the
aerial parts (P. capense, P. guineense and P. umbellatum) and
fruits (P. nigrum). Yields were, respectively, 0.15, 0.10, 0.13
and 0.26%.
Despite the well known composition of the fruits of P. guineense
[4], to our knowledge this is also the first time that the compo-
sition of the oil from the leaves of this plant is given. Most of
the compounds that we have found in the leaf oil are also present
in the fruit oil. The major differences found are the percentage
of dillapiole (44.8% in the leaf and 0.09% in the fruit) and the
presence of safrole (4.8%) and sarisan (15.7%) in the fruit,
compounds that we have not found in the leaf oil."
