ABSTRACT: Among the numerous
botanical species found in the Brazilian plant biome, Ximenia americana is widespread in the Northeast of Brazil,
especially in the state of Ceará, where it is known as bush plum. Its bark,
leaves and roots are used in popular medicine for the treatment of skin
infections, hemorrhoids, stomach ulcers, gastric pain, among others. In this
work, hexane and ethanolic extracts of X.
americana seeds were subjected to silylation reactions followed by analysis
of the silylated derivatives by gas chromatography-mass spectrometry (GC/MS).
In the hexane extract, 18 substances were identified, where the most abundant
and most important components were the Octadec-9-enoic (38.14%), (9Z,12Z)-Octadec-9,12-dienoic
(18.83%), Ethanedioic (8.21%) and (Z,Z,Z)-9,12,15-Octadecatrienoic
(7.22%) acids. From the ethanol extract 18 substances were also identified having
D-Sucrose (29.36%), L-Sorbose (9.19%), syllo-Inositol (8.34%) and D-Glucose
(7.45%) as the main components. In addition, the presence of a steroid in
hexane extract and triterpenes in ethanol extract was recorded. The constituents
were identified using chromatographic and spectrometric methods, especially gas
chromatography-mass spectrometry. To our knowledge, this is the first study
of this nature from the oil of the X. american seeds.
