Among the numerousbotanical 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 skininfections, hemorrhoids, stomach ulcers, gastric pain, among others. In thiswork, hexane and ethanolic extracts of X.americana seeds were subjected to silylation reactions followed by analysisof the silylated derivatives by gas chromatography-mass spectrometry GC-MS.In the hexane extract, 18 substances were identified, where the most abundantand most important components were the Octadec-9-enoic 38.14%, 9Z,12Z-Octadec-9,12-dienoic18.83%, Ethanedioic 8.21% and Z,Z,Z-9,12,15-Octadecatrienoic7.22% acids. From the ethanol extract 18 substances were also identified havingD-Sucrose 29.36%, L-Sorbose 9.19%, syllo-Inositol 8.34% and D-Glucose7.45% as the main components. In addition, the presence of a steroid inhexane extract and triterpenes in ethanol extract was recorded. The constituentswere identified using chromatographic and spectrometric methods, especially gaschromatography-mass spectrometry. To our knowledge, this is the first studyof this nature from the oil of the X. american seeds.
