Chemical Characterization of Metabolites from the Husk of Theobroma cacao by GC-MS in Cuba

Danae Perez, José González, Enrique Gómez, Julio Perez, José L. Rodríguez, Max Monan


n ethanolic extract at 90% made by Soxhlet was analyzed using a Shimadzu spectrometer coupled to gas chromatography (GCMS-QP2010 Ultra) after derivatization with BSTFA from the husk of Theobroma cacao. The drug powdered was evaluated through a phytochemical screening to get information about the chemical components present in the sample. Ethereal, ethanolic and aqueous extract were analyzed by the same GCMS technique. Gas Chromatography Mass Spectrometry (GC-MS) analysis revealed the presence of 74 metabolites from this husk. According to NIST21 and NIST107 Libraries Databases some of the phyto-compounds screened were Caffeine, Theobromine, Catechine, Uridine, Stigmasterol, Cholesterol and Androstane-11,17-dione,3-[(trimethylsilyl)oxy]-,17-[O-(phenyl methyl)oxime]. Phytochemical screening revealed the possible presence of fats, alkaloids, triterpenes and steroids, catechins, reductants sugars, saponins, phenolic compounds, aminoacids or amines, quinones, anthocyanidins, flavonoids and bitter or astringent principles.
