Por otro lado, se aplicó un método rápido para identificar a otros compuestos. De estos dos métodos se identificó a 19 ácidos grasos, 4 esteroles, y 15 compuestos lipídicos (esteres, alcoholes, alcanos, etc.).]]></p></abstract>

A gaseous chromatographic analysis was carried out, which allowed us to identify the fatty acids and sterols, for which an organic extract was made, applying a classical method. A rapid method was applied to identify other compounds. These two methods, 19 fatty acids, 4 sterols, 15 lipid compounds (esters, alcohols, alkanes, etc.) were identified.]]></p></abstract>
