Oil content and fatty acid composition were investigated on 12 castor varieties and strains by using the soxhlet extraction method and capillary gas chromatography. This was made to provide a reference and theoretical basis for castorbean breeding with high oil content, determine variability of seed compounds for breeding purposes, and broaden chemical material choices. Results revealed that crude fat percentage in seeds ranged from 18.91 to 35.84% with an average of 25.91%; the absolute content of ricinoleicacid varied between 171.65 g/kg and 314.03 g/kg with an averageof 222.43 g/kg, and kernel crude fat percentage was between 24.28 and 46.97% with an average of 34.30%. All these study variables were highest in the 2129 strain. The percentage of ricinoleic acid in crude fat was between 83.85 to 87.62%, and the highest value was found in the zhebi4 accession. The other fatty acids appeared in small concentrations, and showed small amplitude: 1.12 to 1.61%,1.21 to 1.61%, 3.53 to 4.80%, 5.35 to 6.38%, 0.52 to 0.79%, 0.05 to 0.08% and 0.43 to 0.55%, for palmitic, stearic, oleic, linolic, linolenic, arachidic, and arachidonic acids, respectively. One hundred seed weight was determined for each accession. One hundred seed weight ranged from 25.7 g to 34.0 g with an average of 29.9 g. There was a significant correlation between seed weight and oil content, but the correlation value was low (r=0.51). Cluster analysis by SSPS based on the content of fatty acid composition revealed that the accessions were divided into three independent clusters. These findings will clearly provide useful information for further research in breeding and utilization of castor oil.
Se investigaron el contenido de aceite y la composición de ácidos grasos en 12 variedades y cepas de Ricinus communis L. usando un método de extracción y cromatografía gaseosa capilar. Esto se realizó con el fin de proveer una base teórica y de referencia para el cruzamiento de Ricinus communis L. con un alto contenido de aceites, determinar la variabilidad de compuestos de semillas con propósitos de cruzamiento, y ampliar la elección de materiales químicos. El porcentaje de grasa cruda en las semillas varió de 18,91 a 35,84% con un promedio de 25,91%; el contenido absoluto de ácido ricinoleico varió entre 171,65 g/kg y 314,03g/kg, con un promedio de 222,43 g/kg. El porcentaje de grasa cruda del grano varió entre 24,28 y 46,97% con unpromedio de 34,30%. Los mayores valores para todas estas variables deestudio se obtuvieron en la cepa 2129. El porcentaje de ácido ricinoleico en la grasa cruda varió entre 83,85 a 87,62%, y el mayor valor se obtuvo en la variedad zhebi4. Los otros ácidos grasos aparecieron en menores concentraciones, y mostraron una pequeña amplitud: 1,12 a 1,61%; 1,21a 1,61%; 3,53 a 4,80%, 5,35 a 6,38%, 0,52 a 0,79%, 0,05 a 0,08% y 0,43 a 0,55%, para los ácidos palmítico, esteárico, oleico, linoleico, linolénico, araquídico y araquidónico, respectivamente. Se determinó el peso decien semillas para cada variedad. Dicho peso varió de 25,7 g a 34,0 gcon un promedio de 29,9 g. Hubo una correlación significativa entre elpeso y el contenido de aceite de la semilla, pero con un bajo coeficiente de correlación (r=0,51). El análisis de grupos usando SSPS basado en el contenido de la composición de ácidos grasos mostró que las variedades se dividieron en tres grupos independientes. Estos resultados proveen claramente una información muy útil para futuras investigaciones sobre el cruzamiento y la utilización de aceite de ricino.
