摘要
Oil content from seed kernels of Xanthoceras sorbifolia from 13 areas in China was analyzed by gas chromatography–mass spectrometry to determine oil characteristics and biodiesel properties. The seeds had a high kernel percentage (53.67%± 7.51), oil content (52.21%± 4.01), and biodiesel yield (99.77%± 0.21). Among the fatty acids in the oil were high percentages of linoleic acid (41.66 ± 2.26)% and oleic acid (28.44%± 2.03). Most of the fuel properties complied well with the ASTM D6751-10, EN 14214-08, and GB/T 20828-2014 standards. The 13 sampling areas were grouped into four clusters based on different kernel percentage, oil content, biodiesel yield, and fatty acid composition. The results showed that the quality of kernel oils from seeds from Ar Horqin Banner was the best, although kernel oils from seeds in all 13 areas were suitable for biodiesel production. This study provides a basis for selecting optimal sites to harvest seeds from X. sorbifolia.
