| Abstract: |
| NMR was used to determine the oil contents of seed and seed kernel in 21 germplasms of Xanthoceras sorbifolia Bunge., and the fatty acid composition and relative contents in seed oil and seed kernel oil extracted use Soxhlet method were analyzed by GC-MS/MS. The results showed that the germplasm with oil contents of seed more than 35% were 09-12 (37.18%) and 09-09 (35.36%), and oil contents of seed kernel more than 65% were Chifeng Balinyouqi (65.78%) and 09-09 (65.74%). Ten kinds of fatty acids were detected from seed oil and seed kernel oil, including palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, peanut-enoic acid, peanut-dienoic acid, peanut-quinenoic acid, erucic acid and nervonic acid. The nervonic acid contents in seed kernel oil extracted with Soxhlet method were more than 3% in seven germplasms, and 12-09 was the highest(3.77%). A scientific basis for Xanthoceras sorbifolia Bunge. breeding and a reference for oil process were provided. |
