芡欧鼠尾草脂肪酸成分分析

Oil Content and Fatty Acid Composition of Salvia hispanica L.

2006年引进芡欧鼠尾草作为新种质,组培脱毒后收种,通过连续3年的引种驯化,芡欧鼠尾草在湖南地区能顺利完成其生育期。为了解引种对其种子和营养器官中脂肪酸成分及含量的影响,对芡欧鼠尾草原种种子、引种第1代种子、引种第2代种子及各生长期茎叶干物质中脂肪酸按GB/T 17377—1998标准进行了全面分析。结果表明引种到我国的芡欧鼠尾草种子中亚麻酸含量高达195.39 g/kg,占总脂质的60%以上,与原种相比没有显著差异,是一种极有潜力的绿色食品原料;检测还发现其茎叶干物质中含亚麻酸达6.38g/kg,即该品种还可开发为新型动物饲料,以获得富含DHA的动物制品。

As a new germplasm, Salvia hispanica L. was introduced to Hunan for the first time in 2006. After detoxification by tissue culture, the nontoxic seeds were harvested. Salvia hispanica L. could pass whole growth period in Hunan by continuous acclimatization from 2007 to 2009. Compositions and contents of Fatty Acid from seeds and vegetative organs were tested as per GB/T 17377--1998. The results showed ：Salvia hispanica L. seeds harvested in 2008 and 2009, contained 195.39 g/kg linolenic acid in average, which occupied more than 60% in the content of total lipids. Compared with original seeds, it was obvious that there was no significant difference. Meanwhile, it appeared that this new germplasm could be thought as one potential green -food in future. In addition, studies presented that dry matter of vegetative organs contained 6.38 g/kg linolenic acid. In other words ,this variety also could be cultivated as one new - type animal food in order to obtain abundant DHA.
