对甘肃地区43份胡麻资源的粗脂肪含量和脂肪酸各组分含量进行测定分析。结果表明，来自甘肃地区的43份胡麻资源粗脂肪含量的变化范围为33.46～416.80 g/kg，平均含量为207.72 g/kg，变异系数为86.96%。其棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸等不饱和脂肪酸的平均含量分别为58.60、49.80、272.80、144.80、478.30 g/kg，各指标变异系数的变化范围为11.55%～98.10%，其中以硬脂酸的变异系数最大，亚麻酸的变异系数最小。综合分析认为，胡麻中的脂肪酸含量由高到低依次为亚麻酸、油酸、亚油酸、棕榈酸、硬脂酸，变异系数由高到低依次为硬脂酸、粗脂肪、油酸、棕榈酸、亚油酸、亚麻酸。

The crude fat content and fatty acid component content of 43 flax resources in Gansu region were determined and analyzed. The results showed that the range of variation in crude fat content was from 33.46 g/kg to 416.80 g/kg， the average value was 207.72 g/kg， and the coefficient of variation was 86.96%. The average contents of the palmitic acid， stearic acid， oleic acid， linoleic acid and linolenic acid were 58.60， 49.80， 272.80， 144.80 and 478.30 g/kg， respectively. The range of variationof the unsaturated fatty acid was from 11.55% to 98.1% with the largest variation coefficient in stearic acid and the smallest one in linolenic acid. According to comprehensive analysis， the fatty acid content from high to low in turn for linolenic acid， oleic acid， linoleic acid， palmitic acid， stearic acid， coefficient of variation from high to low in turn for crude fat， stearic acid， oleic acid， palmitic acid， linoleic acid， linolenic acid.
