| 测定分析了纸皮、双软、晚丰、浓帕烈4个品种巴旦木种仁在不同采收期的粗脂肪含量及其油脂脂肪酸组成。结果表明：不同品种巴旦木采收过程中，其种仁粗脂肪含量总体均呈不断积累上升趋势，粗脂肪含量差异显著（p＜0.05），表明采收期对粗脂肪含量有较大影响，种仁越成熟越有利于其粗脂肪的积累；不同采收期的4个品种巴旦木种仁油共检测出棕榈酸、硬脂酸、油酸、亚油酸4种脂肪酸，其中饱和脂肪酸含量在10%以下，总体均呈下降趋势，不饱和脂肪酸的含量达90.4%~93.2%、油酸含量（58.9%~77.6%）均为最高，在采收期内总体均呈上升趋势；亚油酸含量（15.2%~31.7%）较高，在采收期内总体呈波浪下降趋势（除纸皮巴旦木）。巴旦木是一种具有很高开发价值的高品质油料作物。 |

| The crude fat contents and oil fatty acid compositions of four species of almond kernel in different harvest time were determined and analyzed. The results showed that the crude fat contents in different species of almond kernel were accumulating and rising, and the difference in the crude fat contents was significant(p＜0.05), indicating that the harvest time had a great influence on the crude fat content of amond kernel, and the more mature the kernel, the better the accumulation of crude fat. Four fatty acids were detected in the four species of almond kernel oils in different harvest time, which were palmitic acid, stearic acid, oleic acid and linoleic acid. The contents of saturated fatty acids were lower than 10% with overall a downward trend, and the contents of unsaturated fatty acids were in the range of 904%-93.2%. The contents of oleic acid（58.9%-77.6%）were the highest, and showed an upward trend. The contents of linoleic acid（15.2%-31.7%）were higher, and showed a downward trend (except Prunus amygdalus). Almond was a high quality oil crop with high development value. |
