中文摘要:
      按国家标准方法分析测定了木姜花种子油的理化指标；采用气相色谱-质谱联用方法对木姜花种子油脂肪酸组成进行了测定。结果表明：木姜花种子含油率为26.82%；木姜花种子油相对密度为0.928 9，折光指数为1.482 2，酸值（KOH）为1.92 mg/g，过氧化值为6.20 mmol/kg，碘值（I）为190.5 g/100 g；木姜花种子油含不饱和脂肪酸88.96%，饱和脂肪酸11.04%，其中α-亚麻酸含量为53.92%，亚油酸含量为26.61%，油酸含量为8.22%，棕榈酸含量为7.75%，硬脂酸含量为2.93%，花生酸含量为0.31%，花生一烯酸含量为0.10%，棕榈油酸含量为0.06%，花生二烯酸含量为0.05%，山嵛酸含量为0.05%。
英文摘要:
      The physicochemical index of Elsholtzia cypriani seed oil was analyzed by national standard method, and the fatty acid composition of Elsholtzia cypriani seed oil was analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that the oil content of Elsholtzia cypriani seed was 26.82%. The relative density, refractive index, acid value, peroxide value and iodine value of Elsholtzia cypriani seed oil were 0.928 9, 1.482 2, 1.92 mgKOH/g, 6.20 mmol/kg and 190.5 gI/100 g, respectively. The contents of unsaturated acid and saturated acid in Elsholtzia cypriani seeds oil were 88.96% and 11.04% respectively, in which the contents of α-linolenic acid, linoleic acid, oleic acid, palmitic acid, stearic acid, arachidic acid, eicosenoate acid, palmitoleate, eicosadienoic acid and docosanoic acid were 53.92%,26.61%, 8.22%, 7.75%, 2.93%, 0.31%, 0.10%, 0.06%,0.05% and 0.05%, respectively.
