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. |
