芫荽籽精油成分分析及消除亚硝酸钠能力研究

研究了黑龙江产芫荽籽精油成分和精油、残渣溶剂萃取物消除NaNO2的能力。用水蒸气蒸馏法提取黑龙江产芫荽籽,以0.50%的产率获得精油。用GC-MS对精油进行了成分分析,检测出31个成分,解析鉴定了占精油质量99.726%的29个成分。主要成分芳樟醇占73.614%(质量分数)。对NaNO2的消除作用结果显示:当精油用量为0.05～0.35mL时,消除率为47.0%～74.2%。水蒸气蒸馏后残渣的甲醇、乙醇、丙酮萃取物溶液用量为0.6～1.0mL时,对NaNO2的消除率为38.8%～42.2%。

Analysis of Chemical Components of the Coriander Seed Essential Oil and Its Ability of Scavenging Sodium Nitrite

The chemical components of the coriander seed essential oil,extracts of the residue and the ability of scavenging sodium nitrite were studied.The essential oil was obtained in 0.50% yield from the coriander(Coriandrum sativum L.) seeds grown in Heilongjiang by steam distillation extraction method.Then the oil was analyzed by GC-MS,31 constituents were detected and 29 compounds which occupied 99.726%(mass fraction) of total constituents were identified.The most abundant compound was linalool(73.614%mass fraction).The essential oil had considerable effect of scavenging sodium nitrite.With 0.05～0.35 mL essential oil,the scavenging rates were 47.0%～74.2%.The scavenging rates of methanol,ethanol and acetone extracts of the residue were 38.8～42.2% when 0.6～1.0 mL of the extract solutions were used
