| 摘 要： | 目的:分析比较采用超临界CO2流体萃取法与水蒸气蒸馏法提取的太子参提取物中挥发性化学成分的异同。方法:使用水蒸馏提取法和超临界CO2萃取技术从太子参中提取挥发性成分,用归一化法测定其百分含量。用气相色谱-质谱(GC-MS)计算机联用技术分离鉴定其中的化学组成。结果:太子参超临界CO2流体萃取物中初步鉴定了33种成分,主要成分为:亚油酸乙酯(28.70%)、n-十六酸(23.12%)、3-糠醇(5.51%)等;水蒸气蒸馏法提取挥发油初步鉴定了17种成分,主要成分为2-丙基呋喃(22.45%)、3-糠醇(19.78%)、3-乙基-3-甲基戊烷(19.47%)。结论:2种方法提取的挥发油化学成分差异较大,超临界CO2流体萃取法提取的挥发油能更真实、全面地反映太子参药材中的化学成分。
