目的:采用GC-MS分析容县八角叶挥发油的化学成分。方法:采用超声波辅助水蒸气蒸馏法快速提取容县八角叶挥发油,并通过GC-MS联用技术对挥发油中成分进行分析鉴定。结果:八角叶挥发油得率为1.65%,采用面积归一化法对挥发油成分进行定量分析,共鉴定出35个化合物,占挥发油总量的98.06%。结论:容县八角叶挥发油主要成分为反式茴香脑(71.69%),草蒿脑(5.00%),α-蒎烯(3.52%),顺式茴香脑(2.86%),丁香烯(1.56%),柠檬烯(1.37%),芳樟醇(1.29%)。
OBJECTIVE: To analyze the chemical constituents of volatile oil from star anise in Rongxian County by GC-MS. Methods: Volatile oil from leaves of Star angelica of Rongxian County was extracted rapidly by ultrasonic assisted steam distillation. The constituents of volatile oil were identified by GC-MS. Results: The yield of volatile oil from star aniseed was 1.65%. The area normalization method was used to quantitatively analyze the components of volatile oil. A total of 35 compounds were identified, accounting for 98.06% of the total. CONCLUSION: The main constituents of volatile oil from star anise of Rongxian County are trans-anethole (71.69%), Artemisia arborescens (5.00%), α-pinene (3.52%), cis-anisole (2.86%) and caryophyllene (1.56% ), Limonene (1.37%), linalool (1.29%).
