目的:分析宽叶金粟兰挥发油的主要化学成分及其抗氧化活性。方法:采用水蒸气蒸馏法获得宽叶金粟兰挥发油,运用气相色谱-质谱联用进行成分分析,同时运用紫外分光光度计测定其对1,1-二苯基-2-三硝基苯肼(DPPH)自由基的清除能力以及总还原能力。结果:从宽叶金粟兰的挥发油中鉴定了21个化合物,占总量的82.30%;挥发油具有较好的还原能力,但对DPPH自由基的清除能力较弱。结论:宽叶金粟兰挥发油主要成分为乙酸冰片酯(45.43%)、3-亚甲基-2-降冰片酮(12.36%)、莰烯(8.74%)等,挥发油具有一定的抗氧化活性。［Abstract］ Objective: This article aimed to study the chemical components of essential oils from
Chloranthus henryi and their antioxidant activity． Method: The essential oil was extracted by steam distillation，
and its constituents were identified by GC-MS． The antioxidant activity of the essential oil was evaluated on its
ability of total reducing and scavenging of 1-diphenyl-2-picrylhydrazy ( DPPH) free radical by spectrophotometry．
Ｒesult: Twenty-one compounds，accounting for 82. 30% of the essential oil，were identified． The ability of
scavenging DPPH free radical of the essential oils was weak，while the total reducing ability was strong．
Conclusion: The main chemical constituents of the essential oil from C． henryi were bornyl acetate ( 45. 43%) ，3-
methylene-2-norbornanone ( 12. 36%) and camphene ( 8. 74%) ． And the essential oil showed some antioxidant
activity．广西高校科学技术研究项目(YB2014100
