| 摘 要： | 对土荆芥果实挥发油成分及抗氧化能力进行研究。采用质谱技术与Kovats指数相结合对土荆芥果实挥发油化学成分进行分离鉴定;利用清除1,1-二苯基苦基苯肼(DPPH)自由基的方法,评价土荆芥果实挥发油的抗氧化能力。土荆芥果实挥发油中分离鉴定了11种组分,其相对含量占挥发油总质量的98.94%,含量较高组分是α-异松油烯(60.44%),驱蛔素(15.57%),对-聚伞花素(12.76%)和α-松油烯(4.51%)。清除DPPH自由基IC50为6.9053mg.mL-1。土荆芥果实挥发油主要成分是萜烯类化合物;并具有一定的抗氧化能力。 |

| Abstract: | Essential oil in the fruit of Chenopodium ambrosioides L.and its antioxidant activity were studied.The essential oil was isolated and identified by GC-MS combined with Kvotas retention index,the antioxidant activity was screened by the method of scavenging 1,1-diphenyl-2-picryl-2-picrylhydrazyl（DPPH）free radical.11 components were isolated and identified from the essential oil in the fruit,accounts for 98.94% of the total oil,the main components were α-terpinolene（60.44%）,ascaridole（15.57%）,p-cymene（12.76%）and α-terpipene（4.51%）.The antioxidant activity IC50 value of essential oil was 6.9053mg·mL-1.Terpenes were the principal ingredients in the seed essential oil and exhibited antioxidant activity. |
