| 摘 要： | 利用顶空固相微萃取（HS-SPME）结合气相色谱-质谱联用仪（GC-MS）分析鱼腥草浸泡酒中香味成分以及紫外分光光度计（uv）测定其多酚含量及1，1-二苯基-2-三硝基苯肼（DPPH）自由基清除能力。结果表明，主要香味成分为羧酸及羧酸酯、醇类、萜类以及醛酮类物质，其中己酸乙酯占检出成分的66．94％，丁酸乙酯（6．55％），月桂烯（4．51％），戊酸乙酯（2．00％），并检测出药理学活性的甲基正壬酮和乙酰龙脑等物质；多酚含量为1．92mg／mL，自由基清除率为62．00％。结果表明，因鱼腥草有较独特的化学以及丰富的营养成分，使得鱼腥草浸泡酒具有较丰富的营养及药理成分物质，具有一定的保健功能。 |

| Abstract: | Phenolics content in Houttuynia cordata Thunb steeping liquor was measured and its DPPH radical removal capacity was evaluated by HS-SPME coupled with GC-MS.The results showed that main flavoring compositions of Houttuynia cordata Thunb steeping liquor were carboxylic acids and carboxylic esters,alcohols,terpene,aldehydes and ketone including ethyl caproate(66.94 %),ethyl butyrate(6.55 %),myrcene(4.51 %) and ethyl valerate(2.00 %).Besides,some bioactive compositions such as.2-undecanone and bornyl acetate were detected.The content of phenolics was 1.92 mg/mL and DPPH radical removal capacity was 62 %.This study proved that Houttuynia cordata Thunb contains specific chemical compositions and rich nutrients,which makes healthcare functions of Houttuynia cordata Thunb steeping liquor. |
