摘要
本文以长白山宽叶杜香为研究对象,采用水蒸气蒸馏法提取杜香挥发油,利用GC-MS分析挥发油化学组成,并对其抗氧化活性及抑菌活性进行分析。结果:从长白山杜香挥发油中鉴定出32种化学成分,主要成份为β-水芹烯(43.55%),萜烯醇(11.86%)等,杜香挥发油抗氧化活性为Vc的4.16倍,并对大肠杆菌、金黄葡萄杆菌及枯草芽孢杆菌均具有抑菌作用。结论:杜香中挥发油含量较高,有较强的抗氧化及抑菌活性,可作为天然抗氧化剂和抑菌剂来源。
Using steam distillation method,the volatile oil was extracted from Ledum palustre L.,its chemical compositions were analyzed by GC-MS.Finally,the antioxidant activity was detected by DPPH scav-enging method,and the antibacterial activity was examined using antibacterial ring and MIC method.Results:32 chemical constituents were identified from Ledum palustre L.volatile oil of Le-dum palustre L.,including beta-Phellandrene(43.55%),4-methyl-1-(1-methylethyl)-3-Cyclohexen-1-ol(11.86%),and so on.Antioxidant activity of the volatile oil was approximately 4.16 times of Vc.The volatile oil has inhibitory activity to Escherichia coli,Staphylococcus aureus and Bacillus subtilis.Conclusion:The volatile oil is abundant in Ledum palustre L.,and has stronger antioxidant and antimicrobial activity.Ledum palustre L.volatile oil can be used as a source of natural antioxidant and bacteriostat.
