| 摘 要： | 以毛竹叶为实材,利用同时蒸馏萃取法(SDE)提取毛竹叶中挥发油,挥发油中醇类化合物占36.31%,羧酸类化合物占30.3%,烷烃类化合物占15.46%,酮类化合物占8.04%,醛类化合物占3%。选取革兰氏阳性菌(枯草杆菌)、革兰氏阴性菌(大肠杆菌、假单胞杆菌、黄杆菌)和酿酒酵母等常见菌作为毛竹叶挥发油抑菌作用的测试菌株,同时考察了该挥发油对大肠杆菌和枯草杆菌的最低抑菌浓度(MIC)。结果显示,毛竹叶挥发油对大肠杆菌、枯草杆菌、假单胞杆菌、黄杆菌和酿酒酵母都有较强的抑菌活性,毛竹挥发油对大肠杆菌和枯草杆菌的MIC均为2.25mg/mL。

| Abstract: | The bamboos leaves collected from Phyllostahys heterocyla were pretreated with simultaneity distillation extraction(SDE).The alcohol compounds of the volatile oil account for 36.31%,the carboxylic acid compounds 30.3%,paraffinss compounds 15.46%,the ketones compounds 8.04%,and the aldehydes compounds 3%.One Gram-positive(Bacillus subtilis),four Gram-negative(Escherichia coli,Pseudomonas fluorescens SHL5,SHL7,Flavobacterium SHL45)and three fungi(Saccharomyces cerevisiae Ja 64,Tokay,Y 8)were selected as the t... |
