通过琼脂平板扩散试验和双倍稀释试验,对青木香(Aristolochia debillis Sieb. et Zucc.)的石油醚提取物、乙酸乙酯提取物和甲醇提取物进行了抗细菌和抗真菌作用的研究,在三种提取物中,只有甲醇提取物对试验的所有革兰氏阳性和革兰氏阴性细菌都表现出显著的抗菌作用,乙酸乙酯提取物只对测试的部分细菌显示出抗菌作用,石油醚提取物不具有抗菌活性.甲醇提取物比乙酸乙酯提取物具有更强的抗菌作用和更广的抗菌谱.三种提取物对所有试验的真菌都没有显示出抗菌作用.
The antibacterial and antifungal effects of Aetherlochia debillis Sieb. et Zucc.’s petroleum ether extracts, ethyl acetate extracts and methanol extracts were studied by agar plate diffusion and double dilution tests. Of the three extracts, only the methanol extract exhibited significant antibacterial activity against all gram-positive and gram-negative bacteria tested, and the ethyl acetate extract exhibited only an antibacterial effect on some of the tested bacteria. The extract had no antibacterial activity. The methanol extract had stronger antibacterial activity and broader antibacterial spectrum than the ethyl acetate extract. The three extracts showed no antibacterial effect on all tested fungi.
