摘    要:初步研究了地达菜中不同溶剂提取物,即石油醚、乙酸乙酯、丙酮、乙醇、甲醇和水等溶剂提取物,对大肠杆菌(Escherichia coli)、绿脓杆菌(P.aeruginosa)、互隔交链孢(Alternaria alternata)、青霉(Peniicillium sp)和粉红单端孢(Trichothecium roseum)等的抗菌能力。结果表明:较低极性的乙酸乙酯、丙酮提取液对细菌中的绿脓杆菌抑制效果好,出现明显的抑菌圈;高极性的甲醇、乙醇提取液对果蔬腐败菌(Alternaria alternata、Trichothecium roseum、Peniicillium sp)抑制效果好,出现明显的抑菌圈。

关 键 词:地达菜  不同溶剂提取物  抑菌

Abstract:Antimicrobial capability to Escherichia coli,P.aeruginosa,Alternaria alternata,Peniicillium sp and Trichothecium roseum were studied of different solvent extracts including petroleum ether,acetylacetic ester,acetone,ethanol,carbinol,water,etc. from Nostoc Commune Vauch. The results showed that:the lower polar ethyl acetate,acetone extracts could hold the growth of P.aeruginosa;the higher polar methanol and ethanol extracts could hold the growth of the mold such as Alternaria alternata,Peniicillium sp and Tr...
Keywords:Nostoc Commune Vauch    different solvent extracts  antimicrobial
