绿僵菌SC0924酚酸类代谢产物及其抗荔枝霜疫霉活性

Phenolic Acids from Metarhizium sp. SC0924 and Their Antifungal Activity against Peronophythora lichii

摘要:

从绿僵菌SC0924固体发酵物中分离得到8个酚酸类化合物，通过波谱分析，分别鉴定为香草酸(1)、丁香酸(2)、邻氨基苯甲酸(3)、苯乙酸(4)、阿魏酸(5)、二氢阿魏酸(6)、2-羟基-3-苯丙酸(7)和2-羟基-3-对羟基苯丙酸丁酯(8)。以滤纸片琼脂扩散法对以上化合物进行抗荔枝霜疫霉活性试验，结果表明除化合物2和6外，其余化合物均有抑菌活性。

Abstract:

Eight phenolic acids were isolated from the solid cultures of Metarhizium sp. SC0924. They were identified as vanillic acid (1), syringic acid (2), anthranilic acid (3), phenylacetic acid (4), ferulic acid (5), dihydroferulic acid (6), 3-phenyllactic acid (7) and latifolicinin A (8). All compounds except 2 and 6 exhibited antifungal activities against Peronophythora litchii by the agar diffusion method using paper disks.
