研究一株中华稻蝗内生真菌
Fusarium lateritium
ZMT01的代谢产物,采用大米培养基发酵真菌,色谱技术分离纯化单体,波谱分析鉴定结构,共从发酵物中分离鉴定了10个化合物:fusopoltide A (
1
)、fusopoltide B (
2
)、fusopoltide D (
3
)、solaniol (

)、
β
-sitosterol (

)和walterolactone A (
10
)。其中化合物
8
、
10
为首次从
Fusarium
属中得到,除化合物
9
外,其他化合物为首次从
Fusarium lateritium
中分离到。采用二倍稀释法测试抗菌活性,结果显示化合物
4
和
5
对O6血清型大肠杆菌
Escherichia coli
有强抑制活性,MIC为6.25 µg/mL,化合物
4
对尖孢镰孢菌
Fusarium oxysporum
显示中等抑菌活性,MIC为200 µg/mL。
The metabolites of an endophytic fungus
Fusarium lateritium
ZMT01 from
Oxya chinensis
Thunbergwere investigated. The fungus was cultured in rice medium, the monomeric compounds were isolated and purified by the chromatographic technique, and the structures of compounds were identified by analysis of spectroscopy. Ten compounds were isolated and identified as fusopoltide A (
1
), fusopoltide B (
2
), fusopoltide D (
3
), solaniol (
4
), javanicin (
5
), (1

), 2-hydroxymethyl-5-isopropoxy-4-methoxynaphthalen (
8
),
β
-sitosterol (
9
) and walterolactone A (
10
). Among them, compounds
8
and
10
were firstly obtained from the genus
Fusarium
, and all of them except compound
9
were isolated from
Fusarium lateritium
for the first time. The antibacterial activities of these compounds were tested in vitro using the two-fold dilution method. Compounds
4
and
5
showed a high inhibitory activity against
Escherichia coli
with serotype O6 with MIC of 6.25 µg/mL, and compound
4
showed a moderate inhibitory activity against
Fusarium oxysporum
with MIC of 200 µg/mL.
