对红树植物桐花树内生真菌
Talaromyces
amestolkiae
30的次级代谢产物进行了研究。采用大米固体发酵培养,色谱分离技术纯化单体,ESIMS和NMR等波谱数据分析,鉴定了12个异香豆素单体化合物:aspergillumarin A(

The metabolites of the endophytic fungus
Talaromyces amestolkiae
30 from the mangrove plant
Aegiceras corniculatum
(L.) Blanco were investigated. The fungus was cultured in rice medium
the monomeric compounds were isolated and purified by the chromatographic technique
and the structures of the compounds were identified by analysis of spectroscopy such as ESIMS and NMR. Twelve known analogues of isocoumarins (
1
-
12
) were isolated and identified as aspergillumarin A (
1
)
aspergillumarin B (
2
)
5
6-dihydroxy-3-(4-hydroxypentyl)-isochroman-1-one (
3
)
mucorisocoumarin A (

)
peniisocoumarin G (
9
)
talumarin A (
10
)
5
6
8-trihydroxy-4-(1'-hydroxyethyl)-isocoumarin (
11
) and sescandelin (
12
). Among them
compounds
4
6
and
7
were obtained from the genus Talaromyces for the first time. The antibacterial activities of these compounds were tested in vitro using the twofold dilution method. Compounds
4
6
and
7
showed inhibitory activity against
Staphylococcus aureus
. The cytotoxic activity was tested by the MTT assay. Compound 7 showed cytotoxicity against prostate cancer PC-3 cells and VCaP cells.
