对1株富产吲哚喹唑啉类生物碱(IQAs)的海绵共附生真菌
Aspergillus
giganteus
MA 46-5的IQAs类成分进行了研究。根据IQAs的结构特征,在TLC、LC-MS和GNPS(global natural products social molecular networking)技术的共同指导下,从大米培养基的乙酸乙酯部位分离得到10个IQAs类生物碱。通过NMR、HR-ESI-MS、OR和CD等方法并结合文献比对鉴定其分别为:tryptoquivaline(
1
)、nortryptoquivaline(
2
)、deoxytryptoquivaline(
3
)、deoxynortryptoquivaline(

According to the structure feature of indole quinazoline alkaloids(IQAs),under the guidance of TLC,LC-MS and GNPS(global natural products social molecular networking),IQAs from sponge-associated fungus
Aspergillus giganteus
MA 46-5 were studied and ten IQAs were isolated from rice medium of MA 46-5. Based on NMR,HR-ESI-MS,OR,CD and comparison with the literature,their structures were determined as tryptoquivaline (
1
),nortryptoquivaline (
2
),deoxytryptoquivaline (
