【摘要】：目的:研究紅樹(shù)林內(nèi)生真菌Aspergillus sp.085035的次級(jí)代謝產(chǎn)物。方法:采用柱色譜和半制備高效液相色譜技術(shù)對(duì)Aspergillus sp.085035的次級(jí)代謝產(chǎn)物進(jìn)行分離純化,并利用波譜數(shù)據(jù)和X-射線單晶衍射等方法鑒定化合物結(jié)構(gòu);采用MTT法對(duì)所得化合物進(jìn)行細(xì)胞毒活性檢測(cè)。結(jié)果:從紅樹(shù)林內(nèi)生真菌Aspergillus sp.085035的乙酸乙酯粗提物中分離得到9個(gè)化合物,分別鑒定為:13R-fumigaclavine C(1)、8'-O-methylasterric acid(2)、1,2-secotrypacidin(3)、rhizoctonic acid(4)、chaetominine(5)、helvolic acid(6)、trypacidin(7)、emodin-8-methylether(8)和fumitremorgin C(9)。結(jié)論:化合物1為新天然產(chǎn)物,化合物1、8為首次從曲霉屬中分離得到,所有化合物均為首次從該真菌中分離得到,化合物7對(duì)MDA-MB-435細(xì)胞株具有細(xì)胞毒活性。
[Abstract]:Objective: to study the secondary metabolites of endophytic fungus Aspergillus sp.085035 in mangrove forests. The secondary metabolites of Aspergillus sp.085035 were separated and purified by column chromatography and semi-preparative high performance liquid chromatography. The structures of the compounds were identified by means of spectral data and X-ray single crystal diffraction. The cytotoxic activity of the compounds was determined by MTT method. Results: the endophytic fungus Aspergillus from mangrove forests was used to detect the cytotoxicity of the compounds. Nine compounds were isolated from the ethyl acetate extract of sp.085035. They were identified as: 13R-fumigaclavine, Candellavine, 8- O-methylasterric acidine, respectively. 2-secoTrypacidinine 3 Rhizoctonic acidinine 4). Helvolic acidin7). Conclusion: compound 1 is a new natural product and compound 1 is a new natural product. 8 was isolated from Aspergillus for the first time and all compounds were isolated from the fungus for the first time. Compound 7 has cytotoxic activity to MDA-MB-435 cell line.
