Abstract

Three new hydroxyphenylacetic acid derivatives, stachylines E-G (1-3), and a new alkaloid, mortieridinone (4), along with six known compounds (5-10), were isolated from endophytic fungus Mortierella sp. in Epimedium acuminatum Franch. Their structures were determined by their spectroscopic analyses and by comparison with the literature data. Compounds 7 and 10 showed selective antibacterial activity against tested multidrug-resistant bacteria with minimum inhibitory concentration (MIC) values ranging from 25 to 3.13 mug/mL.
