Decumbic acid derivatives from soil fungus <i>Lasiodiplodia</i> sp. BG1083

Phytochemical analysis of <i>Blumea megacephala</i> root soil fungus <i>Lasiodiplodia</i> sp. BG1083 led to the isolation of four decumbic acid derivatives, including a new one phenylethyl ester of decumbic acid (1) and a jasmonic acid analogues, lasiodiplodin acid A (5). Decumbic acid (3) showed the weak antimicrobial activity against <i>Candida albicans</i> with Minimum inhibitory oncentration (MIC) of 128 μg/mL. Lasiodiplodin acid A (5) showed the weak activity against <i>Staphylococcus aureus</i> with MIC of 256 μg/mL.
