Chemical study of the nematicidal biocontrol fungus Pochonia chlamydosporia PC-170 led to discovery of six resorcylic acid lactones (RALs), including three nematicidal glycosylated RALs, monocillin VI glycoside (1) , colletogloeolactone A (2) and monocillin II glycoside (3) , and three antibacterial non-glycosylated RALs, monocillin VI (4) , monocillin IV (5) and monocillin II (6) . The planar structure of the new compound monocillin VI glycoside (1) was elucidated using HRESIMS and NMR data, and its monosaccharide configuration was further determined through sugar hydrolysis experiment and GC-MS analysis method...
