- 論文の詳細を見る
Three yellowish compounds with 1,1-diphenyl-2-picrylhydrazyl-radical scavenging activity were newly isolated from the fermentation broth of Trichoderma sp. USF-2690 strain that had been isolated from a soil sample : two were novel oxidized sorbicillin dimers designated as bisorbibutenolide (1) and bisorbicillinolide (2), and one was sorbicillin (3) itself. The structures of 1 and 2 were determined from spectroscopic evidence. In the DPPH-radical scavenging assay, α-tocopherol gave an ED_<50>value of 17.0μM after standing for 30 min, while continuing observation showed that the ED_<50> values for bisorbibutenolide, bisorbicillinolide, and sorbicillin slowly reached 80.8,88.8 and 152.3μM over 24 hr.
