Abstract
New antibiotics, phthoxazolins B, C and D were isolated from the fermentation broth of Streptomyces sp. KO-7888. They are geometrical isomers of 10-hydroxyphthoxazolin A. They showed selective antifungal activity against Phytophthora parasitica in vitro and modest herbicidal activity in a laboratory test, but the potencies were different among isomers.Keywords
