    摘要: Known cyclic depsipeptides which are PF 1022F substance and PF 1022H substance, as well as a novel cyclic depsipeptide, PF 1022G substance, are now prepared simultaneously by cultivating a fungal strain capable of producing PF 1022F substance, PF 1022G substance and PF 1022H substance represented by the known PF 1022 strain (deposited under FERM BP-2671) which is a kind of fungus belonging to asporous imperfect fungi (the order Agonomycetales) and is presumable to belong to the genus Xylaria or the genus Rosellinia in the family Xylariaceae. The PF 1022G substance has the formula: ##STR1##
