Mycelial Constituents of Oospora sulphturea-ochracea Part II

Abstract

(1) The substance B, one of the mycelial constituents ofOospora sulphurea-ochracea, was investigated on its structure and as one of breakdown products a methylxanthene was isolated. The structural relation of B to xanthone was suggested.
(2) The structural connection between A and B was discussed basing upon experimental facts.
(3) The isolation of some more crystalline constituents was recorded, thus hitherto isolated crystalline compounds from this mould amounting to 7 in all.
