Abstract

From Phomopsis sp.(68-GO-164) three new cytochalasans named cytochalasins N, O, and P were isolated, besides the four known cytochalasans, cytochalasins H and J and epoxycytochalasins H and J. The structures of the new compounds were determined by spectral analysis, especially by NMR, and by correlation reactions with known compounds.
