Structures of seven compounds were elucidated mainly by the use of spectroscopic methods, especially by detailed analyses of 〓 and 〓 NMR spectra with the aid of 2D NMR spectroscopy including 〓 COSY,〓 COSY, HMQC, HMBC, COLOC, and MS techniques including EI-, CI-, SI-, ESI-MS and HR-EI-MS. Stereochemical structures of some of them were also determined on the basis of results of their NOEDS, NOESY and coupling relation.
