Abstract: All of the carbon signals of ajugasterone C(1)were labeled as compared with the carbon signals of rhapontisterone(2) and ponasterone A(3), respectively.The mistakes, which were made in the belonging of proton signals of this compound in the literature, were corrected by the techniques of 1H-1H COSY and 13C-1H COSY.

Key words: Ajugasterone C, Spectral specificity, Phytoecdysteroid
