Cordyceamides A and B from the Culture Liquid of Cordyceps sinensis (BERK.) SACC.

Two new aurantiamides named as cordyceamides A and B were isolated from the culture liquid of Cordyceps sinensis (BERK.) SACC., along with one known compound, aurantiamide acetate. Their structures were elucidated as N-benzoyl-L-tyrosinyl-L-phenylalaninol acetate and N-benzoyl-L-tyrosinyl-L-p-hydroxyphenylaolninol acetate by 1D, 2D-NMR techniques and comparison with literatures.
