%X Unstable 2-methylaminoethyl esters from E. chlorostachys can be isolated with careful pH control and then manipulated as their stable hydrochlorides. A large-scale extraction and counter- current distribution separated two new crystalline alkaloid hydrochlorides, namely norerythrostachaldine hydrochloride, C23H37NO5,HCl, and a second salt, C24H37NO7,HCl. Four new monoacetates are tentatively identified as the 3&#946;-acetoxy derivatives of the two new alkaloids, norerythrostachamine, and norerythrophlamine. Norerythrophlamine has been isolated for the first time as its crystalline hydrochloride.
