- BIS-BENZYLISOQUINOLINE ALKALOIDS FROM ABUTA PAHNI
-
From the stems of Abuta pahni, eight isoquinoline alkaloids were isolated and identified by spectroscopic methods and chemical correlations.Three of the bis-benzylisoquinoline alkaloids are new and were assigned the structures 2'-N-nordaurisoline, 2-N-methyllindoldhamine and 2'-N-methyllindoldhamine.The other known alkaloids were coclaurine, daurisoline, lindoldhamine, dimethyllindoldhamine, stepharine and thalifoline. - Key Word Index: Abuta pahni; Menispermaceae; bis-benzylisoquinoline alkaloids; 2'-N-nordaurisoline; 2-N-methyllindoldhamine; 2'-N-methyllindoldhamine.
