Abstract
The new isoquinoline alkaloid turcamine (1) has been isolated from the leaves ofBerberis turcomanica, and its structure has been established as 8-hydroxy-7-methoxy-2-methyltetrahydroisoquinoline. A relationship has been found between a substituent at C-8 and the multiplicities of the signals from C-5 and C-6.
