The alkaloidal content of the bark of D. micrantha collected in various localities and at different times varies considerably. Samples from Queensland contained mainly micranthine, but daphnoline and daphnandrine were also found in barks from New South Wales. The bark of D. tenuipes, a species found in northern New South Wales, yielded repanduline, aromoline, and a new alkaloid tenuipine; the leaves yielded a de-N-methyltenuipine. An examination of D. repandula for minor alkaloids led to the isolation of O-methylrepandine and repandinine, probably identical with (±)-tenuipine; D. dielsii similarly examined yielded O-methylrepandine, repandinine, and tenuipine. The structure of the new alkaloids is discussed.
