THE ALKALOIDS OF EUPATORIUM MACULATUM L.

The root of Eupatorium maculatum L. has been examined and found to contain at least four alkaloids. The major base was found to be echinatine, while the second one in importance has been identified as the non-esterified trachelanthamidine. The remaining two alkaloids are probably also of the pyrrolizidine type, but their structures could not be determined due to paucity of material.
