Extracts of Thalictrumrugosum were found to be reproducibly active against mycabacteria, the active agents were isolated, and four were identified to be bisbenzylisoquinolinealkaloids of known and unknown structure.
Abstract The structure of the new bisbenzylisoquinoine alkaloid, thalfoetidine, was established by means of sodium in liquid ammonia cleavage of O-ethylthalfoetidine. The nonphenolic base of this degradation was identified as d-O-ethylarmepavine thus fixing the position of the phenolic hydroxyl group present in the molecule of thalfoetidine. Further a phenolic base was isolated from the above degradation
