Novel Alkaloids from the Roots of Stemona sessilifolia
TLDR
Four new Stemona alkaloids, sessilistemonamines A–C (1–3, resp.) and dihydrostemoninine (4), were isolated from the roots ofStemona sessILifolia by means of in‐depth 1D‐ and 2D‐NMR‐spectroscopic as well as mass‐spectrometric experiments; and the structure of 4 was solved by X‐ray single‐crystal diffraction.
