Hernandia pyridine from

A few alkaloids with pyridine (XIII), proaporphine (XIV), and phenanthrene (XVI) nuclei were also found in the Hernandia, Gyrocarpus, and Illigera species, respectively (Table I). Phenanthrene alkaloids, also known as seco-aporphines, are a very rare type, probably formed biogenetically from an aporphine precursor through the opening of ring B (28). Castedo and Tojo have reviewed their chemistry (50). From the family Hernandiaceae only thaliporphinemethine (XVI.l) was isolated from I. pentaphylla Welw. (51).
