Publication Metadata only X-ray crystal and molecular structure of nirurine, a novel alkaloid related to the securinega alkaloid skeleton, from Phyllanthus niruri (Euphorbiaceae)(1986-12-01) Prapaisri Petchnaree; Nuntavan Bunyapraphatsara; Geoffrey A. Cordell; Heather J. Cowe; Philip J. Cox; R. Alan Howie; Steven L. Patt; Mahidol University; University of Illinois at Chicago; Robert Gordon University; University of Aberdeen; Varian, Inc.Nirurine, an alkaloid from the aerial parts of Phyllanthus niruri L. (Euphorbiaceae), was shown by single-crystal X-ray crystallography to possess the structure (2). Through extensive decoupling experiments a complete n.m.r. assignment of all of the protons and carbons in nirurine has been achieved.
