One of four very similar peptide alkaloids present in the bark of Zizyphus mucronata Willd., this base yields colourless needles when crystallized from CH2Cl2-light petroleum or CHC13-Et20. It is laevorotatory with [α]²⁰_D - 28.3° (c 0.06, CHC13) and the ultraviolet spectrum in MeOH has absorption maxima at 217 (shoulder) and 273 mp..

ChEBI: Mucronine A is a cyclic peptide.
