Journal ArticleDOI
Chemistry of the annonaceae, Part 29. Structure of mezzettiaside-2, -4, -5, -6 and -7, new partially esterified 1-O-octyl tri- and tetra-rhamnosyl derivatives from Mezzettia leptopoda
Joseph T. Etse,Alexander I. Gray,Catherine Lavaud,Georges Massiot,Jean-Marc Nuzillard,Peter G. Waterman +5 more
TL;DR: Mezzettia leptopoda (Annonaceae) has been characterized using NMR and MS studies, which led to the characterization of mezzettiasides-2, -4, -5, -6, -7 and -7 from the stem bark of the leptopsia as mentioned in this paper.
Journal ArticleDOI
Microcybin : a novel dimeric coumarin from Microcybe multiflorus and Nematolepis phebalioides
TL;DR: A novel dimeric 3-prenylated coumarin 1 has been isolated from the aerial parts of two species of Rutaceae, Microybe multiflorus and Nematolepsis phebalioides, to which the trivial name microcybin is assigned.
Journal ArticleDOI
The extraction, isolation and identification of the purgative component of Croton penduliflorus seed oil.
TL;DR: The purgative principles in Croton penduliflorus seed oil were isolated as white crystals by a bioassay-guided chromatographic separation process and identified as a mixture of palmitic, stearic and arachidic acids in approximately equimolar concentration.
Journal ArticleDOI
A method for the determination of substitution pattern in coumarins using a lanthanide shift reagent
TL;DR: The n.m.r. shift reagent tris-(7,7-dimethyl-1,1, 1,2, 2,3,3-heptafluoro-octane-4,6-dionato)Europium(III)[Eu(fod)3] complexes with the carbonyl oxygen of coumarins so that all shifts can be related to a position for the europium atom in the plane of the ring and on the 3-H side of the CO bond; relatively large shifts are produced for
Journal ArticleDOI

TL;DR: The identification of bokkosin constitutes the first isolation of this class of compound from any natural source and establishes the compound as a potential trypanocide that, considering its novelty, should now be tested for activity against other microorganisms as well.
