Sur la constitution de la Dioscorine

Abstract: II y a quelque temps j'ai publik dans les Annales du Jardin Botanique de Buitenzorg 1) lee rhsultats prkliminaires de recherches sur la Dioscorine, l'alcalo'l'de toxique de la D i o s c CI r e a h i r 8 u t a B 1. Depuis, j'ai ponrsuivi ces recherches, et je me propose de donner ici un expose detail16 des experiences qni m'ont permis d'dlucider la constitution de cette substance.Les tubercules de la D i o s c o r e a h i r s n t a Bl.,connusA Java sous le nom de ,gadoeng", sont assez frkquemment employks comme… Show more

“…28 A compound with similar structure but with unknown C-14 stereochemistry has been reported earlier from A. paniculata 10 and as a metabolite of andrographolide in rats. 28 The spectroscopic data reported are in good agreement with those observed by us for andropanolide (1), which settles the structure of these products. The methyl group at C-10 (supposed to be R as in case of andrographolide) showed a strong NOE interaction with H-12; the latter must therefore be R-oriented.…”
