The chemotaxonomic significance of the limonoid, nymania-1, in Turraea obtusifolia

Abstract

The genus Nymania has been chemotaxonomically linked to the family Meliaceae by the finding that it produces prieurianin, a complex limonoid characteristic of the subfamily Meliodeae. However, there has been no chemical evidence to link it more specifically to the tribe Turraeeae, in which it is placed. We now report that nymania-1, a characteristic limonoid of Nymania capensis, also occurs in the seed of Turraea obtusifolia. This evidence provides a chemotaxonomic link between the genera Nymania and Turraea. Die genus Nymania is oorspronklik chemotaksonomies met die familie Meliaceae verbind, omdat dit 'n komplekse limonoïed, prieurianin, vervaardig wat 'n kenmerk van die onderfamilie Meliodeae is. Maardaar is nog geen chemiese bewyse om Nymania meer spesifiek met die tribus Turraeeae te verbind nie. Ons berig hierin dat nymania-1, 'n karakteristieke limonoi’ed van Nymania capensis, ook in die saad van Turraea obtusifolia gevind is. Hierdie bewyse verskaf 'n chemotaksonomiese verbintenis tussen die genera Nymania en Turraea.
