Annoglabrin A-C, three new ent-kaurane diterpenoids from the fruit pulp.

Three new -kaurane diterpenoids, namely annoglabrin A-C (), were isolated from the fruit pulp. Their structures were clarified by widespread spectroscopic analyses (1D and 2D NMR, HRESIMS). The relative configuration of these new compounds was established through the NOESY spectrum.
