TL;DR: It is stressed that the cantharophilous syndrome, as it is found in the Annonaceae, Magnoliaceae, Eupomatiaceae andCalycanthaceae, with beetles being exclusive pollinators, is a secondary and derived condition and obviously different from the expected basic entomophily of the original angiosperms.
Abstract: Dynastid scarab beetle pollination appears basic within the genusAnnona. Those species ofAnnona which are more morphologically derived, as well as allRollinia spp. possess reduced floral chambers and attract small beetles likeNitidulidae orStaphylinidae. Pollination of the primitive species ofAnnona byDynastinae would imply that the genus had not evolved before the Tertiary. The fossil record is in congruence with this hypothesis. Once again it is stressed that the cantharophilous syndrome, as it is found in theAnnonaceae, Magnoliaceae, Eupomatiaceae andCalycanthaceae, with beetles being exclusive pollinators, is a secondary and derived condition and obviously different from the expected basic entomophily of the original angiosperms.

TL;DR: Recent molecular studies in the genus Annona revealed the very close relationship of these genera and no satisfactory possibility was found to split up Annona for maintaining Rollinia as a distinct genus.
Abstract: Recent molecular studies in the genus Annona, which included two species of Rollinia and one, formerly placed in Raimondia, revealed the very close relationship of these genera. If Rollinia would be kept as a separate entity, Annona would become polyphyletic. No satisfactory possibility was found to split up Annona for maintaining Rollinia as a distinct genus. On the basis of these findings the necessary nomenclatural changes are presented here.

TL;DR: Romucosine (1) as discussed by the authors is a novel aporphinoid alkaloid possessing a N-(methoxycarbonyl) group, along with 12 known compounds including eight isoquinoline alkaloids, anonaine (2), glaucine, purpureine, liriodenine, oxoglaucine and oxopurpureine.
Abstract: Romucosine (1), a novel aporphinoid alkaloid possessing a N-(methoxycarbonyl) group, along with 12 known compounds including eight isoquinoline alkaloids, anonaine (2), glaucine, purpureine, liriodenine, oxoglaucine, oxopurpureine, berberine, and tetrahydroberberine, and four lignans, yangambin, magnolin, eudesmin, and membrin, have been isolated and characterized from the fresh unripe fruits of Rollinia mucosa (Annonaceae). The structure of 1 was established by chemical and spectroscopic means.

TL;DR: Alkaloids 1 and 4 exhibited significant inhibition of collagen, arachidonic acid, and platelet activating factor-induced platelet aggregation, and alkaloid 3 also showed an inhibitory effect on arachidsonic acid induced platelets aggregation.
