TLDR
In this paper, nine limonoids were isolated from Carapa guianensis and Cedrela fissilis and were assayed on Atta sexdens rubropilosa workers showing moderate insecticidal activities.Abstract:
Nine limonoids were isolated from Carapa guianensis and Cedrela fissilis Among them, 1,2-dihydro-3b-hydroxy-7-deacetoxy-7-oxogedunin is a new compound Moreover, the assignments of some chemical shifts of xyloccensin k have been corrected and 1H NMR data of 7-deacetylgedunin have been assigned for the first time These isolated limonoids were assayed on Atta sexdens rubropilosa workers showing moderate insecticidal activitiesread more

TL;DR: Findings indicate, for the first time, that oils of andiroba and aroeira (in their conventional and nanoemulsion forms) have high activity against T. evansi in vitro, leading to the suggestion that these oils may be applied as an alternative treatment for this disease.

Isolation of Limonoids from seeds of Carapa guianensis Aublet (Meliaceae) by high‐speed countercurrent chromatography
TL;DR: The use of gradient mode in HSCCC was a good alternative, exploiting small variations of partition coefficient between the substances, and it was possible to isolate limonoids in a good relative abundance, compared with classical chromatographic methods.
