TL;DR: Five essential oils extracted from the Cameroonian plants were evaluated in regard to their anti-plasmodial activity against the W2 strain of Plasmodium falciparum, and the most effective was the oil of Hexalobus crispiflorus, with an IC50 of 2 microg/ml.

TL;DR: The antioxidant extracts from both A. melegueta and X. aethiopica inhibited the growth of Escherichia coli and Bacillus cereus and were tentatively identified as phenolic compounds with X.aethiopicas having a trihydroxyl phenolic component with reducing properties.
Abstract: Extracts of the spices, Aframomum melegueta (family, Zingiberaceae) and Xylopia aethiopica (family, Anonaceae) exhibited antioxidant effects on lard and groundnut oil with A. melegueta having an antioxidant effectiveness (AE) of 57.0% in lard and 54.3% in groundnut oil at 300 ppm.

The AE of X. aethiopica for lard at 300 ppm was 29.6%. The antioxidant extracts from both A. melegueta and X. aethiopica inhibited the growth of Escherichia coli and Bacillus cereus. The antioxidant extracts from X. aethiopica and A. melegueta were tentatively identified as phenolic compounds with X. aethiopica having a trihydroxyl phenolic component with reducing properties.

TL;DR: In this article, the essential oil of Xylopia aethiopica from dried fruit and the powder obtained from crushed dried fruit using combined GC and GC/MS was analyzed and the principal constituents identified in the fruit oil were β-pinene (19.1%), γ-terpinene(14.7%), trans-pinocarveol (8.6%) and p-cymene (7.3%).
Abstract: We analyzed the essential oil of Xylopia aethiopica from dried fruit and the powder obtained from crushed dried fruit using combined GC and GC/MS. The principal constituents identified in the fruit oil were β-pinene (19.1%), γ-terpinene (14.7%), trans-pinocarveol (8.6%) and p-cymene (7.3%). In the oil from the powder die major constituents were β-pinene (9.9%), α-cadinol (6.9%), trans-pinocarveol (4.6%), α-pinene (4.1%) and 1,8-cineole (4.0%).

TL;DR: The nonspecific mechanism of action makes X. aethiopica a safer spice which can be exploited in the management of exophoria and raised intraocular pressure (glaucoma) in instances where the efficacy of the older conventional drugs is insufficient.

TL;DR: Thirteen acetogenins, from the roots of Uvaria chamae and Annona senegalensis, were identified, which could partly explain the biological proprieties of these various drugs.
Abstract: Annonaceae is a large family of plants widely used in alimentation and traditional medicine. The interest of their study is raised up by the presence of biologically active substances among that the acetogenins which are specific to them. In Senegal, three species are widely used in traditional medicine for various indications and particularly in parasitic diseases: Annona senegalensis, Uvaria chamae and Xylopia aethiopica. The study of antiparasitical extracts from various organs showed an interesting activity of the fruits and leaves of Xylopia aethiopica on Leishmania donovani, the stem barks and roots of Uvaria chamae on Trypanosomia brucei and the roots of Annona senegalensis on the chloroquino-resistant strain of Plasmodium falciparum. Bioguided fractionation of the active extracts led to isolate Annonaceous acetogenins. Therefore, thirteen acetogenins, from the roots of Uvaria chamae and Annona senegalensis, were identified. The presence of acetogenins, substances with antiparasitical activity, could partly explain the biological proprieties of these various drugs.
