TL;DR: The XA methanolic extract demonstrated a high content of phenolic compounds and significant antioxidative properties, with prospective potency to prevent oxidative damage and promote better cardiovascular health.
Abstract: Spices and herbs have antioxidant, anti-inflammatory, and anti-microbial properties, amongst others. These characteristics are attributable to their composition, such as high polyphenol and flavonoid contents that are responsible for their antioxidative properties. Methanolic extracts of Ocimum basilicum (OB), Xylopia aethiopica (XA), and Piper guineensis (PG) were evaluated to profile their phenolic compounds and in vitro antioxidant properties. High performance liquid chromatography with diode-array detection phenolic compounds profiling revealed that quercetin, quercitrin, and isoquercitrin are the most prevalent phenolic compound in OB, XA, and PG, respectively. All the extracts possessed good antioxidant activity. XA showed the highest total phenolic content of 29.50 mg gallic acid equivalents/g, a total flavonoid content of 21.17 mg quercetin equivalents/g, 2,2-diphenyl-1-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging abilities of 29% and 88.23%, respectively, and a nitric oxide scavenging activity of 44.13 mg/g. Thus, the XA methanolic extract demonstrated a high content of phenolic compounds and significant antioxidative properties, with prospective potency to prevent oxidative damage and promote better cardiovascular health.

TL;DR: The chemical composition of 48 essential‐oil samples isolated from the leaves of Xylopia aethiopica harvested in six Ivoirian forests was investigated by GC‐FID and 13C‐NMR analyses and allowed the distinction of two groups on the basis of the β‐pinene and germacrene D contents.
Abstract: The chemical composition of 48 essential-oil samples isolated from the leaves of Xylopia aethiopica harvested in six Ivoirian forests was investigated by GC-FID and (13) C-NMR analyses. In total, 23 components accounting for 82.5-96.1% of the oil composition were identified. The composition was dominated by the monoterpene hydrocarbons β-pinene (up to 61.1%) and α-pinene (up to 18.6%) and the sesquiterpene hydrocarbon germacrene D (up to 28.7%). Hierarchical cluster and principal component analyses allowed the distinction of two groups on the basis of the β-pinene and germacrene D contents. The chemical composition of the oils of Group I (38 oil samples) was clearly dominated by β-pinene, while those of Group II (10 samples) were characterized by the association of β-pinene and germacrene D. The leaves collected in the four inland forests produced β-pinene-rich oils (Group I), while the oil samples belonging to Group II were isolated from leaves harvested in forests located near the littoral.

TL;DR: The ethanolic extracts of the stem bark and root of Xylopia aethiopica showed the presence of alkaloids, saponins, flavonoids, tannins, terpenes, steroids and cardiac glycosides and both samples tested negative for anthraquinones.
Abstract: The ethanolic extracts of the stem bark and root of Xylopia aethiopica were used for the study. Preliminary phytochemicals present were quantified using standard procedures. The result of the screening of the two samples showed the presence of alkaloids, saponins, flavonoids, tannins, terpenes, steroids and cardiac glycosides and both samples tested negative for anthraquinones. The result indicates that alkaloids and cardiac glycosides in the root were significantly (p 0.05) difference were observed between the flavonoid content of the samples. The plant parts investigated in this work should be seen as a potential source of useful drugs.

TL;DR: This study provides a list of popular medicinal plants found in southern Benin (West Africa) with their mode of use, diseases treated, and thin-layer and high-performance liquid chromatography profiles.
Abstract: This study provides a list of popular medicinal plants found in southern Benin (West Africa) with their mode of use, diseases treated, and thin-layer and high-performance liquid chromatography profiles. The list includes 10 of the most widely used plant species from Dantokpa Market (biggest market located in Cotonou) and Abomey-Calavi in the Republic of Benin. Species were identified by the Laboratory of Botany and Applied Ecology, University of Abomey-Calavi. Voucher specimens were deposited in the herbarium of the Experimental Station for Medicinal Plants, Graduate School of Pharmaceutical Sciences, Kyoto University, Japan, and in the National Herbarium of Benin, University of Abomey-Calavi. The list was as follows-Azadirachta indica (Meliaceae), Caesalpinia bonduc (Caesalpiniaceae), Catharanthus roseus (Apocynaceae), Garcinia kola (Clusiaceae), Khaya senegalensis (Meliaceae), Monodora myristica (Annonaceae), Moringa oleifera (Moringaceae), Talinum fruticosum (Talinaceae), Tridax procumbens (Asteraceae), and Xylopia aethiopica (Annonaceae).
