Four known compounds, 5-Hydroxyflavone (1), 2’-Hydroxyflavanone (2), Paeonol (3) and bergenin (4), were isolated from the methanolic extract of the stem bark of Garcinia malaccensis for the first time through combination of vacuum and radial chromatography techniques. The structures of the secondary metabolites (1-4) were elucidated on the basis of their spectroscopic evidence and comparison wi...

We assessed the anti-Listerial activities of crude n-hexane and aqueous extracts of Garcinia kola seeds against a panel of 42 Listeria isolates previously isolated from wastewater effluents in the Eastern Cape Province of South Africa and belonging to Listeria monocytogenes, Listeria grayi and Listeria ivanovii species. The n-hexane fraction was active against 45% of the test bacteria with zone...

BACKGROUND The continuous emergence of multidrug-resistant (MDR) bacteria drastically reduced the efficacy of our antibiotic armory and consequently, increased the frequency of therapeutic failure. The search for bioactive constituents from endophytic fungi against MDR bacteria became a necessity for alternative and promising strategies, and for the development of novel therapeutic solutions. W...

The purpose of this study is to define the structural characteristics and spatial distribution endangered Garcinia kola in Côte d'Ivoire, order ensure sustainable management species. was conducted two natural growth zones (Affery Biankouma) species involved 94 trees with a minimum diameter 10 cm measured at 1.30 m from ground. data collection method consisted mobile inventory within 1...

Humanity has been hit in recent times, by unusual mortality provoked the emergence of COVID-19. A report 21 March 2020 Nigeria Centre for Disease Control (NCDC) confirmed 22 cases dreaded virus country. Desperate times they say require desperate measures. Facing pandemic, leadership more political than practical. Citizens resort to divers’ self-medication thus: Bathing with well-boiled Dogo Yar...

Experiments were conducted to study the effectiveness of powders of some underutilized botanicals for the control of Sitophilus zeamais. The tested plants are: Piptadeniastrum africanum, Piper guineense, Alstonia boonei, Garcinia kola, Xylopia aethiopica, Picralima nitida and Aristolochia repens. The effects of the powders were observed at different dosage rates : 0.0g (Control), 0.5g, 1.0g, 1....

Ghana, is chewed together with the kola nut by the local people before each meal to promote digestion, and is therefore called the false kola nut. It is believed to improve the flavor of anything eaten after it and even to render putrid water palatable. The beneficial effects of chewing this nut are generally thought to include the mechanical cleansing effect and anti-microbial substances in th...

A rapid capillary electrophoresis (CE) method for the quantification of four biologically active biflavanones present in three different traditional African medicinal preparations from the seeds of Garcinia kola was developed. The four biflavanones of interest (GB1, GB2 and GB1-glycoside and kolaflavanone) were quantified in a traditional tea preparation, and two commercially available ethanoli...
