Article
Full-text available
Human micronutrient dietary deficiency remains an enormous global problem and probably accounts for the cause of many chronic health conditions and diseases. Above two (2) billion individuals on the planet today have been estimated to be deficient in major minerals and vitamins, predominantly zinc, iodine, vitamin A, and iron primarily due to inade...

The variabilities in the phytochemical contents and antioxidant activities of four varieties of two closely related cultivated Capsicum species, C. annuum and C. frutescens , were examined as an additional tool for establishing their phylogenetic relatedness and for breeding purposes. The methodology involved the use of ethanolic and aqueous extrac...
Article
Ethnopharmacological relevance Sceletium tortuosum (L.) N.E.Br, the most sought after and widely researched species in the genus Sceletium is a succulent forb endemic to South Africa. Traditionally, this medicinal plant is mainly masticated or smoked and used for the relief of toothache, abdominal pain, and as a mood-elevator, analgesic, hypnotic,...
Article
Full-text available
The genus Merremia Dennst. ex Endl. (Convolvulaceae) is a rich source of structurally diverse phytochemicals with therapeutic relevance. This review presents the first comprehensive, up-to-date information and research progression on the nutritional value, ethnomedicinal uses, phyto-chemistry, pharmacological activities, and toxicity of the genus M...
Article
Full-text available
Evolvulus alsinoides (L.) L. (Convolvulaceae) is a forb species that is highly valued in traditional medicine for its memory-enhancing effects, and a range of other ethnomedicinal properties. However, there are no studies on the phytochemical composition and antioxidant activities of E. alsinoides collected in South Africa. The present study was de...
Article
Full-text available
Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is one of the most important natural products in the genus Capsicum. Due to its numerous biological effects, there has been extensive and increasing research interest in capsaicin, resulting in increased scientific publications in recent years. Therefore, an in-depth bibliometric analysis of published li...
Article

Mallotus oppositifolius (Geiseler) Müll. Arg. (Euphorbiaceae) is an important and multipurpose medicinal herb found in different African countries. Its various parts possess several pharmacological activities. However, to date, there is no literature review collating the traditional uses, phytochemistry and biological activities of M. oppositifoliu...
Article
The genus Aloe has attracted considerable research attention in the last two decades owing to its ethnomedicinal, nutraceutical, pharmaceutical, and cosmeceutical importance. This review aimed to evaluate the performance of research outputs, identify evolving trends and research hotspots, and present a detailed summary of recent research reports on...
Article
Full-text available
The maintenance of seed quality during the long-term conservation of plant genetic resources is crucial for averting the projected food crises that are linked to the changing climate and rising world population. However, ageing-induced loss of seed vigour and viability during storage remains an inevitable process that compromises productivity in se...

Ethnopharmacological relevance Sceletium tortuosum (L.) N.E.Br., the most sought after and widely researched species in the genus Sceletium is a succulent forb endemic to South Africa. Traditionally, this medicinal plant is mainly masticated or smoked and used for the relief of toothache, abdominal pain, as a mood-elevator, analgesic, hypnotic, anx...
Article
Overdependence on exotic plant species constitutes a major setback for the consumption of wild fruits and vegetables among South Africans. The country is not spared from the adverse effects of climate change which play a substantial role in altering the ecosystem and have a ripple effect on food security. Wild fruits and vegetables have been identi...

Globally, the prevalence of diabetes has risen significantly by 62% over the last ten years. A complication of unmanaged diabetes is diabetic foot ulcer (DFU), which adversely affects the quality of life of individuals with diabetes and inflicts a huge economic burden on the family, government, and health care services. However, this complication i...

Background Limonoids are a class of highly oxygenated modified triterpenoids with a diverse range of biological activities. Although with restricted occurrence in the plant kingdom, these compounds are found extensively in the Meliaceae and Rutaceae families. Limonoids are of great interest in science given that the small number of plant families w...
Article
Full-text available
The study evaluated the degree of relatedness and variability in foliar epidermal features of four varieties of two closely related cultivated Capsicum species, C. annuum L. and C. frutescens L., in West Africa using light microscopy, scanning electron microscope (SEM) and energy dispersive X-ray (EDX) spectroscopy. The varieties used in the study...
Article
Full-text available
Peppers (Capsicum spp.) contain several bioactive compounds with nutritional and pharmaceutical importance, and these differ between pepper types. The assessment of variation and relatedness among genotypes, varieties or accessions of plant species is important in breeding, conservation and management of genetic resources. Four varieties belonging...
Article
Full-text available
The taxonomic identity of two closely related Capsicum species; Capsicum annuum and Capsicum frutescens in West Africa has not been clarified because they have overlapping morphological traits. Effective control and management measures as well as improvement of crop plants in any breeding programme can only be implemented when plant species are cor...
Article
Full-text available
Seed germination, a phylogenetically conserved trait, is crucial for seedling establishment and survival in nature and can be used to establish phylogenetic relatedness among plant species. The current study evaluated seed germination characteristics of varieties of two closely related cultivated Capsicum species in West Africa in response to light...
Article
Full-text available
The study was aimed at assessing the genetic variation and relatedness among four Capsicum varieties through electrophoretic separation of their leaf and seed proteins by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Total seed and leaf proteins were extracted and separated on 12% polyacrylamide gels using standard proto...
Article
Full-text available
In West Africa, the genus Capsicum is represented by two cultivated species namely C. frutescens and C. annuum with different varieties. However, the taxonomic identity of these two species has been unresolved because they are morphologically related. There has been considerable debate on their status as two separate species or just varieties of on...
Article
Full-text available
The current study aimed to evaluate the pollen viability of the commonly cultivated varieties of Capsicum species and assessed the potentials for gene exchange among the genotypes through hybridization studies. Capsicum annuum var. abbreviatum, C. annuum var. acuminatum, C. annuum var. grossum and C. frutescens var. baccatum were the species and va...

In an attempt to evaluate the acclaimed aphrodisiac activity of ethanol leaf extract of Piliostigma thoningii, twenty (20) male wistar albino rats were weighed and grouped into four study groups (A-D) of five animals each. Rats in group A (control) were administered with 1ml of distilled water orally while those in groups B, C, and D were given sam...
