Elemental composition and chemical characteristics of five edible nuts (almond, Brazil, pecan, macadamia and walnut) consumed in Southern Africa
The total elemental concentrations and proximate chemical composition of five different tree nuts, almond, Brazil, pecan, macadamia, Macadamia integrifolia and walnut that are consumed in South African households were investigated and useful in calculating the Dietary Reference Intakes of these nutrients.

Elemental distribution including toxic elements in edible and inedible wild growing mushrooms from South Africa
It is revealed that the accumulation of metals from the soil is independent of whether mushrooms are edible or inedible as uptake is dependent on the soil quality and its environment. Expand
Antibacterial and anti-adhesion activity of the pentacyclic triterpenoids isolated from the leaves and edible fruits of Carissa macrocarpa
Four pentacyclic oleanane triterpenes (β-amyrin, methyl oleanolate, oleanolic acid and 3β-hydroxyolean-11-en-28,13β-olide) were isolated from the fruits of Carissa macrocarpawhilst the ursaneExpand
Elemental composition of Cyrtanthus obliquus and Lippia javanica used in South African herbal tonic, Imbiza
Abstract Imbiza is a herbal tonic, which has gained popularity amongst South Africans as an immune booster and for the treatment of many minor and chronic illnesses. Main ingredients of Imbiza areExpand
Elemental composition and fatty acid profile of the edible fruits of Amatungula (Carissa macrocarpa) and impact of soil quality on chemical characteristics.
The Amatungula fruit showed tendency to accumulate Pb, with Pb levels in fruit at all sites being toxic to human health, indicating the impact of these metals on Pb availability. Expand
Fatty acid profile and elemental content of avocado (Persea americana Mill.) oil –effect of extraction methods
Oils from microwave extraction had the highest fatty acid content; oils from SFE had wider range of fatty acids; oil from Fuerte variety had a higher monounsaturated: saturated FA ratio. Expand
This study reveals that the plant is rich biologically active compounds thereby validating its ethno-medicinal use and demonstrated selective cytotoxicity towards cancer cells with high apoptosis indices in cells exposed to β-amyrin. Expand
Cytotoxicity, Antioxidant and Apoptosis Studies of Quercetin-3-O Glucoside and 4-(β-D-Glucopyranosyl-1→4-α-L-Rhamnopyranosyloxy)-Benzyl Isothiocyanate from Moringa oleifera.
Phytochemical analyses of the crude extracts of M.oleifera and biological activities of selected isolated compounds showed selective in vitro cytotoxic and apoptotic activity against human cancer and non-cancer cell lines, respectively. Expand
A dual-purpose silver nanoparticles biosynthesized using aqueous leaf extract of Detarium microcarpum: An under-utilized species.
The leaf extract of Detarium mirocarpum Guill & Perr, a small tree belonging to the family Fabaceae (Legume), was used to synthesize silver nanoparticles (DAgNPs), which were characterized using spectroscopic techniques which showed hydroxyl and carbonyl functional groups to be responsible for their synthesis.

Investigation of the Larvicidal Potential of Silver Nanoparticles against Culex quinquefasciatus
Biosynthesized silver nanoparticles AgNPs using Cassia hirsuta aqueous leaf extract were reported in this study. The synthesis was optimized by measuring various parameters such as temperature, time,Expand
