Strychnos Spinosa
''Strychnos spinosa'', the Natal orange, is a tree indigenous to tropical and subtropical Africa. It produces sweet-sour, yellow fruits, containing numerous hard brown seeds. Greenish-white flowers grow in dense heads at the ends of branches (Sep-Feb/Spring - summer). The fruits tend to appear only after good rains. It is related to the deadly ''Strychnos nux-vomica'', which contains strychnine. The smooth, hard fruit are large and green, ripen to yellow colour. Inside the fruit are tightly packed seeds, which may be toxic, surrounded by a fleshy, brown, edible covering. Animals such as baboon, monkeys, bushpig, nyala and eland eat the fruit. The leaves are a popular food source for browsers such as duiker, kudu, impala, steenbok, nyala and elephant. Distribution This tree can be found growing singly in well-drained soils. It is found in bushveld, riverine fringes, sand forest and coastal bush from the Eastern Cape to Kwazulu-Natal, northwards to Mozambique, and inland to Eswatin ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eswatini
Eswatini ( ; ss, eSwatini ), officially the Kingdom of Eswatini and formerly named Swaziland ( ; officially renamed in 2018), is a landlocked country in Southern Africa. It is bordered by Mozambique to its northeast and South Africa to its north, west, south, and southeast. At no more than north to south and east to west, Eswatini is one of the smallest countries in Africa; despite this, its climate and topography are diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is composed primarily of ethnic Swazis. The prevalent language is Swazi (''siSwati'' in native form). The Swazis established their kingdom in the mid-18th century under the leadership of Ngwane III. The country and the Swazi take their names from Mswati II, the 19th-century king under whose rule the country was expanded and unified; its boundaries were drawn up in 1881 in the midst of the Scramble for Africa. After the Second Boer War, the kingdom, under the name of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strychnos
''Strychnos'' is a genus of flowering plants, belonging to the family Loganiaceae (sometimes Strychnaceae). The genus includes about 100 accepted species of trees and lianas, and more than 200 that are as yet unresolved. The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare. Etymology The name ''strychnos'' was applied by Pliny the Elder in his '' Natural History'' to ''Solanum nigrum''. The word is derived from the Ancient Greek στρύχνον (''strúkhnon'') – "acrid", "bitter". The meaning of the word ''strychnos'' was not fixed in Ancient Greece, where it could designate a variety of different plants having in common the property of toxicity. Distribution The genus has a pantropical distribution. Taxonomy The genus is divided into 12 sections, though it is conceded that ...

Fruits Originating In Africa
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarracenin
Sarracenin is an iridoid found in several plant species in the carnivorous family Sarraceniaceae. It also occurs in other non-carnivorous plants such as ''Strychnos spinosa'' (Loganiaceae) and ''Patrinia heterophylla'' (Caprifoliaceae). History Sarracenin was first isolated from the roots of ''Sarracenia flava'' in 1976. Analysis of ''S. flava'' extracts was prompted by their use as a folk remedy by people of the Okefenokee swamp region Biosynthesis Sarracenin is believed to be derived from loganin, with either morronoside or secologanin serving as intermediates in the biosynthetic process. Uses Sarracenin displays antimicrobial activity against several pathogens including ''Staphylococcus aureus'', ''Streptococcus pyogenes'', ''Shigella dysenteriae'', '' Klebsiella pneumonia'', ''Candida albicans,'' ''Candida tropicalis'', '' Candida thrusei'', and ''Candida stellatoidea''. It has also demonstrated cytotoxicity against three tumor cell lines: A375 (human melanoma cell), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iridoid
Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. Iridoids are typically found in plants as glycosides, most often bound to glucose. The chemical structure is exemplified by iridomyrmecin, a defensive chemical produced by the ant genus ''Iridomyrmex'', for which iridoids are named. Structurally, they are bicyclic ''cis''-fused cyclopentane-pyrans. Cleavage of a bond in the cyclopentane ring gives rise to a subclass known as ''secoiridoids'', such as oleuropein and amarogentin. Occurrence The iridoids produced by plants act primarily as a defense against herbivores or against infection by microorganisms. The variable checkerspot butterfly also contains iridoids obtained through its diet which act as a defense against avian predators. To humans and other mammals, iridoids are often characterized by a deterrent bitter taste. Aucubin and catal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiv People
Tiv (or Tiiv) are a Tivoid ethnic group. They constitute approximately 2.4% of Nigeria's total population, and number over 5 million individuals throughout Nigeria and Cameroon. The Tiv language is spoken by about 5 million people in Nigeria with a few speakers in Cameroon. Most of the language's Nigerian speakers are found in Benue, Taraba, Nasarawa, Plateau, Cross rivers, Adamawa, Kaduna, and Abuja States. The language is a branch of Benue–Congo and ultimately of the Niger–Congo phylum. In pre-colonial times, the Fulani ethnic group referred to the Tiv as "Munchi" (also sometimes written Munshi e.g. Duggan 1932 and Ako 1981), a term not accepted by Tiv people. They depend on agricultural produce for commerce and life. History The Tiv believe they emerged into their present location from the southeast. It is claimed that the Tiv wandered through southern, south-central and west-central Africa before arriving at the savannah lands of West African Sudan via the ...
