background: garcinia kola seed is consumed indiscriminately in nigeria without recourse to its potential toxicity. therefore, this study was aimed at assessing the toxicity of the aqueous extract of g. kola seeds on selected tissues of male rats.  methods: thirty male rats (215.00 ± 18.58 g) were assigned into four groups: a, b, c and d which received 0.5 ml of distilled water, 25, 50 and 100 m...

The present study was carried out to investigate laboratory germination responses of six collections of Garcinia kola seeds to six different hormonal pre-germination treatments. This consisted of soaking seeds for three days in cool distilled water (control), in cool distilled water supplemented with 10 M of either naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D), benzylamin...

The antispasmodic and spasmolytic effects of methanolic extract of seeds of Garcinia kola Heckel were studied on smooth muscle preparations in vitro. The influence of the extract on rat duodenum, jejunum and ileum was investigated using acetylcholine and barium chloride as agonists. The extract exhibited dose-dependent antispasmodic effects on contractions induced by acetylcholine, and dose-dep...

The in vitro antibacterial activity of crude methanolic extract of the seeds of Garcinia kola was investigated. The extracts exhibited antibacterial activities with zones of inhibition ranging from 10 mm to 25 mm. The minimum inhibitory concentration of the diethyl ether fraction was between 0.313 and 5.0 mg/ml, while that of butanol fraction varied from 0.157 to 5.0 mg/ml. The butanol fraction...

Garcinia has some 260 species and is often regarded as a genus with a difficult taxonomy. No recent treatment is available for the botanically rich Lower Guinea phytogeographical region. This study aims at partly filling this gap. First, several taxonomic problems are solved. Garcinia chromocarpa is reduced to a variety of Garcinia quadrifaria. Garcinia gnetoides and Garcinia granulata are both...

The biological activities of water extract from Garcinia kola (G. kola) were investigated in growing Wistar rats. Three doses of G. kola extract (0, 10, 20 mg G. kola/100g body mass of rat) were administered daily by gavage to the respective groups of 15 rats for a period of 70 days. The animals were offered standard rat diet and water ad libitum. The plant extract had a depressive effect (P<0....

Background: Garcinia kola is used in traditional medicine in various parts of Africa including Nigeria for the amelioration of hypertension, cough, diabetes, sickle cell anemia, bacterial and fungal infections amongst others. The prophylactic and therapeutic efficacy of Garcinia kola biflavonoid fractions (GKBF); root bark (RBBF), stem bark (SBBF) and seed (SBF)) on the lipid profile and kidney...

Garcinia lanceifolia Roxb. is an important and endemic medicinal plant of Assam which has been used by various ethnic communities of Northeast India to treat various disorders like dysentery, dyspepsia, and biliousness. The plant is considered to be containing much medicinal value and is also eaten raw or made into pickles by the local people. Our present study has been focused on the evaluatio...

southern part of Nigeria and other west African nations. Examinations of the liver, kidney and duodenum of rats fed a diet containing 10% w/w of dry powdered seed of the kola for 6 weeks has been reported as revealing some useful histological alterations in these organs. In some Nigerian houses it is served as a substitute for the true kola nuts (Cola nitida and Cola acuminata). It has a bitter...

The present work was designed to assess the antibacterial properties of the methanol extracts of some Cameroonian medicinal plants and the effect of their associations with currently used antibiotics on multidrug resistant (MDR) Gram-negative bacteria overexpressing active efflux pumps. The antibacterial activities of twelve methanol extracts of medicinal plants were evaluated using broth micro...
