Piptaderol from Piptadenia africana.
A new glyceryl derivative (Glyceryl-1-hexacosanoate) and a flavone derivative (methyletherapigenin) were isolated from the stem bark extract of Piptadenia africana, a western Cameroonian plant species. Common terpenes like sitosterol, beta-amyrin and eicosane were also isolated. These compounds were identified using physical and spectroscopic methods including mp, IR, (1)H and (13)C-NMR, DEPT, ...
متن کاملLoxodonta africana – African Elephant
Taxonomic notes: Preliminary genetic evidence suggests that there may be at least two species of African Elephant, namely the Savannah Elephant (Loxodonta africana) and the Forest Elephant (Loxodonta cyclotis) (Roca et al. 2001, 2005). A third species, the West African Elephant, has also been postulated. The IUCN SSC African Elephant Specialist Group currently accepts the single species proposa...
متن کاملEstimating exposed pulp lengths of tusks in the African elephant (Loxodonta africana africana).
Captive and wild African elephants frequently suffer tusk fractures. Several institutions shorten the tusks of captive elephants to reduce fractures and injury as a result of behaviour within enclosures. Fracturing or coronal amputations that expose pulp lead to pain for the elephant. Estimating coronal pulp lengths may thus help to minimise the risk of pulp exposure during amputations. We aime...
متن کاملA Novel Objective Method of Estimating the Age of Mandibles from African Elephants (Loxodonta africana Africana)
The importance of assigning an accurate estimate of age and sex to elephant carcasses found in the wild has increased in recent years with the escalation in levels of poaching throughout Africa. Irregularities identified in current ageing techniques prompted the development of a new method to describe molar progression throughout life. Elephant mandibles (n = 323) were studied and a point near ...
متن کاملAntidiarrhoeal and Antiulcer Activities of Mammea Africana
The stembark of Mammea africana is used traditionally for the treatment of stomach pains. The present study was designed to evaluate the effects of ethanolic stembark extract of Mammea africana on experimentally induced diarrhoea and ulcer . The extract ( 30 – 90mg/kg) was administered orally in rats 30 minutes to one hour before the induction of diarrhoeal and ulcer using di...
