This thesis describes phytochemical and biological/pharmacological studies on six medicinal plants. Plant materials were extracted by ethanol, tested for their biological activity and then subjected to "bioassay-guided fractionation" to yield active and inactive compounds. The compounds were identified by standard physico-chemical techniques including UV, IR, NMR and ElMS. The crude ethanol extract of the leaves of Premna shcimperi was found to be antibacterial against gram positive bacteria (Staphylococcus aureus and Bacillus subtilis).

Abstract:
Orientação : Amílcar Roberto<br>A malária é a doença parasitária mais preocupante da atualidade, sendo um grave problema de saúde pública, principalmente em África onde mata maioritariamente crianças com idade inferior a 5 anos. As estratégias farmacoterapêuticas de combate à malária, baseiam-se principalmente nos fármacos derivados da artemisinina e em fármacos quinolínicos. A artemisinina e a quinina são fármacos provenientes das espécies vegetais, Artemisia annua L. e Cinchona L., respectivamente, e são conhecidos há muito tempo pela medicina tradicional. Estas substâncias são as qu

Abstract:
La prévalence de l’obésité, du diabète de type 2, et du syndrome métabolique, sont à la hausse chez les Cris d’Eeyou Istchee (CEI-Nord du Québec). Ces problèmes sont aggravés par leur diète non traditionnelle, leur sédentarité, ainsi que par une résistance culturelle aux produits pharmaceutiques. Afin de développer des traitements antidiabétiques culturellement adaptés, notre équipe a effectué une enquête ethnobotanique qui a identifié 17 plantes provenant de la pharmacopée traditionnelle des CEI. À partir des études de criblage effectuées in vitro, deux plantes parmi les 17 ont attiré notre a

Orientação : Maria de Fátima Frazão<br>As plantas foram os primeiros recursos utilizados pelos povos como parte integral da fitoterapia. A fitoterapia, etimologicamente deriva dos termos gregos therapeia (tratamento) e phyton (vegetal). Significa o estudo de plantas consideradas medicinais e da sua aplicação no tratamento de doenças. Com o passar dos anos o uso das plantas como agentes terapêuticos, contribuiu muito para o desenvolvimento de novos fármacos pelo que, tornou-se imprescindível conhecer os seus princípios activos, os mecanismos de acção subjacentes, os efeitos secundários

South Africa is home to a wide diversity of cultural groups, all of which utilize the flora for a variety of purposes. This is true with regard to traditional medicine systems which are similar to those of the rest of Africa south of the Sahara, with diviners (sangomas) and herbalists (inyangas) as the key health providers. In addition, the Country is rich in plant diversity with some 30 000 species of flowering plants - almost one tenth of the worlds recorded higher plants. This incorporates a large diversity of plants including trees, shrubs, herbs, bulbs and corms. The adverse effects of tr

De facto, uma fracção significativa das populações dos países em desenvolvimento permanece dependente dos conhecimentos ancestrais sobre plantas para os seus cuidados de saúde. Ainda assim, continua a existir uma lacuna entre os progressos observados na farmácia clínica e os no campo da fitoterapia e da medicina tradicional, continuando muitos produtos naturais com actividade biológica por identificar.
