Resumo
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 e as possíveis interacções com os fármacos para que pudessem ser
empregues de forma segura no complemento de terapias convencionais.
Muitos metabolitos secundários [flavonóides] derivados de plantas são conhecidos por
possuírem importantes actividades farmacológicas ao actuarem sobre o sistema
biológico como antioxidantes e anti-inflamatórios.
Os flavonóides estão amplamente distribuídos nas plantas como produto do seu
metabolismo. Entre as diversas actividades biológicas atribuídas a estes metabolitos
destacam-se as actividades antioxidantes e anti-inflamatórias, abordadas nesta
monografia.
Este trabalho pretende rever os extractos naturais, que contenham flavonóides com
acção antioxidante e anti-inflamatória em patologias cardiovasculares e geniturinárias.
Estas populações foram escolhidas pelo facto das doenças cardiovasculares serem a
principal causa de morte na União Europeia, e devido à importância das doenças do
trato geniturinário terem aumentado muito na medicina clínica, pois essa é uma área
essencial para a compreensão de muitas doenças. Torna-se importante o enfoque de
algumas dessas doenças através do presente trabalho, numa tentativa de ampliar o
conhecimento sobre o assunto.
Embora existam muitos estudos nesta área apenas serão consultados estudos que
refiram um efeito bem documentado da acção terapêutica dos flavonóides.
Plants were the first source used by people for phytotherapy purposes. The word phytotherapy come from the greek therapeia (treatment) and phyton (vegetable). It mostly consists of the study of medicinal plants and the way its used to treatment of several diseases. Along the years the use of plants as therapeutically agents significantly contributed to the development of new pharmaceutical substances. For this reason, it became crucial to know its active components and underlying action mechanisms, secondary effects and potential interactions with other pharmaceutical substances in order to be used in a safe and effective manner for conventional therapies. Several secondary metabolites [flavonoids] derived from plants usually known to have relevant pharmaceutical impacts acting as anti oxidants and anti inflammatory on the biological system. The flavonoids are basically plant metabolites. Within many of its beneficial effects, the most relevant are anti oxidant and anti inflammatory as mentioned in this study. This paper aims to review the natural extracts containing flavonoids with antioxidant activity and anti-inflammatory genitourinary and cardiovascular action on pathologies. These populations were chosen because cardiovascular diseases are the leading cause of death in the European Union, and because of the importance of diseases of the genitourinary tract nowadays in clinical medicine, since this is a key area for understanding many diseases. It is important the focus of some of these diseases through the present work, an attempt to expand knowledge on the subject. Although there are many studies in this area only well documented studies of the therapeutic action of flavonoids will be dicussed in this monography.
