Plantas com possível atividade hipolipidêmica: uma revisão bibliográfica de livros editados no Brasil entre 1998 e 2008 Plants with possible hypolipidemic activity: a review of books published in Brazil between 1998 and 2008

O objetivo deste trabalho foi realizar levantamento sobre as plantas medicinais indicadas para o tratamento da hiperlipidemia, hipercolesterolemia e/ou aterosclerose. Este estudo foi feito a partir da pesquisa bibliográfica em 32 livros publicados no Brasil entre 1998 e 2008, resultando em lista de 85 espécies distribuídas em 53 famílias, principalmente Asteraceae e Fabaceae, com 54 espécies exóticas e 31 nativas. As espécies mais citadas foram Allium sativum (Alliaceae), Cynara scolymus (Asteraceae), Curcuma longa (Zingiberaceae), Allium cepa (Alliaceae), Echinodorus grandiflorus (Alismataceae), Taraxacum officinale (Asteraceae), Vernonia condensata (Asteraceae), Cuphea carthagenensis (Lythraceae) e Curcuma zedoaria (Zingiberaceae). As espécies nativas, citadas em pelo menos 2 livros, foram investigadas para alguma evidencia científica relacionada a possíveis efeitos hipolipidêmico, hipocolesterolêmico e/ou contra aterosclerose. Somente foram encontrados estudos científicos, relacionados a estes efeitos, para as espécies nativas Cuphea carthagenensis e Echinodorus grandiflorum, indicando a necessidade de pesquisas que possam garantir a segurança e a eficácia do uso destas espécies.<br>The aim of this study was to survey medicinal plants indicated for the treatment of hyperlipidemia, hypercholesterolemia and/or atherosclerosis.

Native species cited in at least 2 books were investigated for some scientific evidence related to possible hypolipidemic and hypocholesterolemic effects and/or action against atherosclerosis. Scientific studies related to these effects were found only for the native species Cuphea carthagenensis and Echinodorus grandiflorum, indicating the need for studies capable of assuring the safety and the efficacy as to the use of these species

Nutrients, Bioactive Compounds and Bioactivity: The Health Benefits of Sweet Cherries (Prunus avium L.)

Background: Sweet cherries are one of the most appreciated fruits worldwide as well as one of the great sources of several active substances, as phytochemical compounds (carotenoids, serotonin, melatonin and phenolic compounds) as well as in nutritive compounds (sugars and organic acids). Accumulating research demonstrate that their supplementation in our daily diet can contradict oxidative stress, mitigating or even attenuating chronic diseases, as cancerous processes, antiinflammatory- related disorders, diabetes, and neurological and cardiovascular pathologies. Therefore, the aims of this review are to present an overview on the effects of sweet cherries as health promotors, giving emphasis to the health benefits of their bioactive compounds, particularly their antimicrobial, antioxidant, antidiabetic, anticancer, anti-neurodegeneration, anti-inflammatory and cardiovascular effects. Methods: Research and online content about sweet cherry fruits is reviewed. The information available has been read several times to avoid inconsistencies. In addition, according what we read, original figures were done and added to facilitate understanding and to enrich the paper. Results: In this review, a total of 202 original reports were used. In respect to health benefits, it is possible to confirm by several studies that, in fact, the consumption of sweet cherries has positive impacts in human health, owing to their wealthy and vast constitution, particularly in phenolic compounds, vitamins and carotenoids whose health properties were already documented. Conclusion: The findings of this review support the evidence that sweet cherries can be applied in pharmaceutical and food formulations, since they are able to diminish free radical species and proinflammatory markers, preventing and/ or ameliorating oxidative-stress disorders
