Objective. To To evaluate potential effects of the aqueous extract of Quassia amara L. leaves on the cardiovascular and respiratory systems of adult male Sprague- Dawley rats. Methods. The cardiovascular and respiratory effects of the Quassia amara L. leaf extract on adult male SpragueDawley rats were assessed using non-invasive blood pressure (NIBP) determination and head-out plethysmography, respectively, in a randomized, parallel group study. Mean observations of blood pressure and heart rate were recorded at different time periods after dosing. Respiratory flow and irritation effects were evaluated using mean observations of respiratory rate (RR), tidal volume (TV), mid-expiratory flow rate (EF50), time of inspiration (TI) and expiration (TE), and time of break (TB) and pause (TP). Results. There were no significant differences among the control and the treatment groups in SBP, DBP and HR parameters. The extract showed statistically significant effect on mean RR by time period (F=2.45, p=0.0234), trends over time of TV among the dose groups (F=2.00, p=0.0202), and EF50 among dose groups ((F=3.11, p=0.0422). However, these did not correlate with the changes in the time of break (TB) and time of pause (TP) which are more sensitive and specific tests for respiratory irritation. Conclusion. Aqueous leaf extract of Quassia appeared to have no significant effects on SBP, DPB, Pulse pressure, and HR. There are no conclusive dose-related respiratory flow or pulmonary irritation effects.

A busca por novos medicamentos à base de plantas para tratamento de doenças tem aumentado, sendo que 3/4 da população mundial utilizam remédios tradicionais tornando importante a realização de estudos sobre as alternativas terapêuticas através de abordagens etnobotânicas e quimiotaxonômicas. Foram obtidos dados e informações de 54 informantes, vendedores de plantas para uso medicinal, entrevistados individualmente nas feiras e mercados de São Luis, Maranhão, Brasil. Os dados foram analisados utilizando a frequência relativa (RF) e o fator de consenso informativo (ICF), e 30,3% das espécies selecionadas tiveram amostras coletadas e identificadas no Herbário do MAR, pertencendo a 20 famílias botânicas, sendo que 11,1% pertencem à família Asteraceae e 11,1% à família Fabaceae. As espécies mais citadas pelos informantes foram Hibiscus sabdariffa L., Baccharis crispa Spreng., Senna alexandrina Mill., Camellia sinensis (L.) Kuntze, Quassia amara L., Annona muricata L., Equisetum arvense L., com valores de RF > 5 e ICF > 0,50. A parte vegetal mais utilizada nos fitoterápicos para o tratamento da obesidade é a folha (74,1%), tendo a infusão (92,6%) como modo de preparo mais recomendado. Nossos resultados revelam uma lista de espécies indicadas pelos informantes para o tratamento da obesidade, algumas com estudos biológicos existentes, outras ausentes de estudos pré-clínicos e clínicos. As abordagens são importantes para a validação destas plantas através de estudos experimentais, considerando a necessidade de tais estudos para garantia da função biológica, eficácia e segurança das alternativas terapêuticas propostas.

Spray Treatment

In 2008 and 2009 the effects of quassin and neoquassin (oxygenated triterpenes) on apple sawfly (Hoplocampa testudinea Klug, 1814) were studied. In the Czech Republic, monitoring was carried out in small-plot trials and in one laboratory experiment. The extract containing quassin and neoquassin was made by boiling wood chips of a tropical shrub Quassia amara L. (Sapindales: Simaroubaceae). The experimental dosages were 3, 4.5, 6, and 9.25 kg of wood chips/ha. Spray treatment with the quassia extract was carried out just before most larvae hatched out. It was statistically proven that the extract from the wood of Q. amara reduced the apple sawfly infestation of fruitlets. Extract in the dosage corresponding to 3–4.5 kg of quassia wood chips for 1/ha appeared as optimal. The efficacy of these dosages was approximately 40–50%, and the efficacy above 80% was record.
