Resumo: | In Brazil, the cerrado is holding out for 20 to 50% of plant species in the country, contributing to research on natural products. Among the medicinal plants of the cerrado, Lafoensia pacari A. St.-Hil., known as dedaleiro or pacari is widely used as an antipyretic, healing, antiinflammatory, antidiarrheal, in gastritis and cancer. Studies have shown that extracts of L. pacari has antioxidant, anti-inflammatory, analgesic, antimicrobial and antidyspeptic activities. Among the groups of metabolites identified in L. pacari, stand out polyphenols, such as tannins and flavonoids, related to the its pharmacological activities. Due to the pharmacological importance of L. pacari, there is need for studies that may contribute to the standardization of plant parts as plant drug. Studies on the influence of environmental factors on production of the major groups of secondary metabolites of pacari are important because they contribute data to the cultivation and harvest, and to establish quantitative parameters of the plant drug metabolites. This study aimed to evaluate the influence of environmental factors like temperature, precipitation, mineral nutrients from soil and plant tissues on the concentration of secondary compounds in the leaves and bark of pacari. By spectrophotometric methods were determined levels of total phenols, tannins by protein precipitation, hydrolysable tannins, total flavonoids and ellagic acid in leaves and stem bark of L. pacari, as well as levels of nutrients in these tissues during the period of one year in five localities, with collections quarterly. Analysis was performed for the soil fertility of each collection site was the second standard procedure by EMBRAPA. The data were analyzed using Canonical Redundancy Analysis and Hierarchical Cluster Analysis. The results, after statistical analysis, showed that the leaves of L. pacari there is a influence of seasonality, with the temperature and leaf micronutrients (Cu, Fe, Mn, Zn) being the main factors of influence by environment and for the stem bark of L. pacari the location (region) where the specimen is collected is the main factor of variation in phenolic compounds, with soil fertility exerting greater influence on the stem bark. This study showed that for L. pacari climatic factors, nutritional status of plant tissue and soil conditions, exert influence on the phenolic compounds found in plant tissues analyzed from this plant. |

Dentre as plantas medicinais do cerrado, Lafoensia pacari A. St.-Hil., conhecida como dedaleiro ou pacari, é amplamente utilizada como antipirético, cicatrizante, anti-inflamatório, antidiarréico, no tratamento de gastrite e câncer. Estudos indicam que extratos de L. pacari apresentam atividade antioxidante, antiinflamatória, analgésica, antimicrobiana e antidispéptica. Dentre os grupos de metabólitos identificados em folhas e casca do caule de L. pacari, destacam-se os polifenóis, como taninos e flavonóides, relacionados às suas atividades farmacológicas. Devido à importância farmacológica de L. pacari, há necessidade de estudos que possam contribuir para a padronização das partes da planta como matéria-prima vegetal. Estudos acerca da influência de fatores ambientais sobre a produção dos principais grupos de metabólitos secundários do pacari são importantes, pois contribuem com dados para o cultivo e coleta, e para estabelecer parâmetros quantitativos dos metabólitos da droga vegetal. Este trabalho teve como objetivo avaliar a influência de fatores ambientais como temperatura, precipitação, nutrientes minerais do solo e dos tecidos vegetais, sobre concentração dos principais metabólitos secundários das folhas e da casca do caule do pacari. Através de métodos espectrofotométricos foram determinados os teores de fenóis totais, taninos por precipitação de proteínas, taninos hidrolisáveis, flavonóides totais e ácido elágico nas folhas e casca do caule de L. pacari, assim como os níveis de nutrientes minerais nestes tecidos durante o período de um ano em cinco localidades, com coletas trimestrais. Foi realizada a análise de fertilidade para os solos de cada localidade de coleta segundo procedimento padronizado pela EMBRAPA. Os dados obtidos foram analisados através de Análise de Redundância Canônica e Análise de Agrupamento Hierárquico. Os resultados obtidos, após a análise estatística, demonstraram que para as folhas de L. pacari existe influência da sazonalidade, com a temperatura e os micronutrientes foliares (Cu, Fe, Mn, Zn) sendo os principais fatores de influência do ambiente e que para a casca do caule de L. pacari o local (região) em que o espécime se encontra é o principal fator de variação nos teores de compostos fenólicos, com a fertilidade do solo exercendo maior influência sobre a casca do caule. Este estudo sugere que para L. pacari, fatores climáticos, estado nutricional do tecido vegetal e às condições de solo exercem influência sobre os teores de compostos fenólicos encontrados nos tecidos vegetais analisados desta planta.Made available in DSpace on 2014-07-29T16:11:47Z (GMT).
