Resumo: Species of Polygala genus have been used for the treatment of inflamation and pain in Turkish traditional medicine. The aim of the present study is to assess the anti-inflammatory and analgesic activities of P. anatolica. n-Hexane, ethyl acetate and methanol extracts of the aerial parts and roots of P. anatolica were investigated for their anti-inflammatory and analgesic effects. The methanol extracts prepared from the aerial parts and roots of P. anatolica were found to be active in carrageenan- and PGE2-induced paw edema models and in Whittle method. Methanolic extract of the aerial part inhibited serotonin-induced hind paw edema, while the root extract did not exert inhibitory effect in the same model. In addition, Fr. B and C obtained from the methanol extract of P. anatolica aerial parts showed significant anti- inflammatory activity. Morover, the analgesic effect of the methanol extracts prepared from the roots and aerial parts and Fr.B and Fr.C were found to be statistically significant without inducing ulceration. The methanol extract obtained from the aerial parts of the plant and its saponoside and flavonoid fractions showed anti-inflammatory and analgesic activities in the trials.

Las especies del género Polygala se han utilizado para el tratamiento de la inflamación y el dolor en la medicina tradicional turca. El objetivo del presente estudio es evaluar las actividades antiinflamatorias y analgésicas de P. anatolica. Se investigaron los extractos de n-hexano, acetato de etilo y metanol de las partes aéreas y raíces de P. anatolica por sus efectos antiinflamatorios y analgésicos. Los extractos de metanol preparados a partir de las partes aéreas y raíces de P. anatolica se encontraron activos en modelos de edema de pata inducidos por carragenina y PGE2 por el método de Whittle. El extracto metanólico de la parte aérea inhibió el edema de la pata trasera inducido por serotonina, mientras que el extracto de raíz no ejerció un efecto inhibidor en el mismo modelo. En suma, la fracción B y C obtenidos a partir del extracto metanólico de partes aéreas de P. anatolica mostraron actividad antiinflamatoria significativa. Además, el efecto analgésico de los extractos de metanol preparados a partir de las raíces y las partes aéreas y la fracción B y C resultaron ser estadísticamente significativas sin inducir la ulceración. El extracto de metanol obtenido de las partes aéreas de la planta y sus fracciones de saponósidos y flavonoides mostraron actividades antiinflamatorias y analgésicas en los ensayos.

Título: Antifungal activity of five species of Polygala
Fonte: Braz. j. microbiol;42(3):1065-1075, July-Sept. 2011. ilus, tab.
Idioma: en.
Resumo: Crude extracts and fractions of five species of Polygala - P. campestris, P. cyparissias, P. paniculata, P. pulchella and P. sabulosa - were investigated for their in vitro antifungal activity against opportunistic Candida species, Cryptococcus gattii and Sporothrix schenckii with bioautographic and microdilution assays. In the bioautographic assays, the major extracts were active against the fungi tested. In the minimal concentration inhibitory (MIC) assay, the hexane extract of P. paniculata and EtOAc fraction of P. sabulosa showed the best antifungal activity, with MIC values of 60 and 30 µg/mL, respectively, against C. tropicalis, C. gattii and S. schenckii. The compounds isolated from P. sabulosa prenyloxycoumarin and 1,2,3,4,5,6-hexanehexol displayed antifungal activity against S. schenckii (with MICs of 125 µg/mL and 250 µg/mL, respectively) and C. gattii (both with MICs of 250 µg/mL). Rutin and aurapten isolated from P. paniculata showed antifungal activity against C. gattii with MIC values of 60 and 250 µg/mL, respectively. In the antifungal screening, few of the isolated compounds showed good antifungal inhibition. The compound á-spinasterol showed broad activity against the species tested, while rutin had the best activity with the lowest MIC values for the microorganisms tested. These two compounds may be chemically modified by the introduction of a substitute group that would alter several physico-chemical properties of the molecule, such as hydrophobicity, electronic density and steric strain.
