1. Phenylacylated-flavonoids from Peucedanum chryseum
ABSTRACT Phytochemical investigation of the methanol extract of the aerial parts of Peucedanum chryseum (Boiss. & Heldr.) D.F.Chamb., Apiaceae, led to the isolation of a dihydrofuranochromone, cimifugin (1); a phloroacetophenone glucoside, myrciaphenone A (2); and a flavonoid glycoside, afzelin (3) along with two phenylacylated-flavonoid glycosides: rugosafl

2. PHENOLIC DERIVATIVES AND ANTIOXIDANT ACTIVITY OF POLAR EXTRACTS FROM Bauhinia pulchella
A tea made with the leaves or stem bark of Bauhinia pulchella Benth (Fabaceae) is used in the treatment of diabetes. Ethanol (EEF) and aqueous (EAF) extracts were obtained from the leaves and the antioxidant and citotoxic activities were tested, as well as quantify the content of flavonoids and phenolic compounds (TPC). EEF and EAF showed similar profiles by

3. Antinociceptive and anti-inflammatory activities of an aqueous extract of Chiliotrichum diffusum
The flowers of the Chiliotrichum diffusum (G. Forst.) Kuntze, Asteraceae, have long been used in traditional medicine and rituals. In this study, the anti-inflammatory and antinociceptive activities of a decoction of the flowers were evaluated and a phytochemical analysis was performed by HPLC-DAD. In order to evaluate the antinociceptive activity, the aceti

4. Dynamic maceration of Copaifera langsdorffii leaves: a technological study using fractional factorial design
The Copaifera langsdorffii Desf., Fabaceae, is a Brazilian native tree, known as copaiba, which oil is commonly used in folk medicine as muscle relaxant, wound healing, antiseptic and anti-inflammatory to respiratory and urinary tracts. Despite of the wide use of the oil of Copaifera species, scientific works related to the study of its leaves are rarely fou

5. Antiherpetic activity of a flavonoid fraction from Ocotea notata leaves
This study describes the isolation of a flavonoid fraction from leaves of Ocotea notata (Nees & Mart.) Mez, Lauraceae, the identification of six major compounds (an A-type proanthocyanidin trimer [3], isoquercitrin [4], reynoutrin [5], miquelianin [6], quercitrin [7], afzelin [8]) and four minor compounds (catechin [1], epicatechin [2], quercetin [9], kaempf

6. Isolamento e avaliação do potencial citotóxico de derivados fenólicos de Schinus terebinthifolius Raddi (Anacardiaceae)
The EtOH extract from leaves of S. terebinthifolius was subjected to partition between EtOH:H2O and hexane, CH2Cl2, and EtOAc. The phases obtained were evaluated in vitro against human tumoral cell lines and the EtOAc phase exhibited activity. Chromatographic procedures afforded gallic acid (1), methyl (2) and ethyl (3) gallates, trans-catechin (4), quercitr

7. Obtenção de produtos a partir das folhas de Copaifera langsdorffii Desf.: otimização da extração e secagem em spray dryer utilizando planejamentos experimentais / Obtainment of products from Copaifera langsdorffii Desf. leaves: extraction and spray drying optimization by experimental designs
A planta brasileira Copaifera sp. é uma árvore cujo óleo é tradicionalmente utilizado pela população principalmente como antiinflamatório, analgésico e relaxante muscular justificando o grande interesse científico em seu estudo. Entretanto, estudos tecnológicos, fitoquímicos e biológicos sobre suas folhas são escassos. Assim, este trabalho prop�
