1. “Arnicas” from Brazil: comparative analysis among ten species
Abstract The “arnicas” found in Brazil are examples of different species of the family Asteraceae used in popular medicine for its attributed anti-inflammatory action. Among the species known and used as “arnica” we selected: Calea uniflora Less., Chaptalia nutans (L.) Polák, Lychnophora ericoides Mart., Lychnophora pinaster Mart., Lychnophora salic

2. In vivo anti-hyperuricemic activity of sesquiterpene lactones from Lychnophora species
ABSTRACT Hyperuricemia is the main cause of gout, an inflammation induced by uric acid deposition in joints. Drugs available present side effects, so there is a need for new treatment alternatives. Lychnophora species are used in folk medicine to treat inflammation, rheumatism and muscle pain. Goyazensolide (10 mg/kg), eremantholide C (25 mg/kg) and lychnoph

3. How to analyze germination of species with empty seeds using contemporary statistical methods?
ABSTRACT Statistical analysis is considered an important tool for scientific studies, including those on seeds. However, seed scientists and statisticians often disagree on the nature of variables addressed in germination experiments. Statisticians consider the number of germinated seeds to be a binomially distributed variable, whereas seed scientists conver

4. Spatial and Temporal Variations in Secondary Metabolites Content of the Brazilian Arnica Leaves (Lychnophora ericoides Mart., Asteraceae)
The genus Lychnophora (Asteraceae) is a medicinal plant traditionally used as anti-inflammatory or analgesic agent. Its biological properties have been widely investigated and correlated with its chemical composition, which could be different between the species and even accordingly to the place and season of collection. In this work, it was investigated the

6. An UPLC-MS/MS Method for Determination of Vicenin-2 and Lychnopholic Acid in Rat Plasma and its Application to a Pharmacokinetic Study
Vicenin-2 (VIC) and lychnopholic acid (LA) are present in large amounts in hydroalcoholic extract from leaves of Lychnophora salicifolia, commonly known in the Brazilian Cerrado as "arnicão", a plant applied as topic anti-inflammatory and as a flavoring agent for the traditional spirit (cachaça). A new ultra-performance liquid chromatography-tandem mass sp

8. Spatial and Height Distribution of Harvested Rupestrian Field Species in Preserved and Cultivated Communities
ABSTRACT This study aimed to compare the spatial and the height distribution of three plant species between two rupestrian field communities, one preserved (A) and the other cultivated (B). One 50 × 100 m plot was delimited in each community and the populations of Eremanthus incanus, Lychnophora pinaster and Vellozia caruncularis were assessed for height an
