Objectives Malva sylvestris L., known as common mallow, is native to Europe, North Africa and Asia. In the Mediterranean region, this species has a long history of use as food, and due to its therapeutic relevance, some parts of this plant have been employed in traditional and ethnoveterinary medicines. The leaves in particular have been reported to have potent anti-inflammatory, antioxidant, anti-complementary, anticancer and skin tissue integrity activity. Additionally, an anti-ulcerogenic effect was recently proven, demonstrating that the aqueous extract was more effective than cimetidine, a potent medicine used to treat gastric ulcers. Due to its wide use and medicinal importance, many studies have been conducted; however, the information in the literature is very extensive and disseminated, making it difficult to use. Key findings A complete review involving the ethnobotanical and scientific aspects of M. sylvestris has been made. The research has provided evidence that M. sylvestris has potential use as a medicinal plant and has highlighted a need for more studies involving clinical and toxicological aspects of its use. Summary This review can contribute to the field with its historical context, and by describing the progress made, new ideas for researchers can arise.

RESUMO:No Brasil as espécies de Mikania glomerata Spreng. e M. laevigata Sch. Bip. ex Baker, Asteraceae, popularmente conhecidas como guaco, são amplamente utilizadas com evidências pré-clínicas para o tratamento de doenças onde estejam envolvidas suas ações broncodilatadoras, antialérgicas, antiasmáticas, anti-inflamatórias, antiulcerogênicas e relaxantes da musculatura lisa. Em virtude das propriedades terapêuticas atribuídas as essas espécies, ambas foram oficializadas na farmacopéia brasileira, e por serem bastante semelhantes, dificilmente são diferenciadas. Com o objetivo de contribuir com novas pesquisas, a presente revisão descreve, de forma sistematizada, sobre os aspectos farmacológicos, toxicológicos, químicos, agronômicos, morfoanatômicos, genéticos e o uso nos programas de fitoterapia do Brasil destas espécies. As principais diferenças e semelhanças entre as duas espécies são evidenciadas através da comparação das informações baseadas na literatura específica.Unitermos: Asteraceae, Mikania glomerata, Mikania laevigata, guaco, plantas medicinais.ABSTRACT: "Mikania glomerata Spreng. e M. laevigata Sch. Bip. ex Baker, Asteraceae: agronomic, genetic, anatomical, chemical, pharmacological, toxicological studies and its use in herbal therapy programs in Brazil." In Brazil the species of Mikania glomerata Spreng. and M. laevigata Sch. Bip. ex Baker, Asteraceae popularly known as guaco, are widely used with preclinical evidence for the treatment of diseases whose actions involve bronchodilators, antiallergic, anti-asthmatic, anti-inflammatory, antiulcerogenic and smooth muscles relaxant. Due to the therapeutic properties attributed to these species, both were included in the official Brazilian Pharmacopoeia, and because of their similarity, they are hardly differentiated. In order to contribute to the new research, this review describes their several aspects: pharmacology, toxicology, chemical, agricultural, anatomical, genetics and the use in herbal medicine programs in Brazil, in a systematic way. The main differences and similarities between the two species are evidenced by comparing the information based on literature.

Invasive aspergillosis is an opportunistic infection that is mainly caused by Aspergillus fumigatus, which is known to produce several secondary metabolites, including gliotoxin, the most abundant metabolite produced during hyphal growth. The diagnosis of invasive aspergillosis is often made late in the infection because of the lack of reliable and feasible diagnostic techniques; therefore, early detection is critical to begin treatment and avoid more serious complications. The present work reports the development and validation of an HPLC-MS/MS method for the detection of gliotoxin in the serum of patients with suspected aspergillosis. Chromatographic separation was achieved using an XBridge C18 column (150×2.1 mm id; 5 mm particle size) maintained at 25°C with the corresponding guard column (XBridge C18, 10×2.1 mm id, 5 mm particle size). The mobile phase was composed of a gradient of water and acetonitrile/water (95∶5 v/v), both containing 1 mM ammonium formate with a flow rate of 0.45 mL min−1. Data from the validation studies demonstrate that this new method is highly sensitive, selective, linear, precise, accurate and free from matrix interference. The developed method was successfully applied to samples from patients suspected of having aspergillosis. Therefore, the developed method has considerable potential as a diagnostic technique for aspergillosis.
