1. Distribution of metabolites in galled and non-galled leaves of Clusia lanceolata and its antioxidant activity
Essential oils of galled and non-galled leaves of Clusia lanceolata Cambess., Clusiaceae, were obtained by hydrodistillation and analyzed by GC and GC/MS. The chemical composition of both oils was similar, with a predominance of sesquiterpene caryophyllenes. The extracts from the leaves were evaluated regarding total phenols, flavonoids and proanthocyanidins

2. Antimicrobial mouthrinse use as an adjunct method in peri-implant biofilm control
Great possibilities for oral rehabilitation emerged as a result of scientific consolidation, as well as a large number of dental implant applications. Along with implants appeared diseases such as mucositis and peri-implantitis, requiring management through several strategies applied at different stages. Biofilm accumulation is associated with clinical signs

4. Variabilidade química dos óleos essenciais e do teor de fenóis em folhas e frutos da jabuticabeira (Myrciaria cauliflora) / Chemical variability of essential oils and phenol content in leaves and fruits of jabuticabeira (Myrciaria cauliflora)
Foliar contents of total phenols and tannins and the essential oil composition of Myrciaria cauliflora populations cultivated in six sampling sites have shown the presence of four clusters related to soil types and foliar nutrients. Cluster I included samples which originated from sandy soil (S1) with the highest and lowest percentages of γ-eudesmol (11

6. Influence of spatial, edaphic and genetic factors on phenols and essential oils of Myrciaria cauliflora fruits
A composição química dos óleos essenciais e o conteúdo em fenóis (fenóis totais, taninos e antocianinas) bem como os teores de açúcares redutores e da acidez dos frutos de M. cauliflora foram obtidos de plantas cultivadas sob seis tipos de solo. As análises de redundância canônica (RDA) e de discriminante indicaram a presença de quatro grupos de

7. Toxicity of ethanolic extracts from Lippia origanoides and Gliricidia sepium to Tetranychus cinnabarinus (Boisduval) (Acari: Tetranychidae)
Botanical compounds with insecticidal and acaricidal activities have been used in pest management with different levels of success. Toxicity of ethanolic extracts obtained from wild oregano (Lippia origanoides) and gliricidia (Gliricidia sepium) to Tetranychus cinnabarinus (Boisduval) were evaluated. Mite population was collected from black bean plants growi
