Essential oil of Lithraea molleoides (Vell.): chemical composition and antimicrobial activity BJM
Shimizu,Mario Tsunezi; Bueno,Leandro de Jesus Franco; Rodrigues,Rosa Fátima Oliveira; Sallowicz,Fabiano Augusto; Sawaya,Alexandra Christine Helena Frankland; Marques,Márcia Ortiz Maio.
Lithraea molleoides (Vell.) (Anacardiaceae) is a tree found in Brazil, Paraguay, Bolivia, Uruguay, Argentina and Chile. It is popularly used in the form of alcoholic extracts, decoctions and infusions for the treatment of cough, bronchitis, arthritis, diseases of the digestive system and as diuretic, tranquilizer, haemostatic and tonic agent. The objectives of this study were the extraction of the essential oil of the mature fruit, leaves and aerial parts of the plant and quantification of the yield thereof; the identification and quantification of the principal components of the essential oil and the determination of its antimicrobial activity against bacteria and yeast. The essential oil yield of the mature fruits was 1.0% but essential oil was not...

Selection of new clones of linalool chemotype from genetic recombination in Lippia alba Bragantia
Rufino,Elcio Rodrigo; Siqueira,Walter José; Marques,Márcia Ortiz Maio; Colombo,Carlos Augusto; Azevedo Filho,Joaquim Adelino; Martins,Antônio Lúcio Melo.
The aromatic and medicinal species Lippia alba is vigorous and rugged native to the South America (Atlantic Rainforest). Because it is an allogamous and self-incompatible species, natural populations have high morphological and chemical variability. This work had as objective to conduct a preliminary screening to identify new promising clones from a novel (recombinant) base population of Lippia alba with regard to its agronomic and phytochemical traits, using the linalool oil or chemotype as model. The two superior linalool clones, obtained by collection, were used as controls. Traits evaluated included: dry mass of leaves (DML), oil yield percentage (EOY%), oil production per plant (OP), and linalool percentage (LN%). Forty linalool chemotype clones were...
