The antiproliferative constituents in the MeOH extracts of the aerial parts of Lippia dulcis Trev. and Lippia canescens Kunth (Verbenaceae) were investigated. Activity-guided chemical investigation of the MeOH extracts resulted in the isolation of the three bisabolane-type sesquiterpenes [(+)-hernandulcin (1), (-)-epihernandulcin (2), and (+)-anymol (3)] and four phenylethanoid glycosides [acte...

Species boundaries in Lippia asperrima and turnerifolia complex (Verbenaceae)
 The specific of L. are discussed. contermina is accepted as segregated asperrima, while modesta Morongii rehabilitated the synonym turnerifolia. Lantana ovata var. hirsuta recognized new synonymies contermina, whereas trachyphylla treated cospecific modesta, asperima f. angustifolia reduced under Morongii. All s...

This study includes 10 samples isolated from a different source. research paper was to the antibacterial activity and antibiofilm of an alcoholic extract Lemon Myrtle (Backhousia citriodora) leaves, against clinical isolates Pseudomonas aerogenoza. Isolates were diagnosed by VITEK-2 compact system (PCR). The capacity produce biofilm tested using Microtiter plate technique (96 wells). results sh...

The pollen morphology and exine structure of 17 species of Lippia L. were investigated in this work using light and scanning electron microscopy. Among the species studied, 14 showed tricolporate pollen grains, two had tri- and tetracolporate pollen grains and a single species exhibited, only tetracolporate pollen. The amb ranged from triangular to square, and the shape varied from oblate-spher...

O objetivo desse trabalho foi avaliar a eficiência do extrato vegetal de eucalipto citriodora (Corymbia citriodora) sobre os danos por pragas e produtividade da cultura couve brócolis (Brassica oleracea). Foram testados quatro tratamentos: sem aplicação vegetal; aplicações na proporção 50% 100% e; 150%. avaliados nas folhas, área foliar atacada, massa inflorescência diâmetro das cabeças, couve....
