Contribuição ao conhecimento químico de plantas do nordeste - Lippia sidoides Cham

The present review focus in quinones found in species of Brazilian northeastern Capraria biflora, Lippia sidoides, Lippia microphylla and Tabebuia serratifolia. The review cover ethnopharmacological aspects including photography of species, chemical structure feature, NMR datea and biological properties. Chemical transformations of lapachol to form enamine derivatives and biological activities are discussed.

Pepper-rosmarin (Lippia sidoides Cham.) is a native medicinal plant from the Brazilian biome Caatinga. Its high economical importance comes from the antimicrobial properties of thymol and carvacrol, both present in the pepper-rosmarin essential oil. Nodal segments of pepper-rosmarin were established in vitro to evaluate different growth regulators. We tested four concentrations of IBA (0.0; 0.01; 0.05; and 0.1 mg L-1) combined with six concentrations of BAP (0.0; 0.1; 0.5; 1.0; 2.0; and 4.0 mg L-1) in assay 1; five concentrations of NAA (0.0; 0.1; 0.25; 0.5; and 1.0 mg L-1) in assay 2; two concentrations of NAA (0.0 and 0.01 mg L-1) combined with five concentrations of kinetin (0.0; 0.25; 0.5; 1.0; and 2.0 mg L-1) in assay 3; five concentrations of IAA (0.0; 0.5; 1.0; 1.5; and 2.0 mg L-1) in assay 4; and five concentrations of GA3 (0.0; 0.1; 0.5; 1.0; and 1.5 mg L-1) in assay 5. The use of BAP, IBA, NAA and KIN did not influence the number of shoots. The addition of 0.1 mg L-1 of NAA at the culture medium resulted in larger shoot length per explant, while the concentration of 1.0 mg L-1 of kinetin promoted larger shoot length in general. GA3 did not affect the elongation of pepper-rosmarin shoots when cultivated in vitro.
