Stachytarpheta is the second largest genus of Verbenaceae, mainly distributed in xeric habitats South America. The morphological revision American specimens clarified taxonomic identity three previously accepted species from informal group Gesnerioides: S. sprucei (from Amazon Forest domain), alata, and tomentosa Atlantic domain). A new arrangement proposed here, with synonymization alata under...

The composition and pharmacological properties of Lippia alba (Mill.) (L. alba) (Verbenaceae) flower leaf essential oils (EO) were determined in this study. major constituents the EO geranial (49.83%) neral (32.75%), (38.06%), (31.02%), limonene (18.03%). Flower inhibited thrombolysis induced by Bothrops moojeni (B. moojeni) Lachesis muta muta) venoms (0.05-1.2 µL mL-1). When tested against L. ...

A comparative study of the chemical composition of essential oils of two very similar species of the Verbenaceae family (Lantana camara and L. radula) revealed that the main components of essential oil of L. camara were germacrene-D (19.8%) and E-caryophyllene (19.7%), while those of L. radula were E-caryophyllene (25.3%), phytol (29.2%) and E-nerolidol (19.0%). We have hypothesized that the ob...

The aim of the present study was to investigate the antimicrobial and preliminary phytochemical properties of Lantana indica Roxb. The aqueous and organic solvent (ethyl acetate and methanol) extracts from the leaves of Lantana indica (Verbenaceae) were tested against Staphylococcus aureus, Bacillus subtilis, Steptococcus pyrogens, Escherichia coli, Proteus vulgaris, Klebsiella pneumoniae, Pseu...

In the present study three medicinal plants Vitex negundo Linn (Verbenaceae), Bryophyllum pinnatum Linn (Crassulaceae) and Centella asiatica (Umbelliferae) reported to have significant analgesic potential were selected to be formulated as polyherbal gels with and without permeation enhancers and were investigated for their antinociceptive potential. The dried finely ground herbs were extracted ...

Callicarpenal and intermedeol are two insect-repellent terpenoids isolated from leaves of American beautyberry (Callicarpa americana L.; Verbenaceae) and Japanese beautyberry (Callicarpa japonica Thunb.). The repellency of these two terpenoids against workers of red imported fire ants, Solenopsis invicta Buren, black imported fire ants, Solenopsis richteri Forel, and a hybrid of these two speci...

Lantana camara L. (Verbenaceae) originates from tropical Central and South America and has become invasive in about 50 countries. It causes problems when invading rangelands due to its toxicity to livestock and its tendency to form dense, monotonous thickets. Its invasiveness can partly be explained by the high tannin content largely protecting the species from being browsed, its tolerance to a...

Stachytarpheta is one of the largest genera Verbenaceae, found mainly in campos rupestres Brazil. We describe a new species, lajedicola, and report for first time occurrence genus limestone outcrops. The species endemic to Caatinga domain, northern Minas Gerais state, growing an open karst formation municipality Matias Cardoso, locally known as Lajedão. Its main diagnostic characteristics are b...
