The essential oil of Lippia alba is reported as an antifungal against human pathogenic microorganisms but few articles report its use as an alternative to synthetic fungicides on green mould control. The objective of this study was to determine chemical characteristics of L. alba essential oil and its antifungal activity against green molds as an alternative to synthetic fungicides. Essential o...

The village of Zapotitlán de las Salinas is situated in the Valley of Tehuacán-Cuicatlán, Puebla, Mexico. Plant species used by the local inhabitants to treat gastrointestinal diseases were identified using ethnobotanical, ethnographic and taxonomic methods. Out of 119 interviews, 44 plant species were registered, of which the following are the most frequently used (listed in descending order):...

BACKGROUND AND AIMS Lippia scaberrima, an aromatic indigenous South African plant, with medicinal application, potentially has economic value. The production of essential oil from this plant has not been optimized, and this study of the chemico-morphological characteristics was aimed at determining the location of oil production within the plant. Furthermore, the locality of other secondary met...

The working area of a screen-printed electrode, SPE, was modified with the enzyme tyrosinase (Tyr) using different immobilization methods, namely entrapment with water-soluble polyvinyl alcohol (PVA), cross-linking using glutaraldehyde (GA), and cross-linking using GA and human serum albumin (HSA); the resulting electrodes were termed SPE/Tyr/PVA, SPE/Tyr/GA and SPE/Tyr/HSA/GA, respectively. Th...

Some common plants in India, which are also considered as weeds, proved to confer strong antimicrobial activity against many human pathogens. They are rich in a wide variety of secondary metabolites, viz. tannins, terpenoids, alkaloids, flavonoids, phenols and quinines. In this study, some urinary tract infecting human pathogenic strains and their non pathogenic laboratory strains collected fro...

The genetic diversity and population structure of Lippia origanoides, a species of the Verbenaceae family that shows promise as a crop plant, was investigated along an altitudinal gradient in the basin of the Chicamocha River in northeastern Colombia. The economic importance of the species, quality of its essential oils, and the fact that it is restricted to some few semiarid areas in northern ...

in this study, aerial parts of lippia citriodora kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). the essential oil isolated by hydro distillation for 3 h using a clevenger-type apparatus and the oil was analyzed by gc and gc-ms. the yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...
