The phytochemical investigation on the chloroform and ethyl acetate soluble fractions of Colebrookia oppositifolia Smith. led to the isolation of four new-source compounds namely 1pentacosanol (1), stigmast-7-ene-3β-ol (2), p-hydroxybenzoic acid (3), ursolic acid (4) and seven known compounds namely triacontane (5), triacontanol (6), betulonic acid (7), negletein (8), 5,2′,6′-trihydroxy-7-metho...

Seven indigenous medicinal plants, Mallotus philippensis, Pogostemon cablin, Colebrookea oppositifolia, Mussaenda macrophylla, Celosia argentea, Pilea symmeria and Thysanolaena maxima, have been investigated for their antimicrobial activity and antioxidant activity. The ethanol extract of these medicinal plants were subjected to evaluate their antibacterial properties and their antioxidant pote...

Thlaspi caerulescens J. & C. Presl is a distinctive metallophyte of central and western Europe that almost invariably hyperaccumulates Zn to > 1.0% of shoot dry biomass in its natural habitats, and can hyperaccumulate Ni to > 0.1% when growing on serpentine soils. Populations from the Ganges region of southern France also have a remarkable ability to accumulate Cd in their shoots to concentrati...

BACKGROUND Acokanthera oppositifolia Lam (family: Apocynaceae) is a shrub or small tree with white latex, and the leaves of this plant are used in the form of a snuff to treat headaches and in infusions for abdominal pains and convulsions and septicaemia. Adenia gummifera Harv of the family Passifloraceae is a distinctive woody climber whose infusions are used as emetics and are said to help wi...

The seed oil of Lesquerella fendleri is valued for its use in industrial products including lubricants, methyl esters for diesel fuel additives, greases, drying agents, plastics, nylon-11, surfactants and protective coatings. The predominate fatty acids in the seed oil of all Lesquerella species are hydroxy fatty acids (HFA) and the HFA found in L. fendleri, the species being developed as a new...

In the present study, we tested in vitro different parts of 35 plants used by tribals of the Similipal Biosphere Reserve (SBR, Mayurbhanj district, India) for the management of infections. From each plant, three extracts were prepared with different solvents (water, ethanol, and acetone) and tested for antimicrobial (E. coli, S. aureus, C. albicans); anthelmintic (C. elegans); and antiviral (en...

To conduct product development research on Lesquerella seed oils, we explored methods to obtain >100 g quantities of lesquerolic (14-hydroxy-cis-lleicosenoic) acid. Preliminary experiments with opencolumn silica gel chromatography showed that L. fendleri oil could be separated into 3 triglyceride (TG) fractions. The first (10%) contained nonhydroxy 16(13%) and 18-carbon acids (65% 18:1,2,3). Th...

Plants acquire micronutrients such as iron (Fe), zinc (Zn), manganese, or copper from soil. These micronutrients are often not readily available and they need to be mobilized to the proper free ionic form in order to be taken up by plant roots. Perhaps the only exception to this is the uptake of Fe by grasses, which have evolved a so-called strategy II uptake mechanism that involves the secreti...
