The petroleum ether fraction of Bupleuri Radix which is contained in the traditional Chinese medicine prescription of Xiaoyaosan (XYS) may have a therapeutic effect in depressed subjects based on the results of our previous study. It has been reported that Bupleuri Radix can cause liver toxicity following overdosing or long-term use. Therefore, this study aimed to decipher the differential effe...

Our previous study showed that Semen sojae germinatum (SSG), a soy-derived Chinese medicinal material, have potential benefits for knee osteoarthritis (OA). This study was undertaken to identify the major effective sub-fraction of SSG. The 95% ethanol extract of SSG was successively fractionated into petroleum ether, ethyl acetate, n-butanol and aqueous fractions. Then we examined the effect of...

Polar petroleum components enter marine environments through oil spills and natural seepages each year. Lately, they are receiving increased attention due to their potential toxicity to marine organisms and persistence in the environment. We conducted a laboratory experiment and employed state-of-the-art Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) to characterize the...

The persistent free radical content in petroleum is of the order 1018 spins/g (1 μmol/g), with higher and lower values found depending on origin different distillation fractions. field radicals was reviewed aim addressing explaining apparent inconsistencies between persistence reactivity. macroscopic average concentration over geological time, but individual species are short-lived reactive. ca...

several research groups have attempted to make recombinant bacteria capable of efficient desulfurization of oil fraction. the main aim of this study was to design a recombinant strain in order to desulfurize dibenzothiophen (dbt) and its components found in petroleum. in this study the pvlt31 vector harboring dszabc genes was transferred into recombinant e. coli bl21 which contained the dszd ge...

The aim of this study was to investigate the feasibility of using apple filter cake, a fruit-processing waste to enhance the bioremediation of petroleum contaminated soil. A rotating barrel system was used to study the bioconversion of the xenobiotic compound by natural occurring microbial population. The soil had been accidentally polluted with a total petroleum hydrocarbon concentration of 41...

Abstract Sesbania grandiflora leaves are extensively used locally since ancient time as in traditional systems. Base on mainly folkloric use, we investigated to know the potential of Sesbania grandiflora leaves extracts through biological works in vivo and in vitro. The ethanolic extract of S. grandiflora leaves was partitioned into ethyl acetate soluble fraction (ESF), petroleum ether so...

Plenty of medicinal plants are available in Pakistan and are in human use as herbal medicines from ancient time. Present work is based on the evaluation of the use of Malva parviflora in skin irritation problems. For this purpose, powdered plant material (The aerial part and roots separately) was extracted by using successive solvent extraction method using petroleum ether, chloroform and metha...
