This study evaluated the antimicrobial activity of the crude ethanol extract and fractions from Eugenia uniflora L. leaves against Pseudomonas aeruginosa. A total of 72 P. aeruginosa isolated from patients of three hospitals in Goiânia and 8 standard strains were selected to test antimicrobial activity. The bacteria susceptibility profile against 15 antimicrobial agents was determined using the...

The crude extracts and its fractions of the flower of Tagetes erecta Linn. were tested for insecticidal activity against a stored product insect pest, Tribolium castaneum (Herbst). The chloroform fraction showed highest toxicity against both the larvae and adults of Tribolium castaneum followed by 50 petroleum ether fraction and ethanol extract. The LC values of chloroform fraction against firs...

Background: Woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. Stem and flower extracts are previously flourished for their antibacterial activity. Leaves are also equally important, which are preliminary screened for their bioactive components in present study. Objective: Evaluation of antibacterial activity of leaves of W. fruticosa and detection of the...

The antioxidant activities of the ethanol extract, its benzene and chloroform fraction from seed aril of Myristica malabarica (Myristicaceae) were assessed in an effort to validate the hepatoprotective potency of this plant. The extract and the fractions showed scavenging of 1, 1-diphenyl-2picrylhydrazyl (DPPH) radical and inhibition of ABTS radical in vitro. Antioxidant activities of the extra...

•g Purified wax•h as isolated by Anderson (1929), is a complex lipid extracted with chloroform from cultures of acid fast bacilli. Extracting the purified wax with boiling acetone, Asselineau (1951) obtained a soluble portion termed •gWax C•h and an insoluble residue, the •gWax D•h fraction. Likewise, the alcohol-ether soluble part of acid fast bacilli was classified into several fractions. •gP...

Background and objectives: Angiogenesis is essential for tumor survival. Inhibiting angiogenesis could be a mechanism for hindering tumor development. Numerous studies have now been focused on agiogenesis inhibitors and many of such studies have targeted plant materials. In the present study, Crocus pallasii subsp. haussknechtii has been evaluated for anti-angiogenesi...

The chloroform and alcohol extracts of e plats were screened against six bacteria viz staphylococcus aureus, Escherichia Coli, proteus mirablis, salmonella typhimurium, Pseudomonas aeruginosa and Klebsiella a aerogenes. Benzene-ethyl acetate (4:1) eluate of chloroform extract sowed activity against E.Coli, S.typhimurium and P.aeruginosa. The nbutanol extract of alcohol extract was active agains...

BACKGROUND Tuberculosis (TB) is a global health problem complicated by drug resistance and human immunodeficiency virus that has dramatically increased active TB. Several medicinal plants are used traditionally to treat TB in Ethiopia and investigating these plants is required as plants are an alternative source for development of new anti-TB drugs. The purpose of this study was to investigate ...

Preliminary investigations were carried out to evaluate the antidiabetic effects of the leaves of O. stamineus extracted serially with solvents of increasing polarity (petroleum ether, chloroform, methanol and water); bioassay-guided purification of plant extracts using the subcutaneous glucose tolerance test (SbGTT) was also carried out. Only the chloroform extract, given at 1 g/kg body weight...

Background and objectives: Cancer is a major health problem in the world. The aim of this study was to extract the flowers of Allium austroiranicum used by Iranian people as a condiment or for its medicinal effects followed by bioassay guided fractionation of the extracts and fractions, using anti-proliferative effects against ovarian and cervical cancer cells. <strong...
