The work reports antibacterial and antifungal activity of different solvent extracts of Origanum vulgare. The antimicrobial activity of methanol, chloroform and aqueous extracts were determined against nine different gram negative and gram positive bacterial strains and three fungal stains. The bacterial strains were Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 29213), Micrococcus...

This work evaluated the antimicrobial activity of the methanol and chloroform extracts of the leaves of Miconia cabucu, Miconia rubiginosa, and Miconia stenostachya using the disc-diffusion method. The results obtained showed that the methanol extracts of the leaves of M. rubiginosa and M. stenostachya and the chloroform extract of the leaves of M. cabucu presented antimicrobial activity agains...

Two new phorbol-type diterpene esters have been isolated from the chloroform extract of the leaves of Synadenium grantii Hook F. and identified as 3,4,12,13-tetraacetylphorbol-20-phenylacetate and 4deoxyphorbol-12,13-ditiglate for which the trivial names Synagrantol A & B respectively, were adopted. Furthermore, two known triterpenes were isolated. The structures of all isolated compounds were ...

Lupeol (1), epilupeol (2) and β-sitosterol (3) were isolated from the n-hexane and the carbon tetrachloride soluble fraction of a methanol extract of the leaves of Phoenix paludosa Roxb. The n-hexane, carbon tetrachloride and chloroform soluble materials from the concentrated methanol extract were subjected to antimicrobial screening and brine shrimp lethality bioassay. All of the partitionates...

The penguin wing oyster Pteria penguin whole body extract was obtained with different solvents. The whole body extracts were assayed for antibacterial activity using agar well diffusion technique against human pathogens. The extracts derived from acetone and chloroform exhibited broad antibacterial activity. Highest activity was exhibited against Klebsiella pneumoniae (6 mm) and Staphylococcus ...

Many plant crude extracts and their isolated compounds are the most attractive sources of new drugs and show promising results for the treatment of gastric ulcers. Austroplenckia populnea is commonly known as "marmelinho-do campo, mangabeira-brava, mangabarana and vime" and it has been used in folk medicine as anti-dysenteric and anti-rheumatic. Powdered bark wood (3.25 kg) was macerated with a...

OBJECTIVE To investigate the protective effects of hydroalcoholic and its fractions from roots of Hemidesmus indicus on arthritis in in vitro models of rodents. METHODS Preliminary phytochemical analysis and thin-layer chromoatography were performed to analyze constituents of hydroalcoholic extract and its three fraction namely ethyl acetate fraction, chloroform fraction and residual fraction...

The aim of this reasearch is to investigate the effects of various extracts of Tongkat Ali on uric acid excretion and renal function in rats with hyperuricemia. Sprague dawley male rats were fed with yeast extract, adenine and potassium oxonate to make the model of rats with hyperuricemia. With the animal model being made, Rats were given various extracts from Tongkat Ali for 14 d. Then, uric a...

Syzygium jambos (L.) Alstone belonging to the Myrtaceae family have been investigated for evaluation of their biological activities namely antioxidant and antimicrobial activity. The n-hexane, carbon tetrachloride, chloroform, aqueous soluble fractions of methanolic extract as well as crude methanolic extract of stem barks of Syzygium jambos were evaluated for their free radical scavenging acti...

Berberis integerrima is a member of Berberidaceae family. Berberine is one of the main constituents of this plant, having neuroprotective effect on central nervous system diseases. In this study, the anticonvulsant activity of methanolic extract, and hydromethanolic fraction, and chloroform fraction of B integerrima was assessed. The anticonvulsant effect of B integerrima was investigated using...
