The methanolic, aqueous and petroleum ether extracts of the root tubers of Gloriosa superba were studied for antibacterial, antifungal and mutagenic activities. Results showed that the petroleum ether extracts were highly active against the Gram-negative bacteria, Escherichia coli, Proteus vulgaris and Salmonella typhi at 50 μg/ml and active at 1000 μg/ml against Gram-positive bacteria. All ext...

From the flowers of meadowsweet and inflorescence of hawthorn the whole set of phenolic acids and flavonoids was analysed by TLC. Phenolic compounds were determined both as free ones and those liberated by hydrolysis. Moreover, ethyl ether and ethyl acetate extracts obtained from the analysed plants before and after alkaline and enzymatic hydrolyses were evaporated under reduced pressure and re...

A comprehensive inventory of the organic components and aroma-active compounds produced by Antrodia camphorata during growth in submerged culture has been established by extracting culture fluids using three different organic solvent systems and subjecting the extracts to gas chromatography–mass spectrometry (GC–MS) and gas chromatography–olfactometry (GC-O). Forty-three organic components, of ...

Barringtonia acutangula (L.) Gaertn belonging to family Barringtoniaceae was investigated to evaluate In vitro antibacterial activity of aqueous, ethanolic, petroleum ether and chloroform extracts against Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterococcus faecalis and Escherichia coli the major urinary tract infection causing pathogens were tested by disc diffusi...

Chloroform and methanol root and shoot extracts of A. aspera showed good amount of antibacterial activity against Klebsiella sp. While pet. Ether (60-80°) root extract showed the activity against B. Substilis only antifungal activity of roots was found in extracts with pet ether, chloroform and methanol against fusarium sp. only. Methanol and Aqueous shoot extracts were weakly active against Pe...

THE LEAVES EXTRACTS OF TWO INDIGENOUS PLANTS OF ETHIOPIA: Clematis longicauda steud ex A. Rich. and Clematis burgensis Engl. are used in Southwestern Ethiopia to treat otorrhoea and eczema. Antimicrobial activity and MIC of crude extracts were determined by disk diffusion and broth dilution. Phytochemical screening was performed on the extracts. The methanol and petroleum ether extracts of both...

Background: Plants contain diverse phytochemicals with different solubility levels, depending on their molecular charges and polarity. This study was conducted to examine the effects of three extraction solvents in their pure and aqueous forms: absolute petroleum ether, acetone and ethanol on the phytochemical profile and antioxidant activities of Manihot esculenta leaves extracts. Methods: Th...

In the present study deals with the antimicrobial properties of the Andrographis neesiana were tested against five human bacterial pathogens by using five various solvent namely, ethanol, methanol, acetone, chloroform and petroleum ether. The maximum antimicrobial activity was noted in petroleum ether extracts of stem showed activity against Escherichia coli (16mm) and the minimum was recorded ...

The preliminary phytochemical study and invitro antimicrobial activity of Coriander sativum (Apiaceae) was investigated against some pathogens isolated from patients with infectious diarrhea. The various solvents extract like aqueous, methanol, chloroform, petroleum ether and hexane were screened for antimicrobial activity against Enterotoxigenic E.coli, Enteropathogenic E.coli,, Salmonella typ...

The antimicrobial activity and the MIC values of the diethyl ether, acetone, chloroform, petroleum ether, and ethanol extracts of the lichen Hypogymnia tubulosa and its 3-hydroxyphysodic acid constituent have been investigated against some microorganisms. At least one of the extracts or 3-hydroxyphysodic acid showed antimicrobial activity against Aeromonas hydrophila, Bacillus cereus, Bacillus ...
