Melastoma malabathricum (MM) is a well-known plant in Malaysian traditional medicine, locally known as senduduk. Its ethanol and aqueous extracts have been used in the present investigation to study the immunomodulatory role on human peripheral blood mononuclear cell (PBMC), and the DPPH, ABTS and FRAP free radical scavenging activities were also measured. Total flavonoids and total phenolic co...

This study investigated the antibacterial activities of hot water, ethanol and acetone extracts of Jatropha curcas (LINN) leaves on coliforms isolated from surface waters using growth inhibition indices based on agar plate technique. The percentage recovery of the extracts was 19.17%, 18.10% and 18.80% for hot water, ethanol and acetone respectively. Phytochemical screening of the extracts was ...

Issued 6 January 2006 ABSTRACT The antifungal activities of the ethanol and aqueous crude extracts of four Nigerian chewing sticks were investigated. Also a preliminary phytochemical analysis of the plants was done. The chewing sticks include Anogeissus schimperi, Distemonanthus benthmianus, Vernonia amagdalina and Xanthoxylum zanthoxyloides. All the plants tested, except Anogeissus Schimperi, ...

Water and alcoholic extracts of Crotalaria juncea L. plant were tested for their antimicrobial properties in vitro against some selected human pathogenic bacteria such as Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus by agar well diffusion method and were subjected to brine shrimp lethality assay to detect their cytotoxic ability. In addition, the anticancer properties of ...

The present study was aimed to investigate the diuretic effects of aqueous and crude ethanol extracts of Bombax ceiba L. fruits (family, Bombacaceae) using acute model in rats. A single individual dose of aqueous and ethanol extract of B. ceiba fruit (200 mg/kg and 400 mg/kg, p.o., each), frusemide and hydrochlorothiazide, (25 mg/kg, p.o., each) as reference diuretic drugs, were administered or...

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...

Petroleum ether (60-80°C), chloroform, ethyl acetate, ethanol and aqueous extract of aerial parts of Melothria heterophylla Lour. were evaluated separately for anthelmintic activity on adult Indian earthworms (Pheretima posthuma), using albandazole and piperazine citrate as reference standards. The results indicated that the ethanol extract of M. heterophylla Lour (EEMH) was more potent than th...

Objective: The objective of the present study was to evaluate antioxidant and free radical scavenging activity of various extracts of Rose flower petals. Methods: Chloroform, acetone, ethan...

BACKGROUND Pycnocycla spinosa (P. spinosa) a member of the Umbelliferae family is traditionally used for treatment of different ailments. OBJECTIVES This study aimed to evaluate the total phenolic and flavonoid content of P. spinosa extracts (methanol, ethanol and aqueous) and their antioxidant and antimicrobial effects. MATERIALS AND METHODS The antimicrobial activity of different extracts...

A total of ten biological compounds were isolated from the leaves of Barleria montana Nees. by using GC-MS analysis. Among them, the Benzaldehyde,2-hydroxy-6-methyland Urs-12-en-24-oicacid,3-oxo-,methyl ester,(+)as major compounds. The aqueous and different solvent extracts (acetone, chloroform, di-chloromethane, ethanol and methanol) of the plant were tested for antibacterial activity against ...
