Eight marine cyanobacteria strains of the genera Cyanobium, Leptolyngbya, Oscillatoria, Phormidium, and Synechococcus were isolated from rocky beaches along the Atlantic Portuguese central coast and tested for ecotoxicity. Strains were identified by morphological characteristics and by the amplification and sequentiation of the 16S rDNA. Bioactivity of dichloromethane, methanol and aqueous extr...

A follow-up chemical investigation to methanol extract of Conyza dioscoridis (Family Asteraceae) led to the isolation of seven compounds (1-7). The isolated compounds identified as 2-(3,4-dihydroxyphenyl)ethyl-2-O-[6-deoxy-α-Lmannopyranosyl-4-(3,4-dihydroxyphenyl)-2-propenoate]-β-D-glucopyranoside (1), rutin (2), isoquercetin (3), E-caffeic acid (4), gallic acid (5), quercetin (6), β-Sitosterol...

Numerous studies have been focused on natural anticarcinogenic agents. Many antioxidants have been identified as anticarcinogens. Antimutagens have also been proposed as cancer chemopreventive agents. The use of natural products as anticancer has a long history that began with traditional medicine. The aim of this study was to evaluate cytotoxicity and antioxidant activity of twenty-three plant...

The in vitro activity of the petroleum ether extract of fruit part of Phyllanthus acidus was tested for cytotoxic antibacterial and antioxidant activities as well as for phytochemical screening. The plant was collected from Savar, Dhaka. Phytochemical screening of petroleum extract of phyllanthus acidus revealed the presence of carbohydrate, glycoside and steroid. The extract exhibited antibact...

We evaluated the antibacterial activity and cytotoxicity of endophytes isolated from Scapania verrucosa Heeg., which belongs to the liverwort class. A total of 49 endophytic fungi were isolated from S. verrucosa and classified into seven genera and one family in our previous study. In this study, the cytotoxic activity of the endophytes was assessed using the brine shrimp lethality bioassay, se...
