Mammea siamensis (Miq.) T. Anders. (Calophyllaceae) plants have long been employed as an active integral composition in Thai traditional medicine. Additionally, phenylcoumarins and triterpenes were reported major components phytochemical research. This work explored the various parts of M. siamensis; barks, flowers, twigs, leaves, young leaves; to determine their bioactive compounds. By using G...

Natural antioxidants found in marine macroalgae are bioactive compounds known to play an important role in the prevention of diseases associated with aging cells protecting them against the oxidative damage. The purpose of this study was to evaluate the antioxidant and cytotoxic activity of ethanolic extracts of two species of red seaweeds, Amansia multifida and Meristiella echinocarpa. In vitr...

Abstract. In the current studies, crude and subsequent fractions of Aconitum violaceum aerial parts were screened for their toxicity, antimicrobial effects as well antioxidant potential. Phytochemically, plant is enriched in alkaloids alongside anthraquinones (present ethyl acetate fraction (AV3) saponins (detected chloroform (AV2). Brine shrimp lethality assay, AV3 was most potent (59 %) killi...

the present study was intended to standardize the protocol for the synthesis of silver nanoparticles (agnps) using aqueous extract of dictyota bartayresiana j.v. lamouroux and evaluate cytotoxic potentials using brine shrimp bio-assay activity and trypan blue dye exclusion method. the reduction of pure ag+ ions was monitored by measuring the uv-vis spectrum of the solution at 200-900 nm and the...

Biofilm is a complex microbial community highly resistant to antimicrobials. The formation of biofilms in biotic and abiotic surfaces is associated with high rates of morbidity and mortality in hospitalized patients. New alternatives for controlling infections have been proposed focusing on the therapeutic properties of medicinal plants and their antimicrobial effects. In the present study the ...

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...

Tinospora crispa, a plant belonging to the family of Menispermaceae is a well-known traditional medicinal plant used in Bangladesh. The methanolic extracts of stems of the plant were evaluated for their thrombolytic and preliminary cytotoxic activities. The thrombolytic activity was evaluated using the in vitro clot lysis model while while the screening of cytotoxic activity was done using brin...

Euphorbiaceae is a family of plant spread in all parts of the world except very cold regions. The genus Euphorbia consists of over eighty-two species grown wildly in Iran. Some of Euphorbia species are used in the treatment cancer and tumors in different countries. The genus Euphorbia has been the source of a large number of biological active compounds. In this study petroleum ether, ether, eth...
