Research on allelopathic interactions can be useful in the search for phytotoxins produced by plants that may be employed as natural herbicides. The aim of this study was to assess the phytotoxic action of aqueous leaf extract of Blepharocalyx salicifolius, Myrcia multiflora, Myrcia splendens and Myrcia tomentosa on the germination and development of three weeds. The working hypothesis was that...

OBJECTIVE Green tea (Gt), leafs of Camellia sinensis var. assamica, is widely consumed as healthy beverage since thousands of years in Asian countries. Chewing sticks (miswak) of Salvadora persica L. (Sp) are traditionally used as natural brush to ensure oral health in developing countries. Both Gt and Sp extracts were reported to have anti-bacterial activity against many dental plaque bacteria...

phytochemical screening, antioxidant and antibacterial activities of aqueous and methanolic crude extracts of commiphora kerstingii leaves were investigated. the antioxidant and antibacterial properties of different solvent extracts of commiphora kerstingii plant were scrutinized. the phytochemical screening of the various extracts was carried out using standard methods and the results revealed...

objectives insulin resistance has been considered as the most important component of type 2 diabetes mellitus (dm2). plants used in folk medicine to treat diabetes mellitus represent a viable alternative for the control of this disease. this study was aimed to examine the antidiabetic effects of three iranian medicinal plants i.e. urtica dioica, trigonella foenum-graecum and fumaria officinalis...

The objective of the study is to evaluate the hypoglycemic activity of Barringtonia acutangula (BA) fruit extracts i.e. aqueous, methanol and chloroform in streptozotocin (STZ) 50mg /kg induced hyperglycemic Wistar rats. In addition, the effect off all the three extracts of BA fruit on oral glucose tolerance in glucose loaded normal rats was also determined. Aqueous extract (400 mg/kg) treatmen...

Alcohol and aqueous extracts from the leaves of Argemone mexicana were investigated for their anthelmintic activity against Pheretima posthuma and Ascardia galli. Five concentrations (6.25, 12.5, 25, 50 and 100 mg/ml) of each extracts were studied in activity, which involved the determination of time of paralysis and time of death of the worms. Both the extracts exhibited significant anthelmint...

The in vitro antimicrobial activity of Cassia didymobotrya and Phlogacanthus thyrsiflorus leaf extracts were studied against selected bacteria and fungi following Agar disc diffusion method. Leaves were extracted using distilled water, methanol and ethyl acetate. Three different concentrations were applied to the disc (100μg, 250μg and 500μg/disc) for each extracts. While the aqueous extracts o...

Crude extracts of leaves and bark of E. jambolana were tested for antiviral activity against highly pathogenic avian influenza virus (H5N1) by CPE reduction assay in three different layouts to elucidate virucidal, post-exposure and preexposure antiviral activity of the extracts. The cold and hot aqueous extracts of bark and hot aqueous extract of leaves of E. jambolana showed significant viruci...

Department of Botany, Andhra University, Visakhapatnam (A.P) 530003, India. ABSTRACT The present investigation is aimed to carryout in vitro antibacterial activities of the methanol and aqueous extracts of Cleome viscosa against seven bacterial species. To evaluate antibacterial activity, the agar well diffusion assay was performed. Methanol extract was showed more antibacterial activity than a...
