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 ...

general toxicity, antiproliferative, antibacterial and antioxidant activities of caulerpa peltata j.v.lamouroux (caulerpaceae) collected from oman sea were investigated. dried, ground alga was soxhlet-extracted with hexane, dichloromethane and methanol successively. the methanol extract was subjected to vacuum liquid chromatography (vlc) fractionation on silica gel using a step gradient of diff...

The first synthesis of (+/-)-robinlin (1), a novel homo-monoterpene with strong bioactivity in the brine shrimp lethality test, was achieved by starting from 3-isobutyloxy-2,6,6-trimethyl-2-cyclohexen-1-one (2).

General toxicity, antiproliferative, antibacterial and antioxidant activities of Caulerpa peltata J.V.Lamouroux (Caulerpaceae) collected from Oman Sea were investigated. Dried, ground alga was Soxhlet-extracted with hexane, dichloromethane and methanol successively. The methanol extract was subjected to vacuum liquid chromatography (VLC) fractionation on silica gel using a step gradient of diff...

The methanol extract of leaves of Urena lobata (L) (Malvaceae) has been selected to determine the antioxidant and cytotoxic potentials. The crude extract were tested for in vitro free radical scavenging assays such as 1, 1 diphenyl-2-picryl-hydrazyl (DPPH). Total phenolic and flavonoids content of U. lobata were analyzed. The sample effectively scavenged free radical at all different concentrat...

Currently, several desalination facilities have been proposed to operate or are actually operating in California. These facilities' use of reverse osmosis (RO) may discharge hypersaline reject brine into the marine environment. The risks, if any, this brine would pose to coastal receiving waters are unknown. To test the toxicity of hypersaline brine in the absence of any additional toxic consti...

OBJECTIVE To evaluate the cytotoxicity and genotoxicity activity of Euphorbia hirta (E. hirta) in MCF-7 cell line model using comet assay. METHODS The cytotoxicity of E. hirta extract was investigated by employing brine shrimp lethality assay and the genotoxicity of E. hirta was assessed by using Comet assay. RESULTS Both toxicity tests exhibited significant toxicity result. In the comet as...

The present study was intended to determine the antioxidant, larvicidal, and cytotoxic potential of various extracts of Asplenium aethiopicum (Burm. f.) Becherer. Antioxidant potential of the extracts was determined by the DPPH radical scavenging, phosphomolybdenum, and scavenging of H2O2. Larvicidal activity of Asplenium aethiopicum was performed against the fourth instar larvae Culex quinquef...

Twelve extracts obtained from nine plants belonging to six different genera of Clusiaceae were analyzed against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus and Enterococcus faecalis) bacteria using the microdilution broth assay. Tovomita aff. longifolia, T. brasiliensis, Clusia columnaris, Garcinia madruno, Haploclathra paniculata, and Ca...

Aqueous and alcoholic extracts of curcuma amda roxb. rhizomes have been evaluated for its anti tumour activity in Swiss albino mice. Alcoholic extract exhibited more potent anti tumour activity than aqueous extract. In-vitro cytotoxicity studies were confirmed by brine shrimp bioassay method. A significant increase in the life span and a decrease in the cancer cell number and tumour weight were...
