This study aimed to extract ethanol leaves. The were extracted by obtained with a yield 47%. was partitioned n-hexane solvents yields 5% (n-hexane) 65% (ethanol). leave identified phytochemica...

Background: Herbicides are widely used in agriculture to kill a large variety of unwanted weeds. However, the application in water ecosystems may pose harmful impacts on the health of aquatic organisms. We studied the acute toxicity of four major types of herbicides on the survival of adult shrimp, Artemia franciscana (AF). Methods: The brine shrimp, AF, was hatched from the commercially encys...

Extracts of Buyo (Piper betle L) were subjected to a bioscreening study detect cytotoxicity activity by the brine shrimp lethality bioassay. Specifically, researchers opted use stem part plant since there has been no about its cytotoxic activity. The result obtained for ethanol extract was promising. concluded that is most active in activity, with value 205.3525, against other extracts. This ca...

In this study, we assessed the antitumor activity of the methanol extract from wood chips of the heartwood of the Taiwan red cypress, Chamaecyparis formosensis Matsumura, which is a precious tree species endemic to Taiwan. A brine shrimp lethality test (BST) indicated that the ethyl acetate (EtOAc)-soluble extract from the MeOH extract was a suitable candidate (LC (50) = 15.36 microg/mL) for fu...
