Plants produce a diverse range of bioactive molecules, making them rich source of different types of medicines. In the present study the, In vitro antibacterial activity of 3 medicinal plants viz., Parthenium hysterophorus, Stevia rebaudiana and Ginkgo biloba were evaluated by using different solvent extracts. The extracts were tested against Escherichia coli, Pseudomonas aeruginosa, Klebsiella...

Parthenin (a sesquiterpene lactone) is a major constituent of parthenium hysterophorus –a noxious weed known for its environmental and health hazardous properties. . It is responsible for imparting the several properties to this weed such as allelpathy, autotoxicity and allergencity. Further, anticancerous, antiameobic and antimalarial properties of the weed are also credited to parthenin. The ...

Parthenium hysterophorus, an invasive alien weed, is spreading rapidly across various land uses in Nepal. To understand how Parthenium is spreading across land uses at local scale, occurrence of this weed was recorded and its’ coverage in percent estimated along trails and road network at every 100 meter distance in Kirtipur Municipality of Kathmandu valley. In addition, vegetation sampling was...

Climate change elements including elevated atmospheric carbon dioxide (CO2) concentration and soil salinity significantly impact weed biology management. In this study, we evaluated the performance of a highly invasive plant species, parthenium (Parthenium hysterophorus L.) grown at various levels (ranging from 0 to 16 dS m−1) two CO2 concentrations (ambient: 400 ppm elevated: 700 ppm). The ind...
