Ecotypic variation of a medicinal plant Imperata cylindrica populations in Taiwan: mass spectrometry-based proteomic evidence

Cogon grass [Imperata cylindrica L. Beauv. var. major] is the only one species of Imperata, and one of the medicinal plants in Taiwan. The rhizome can be used for medicinal purposes. In the field alcohol dehydrogenase (ADH) activity, proline and sodium content in tissues of Imperata showed variation between wetland (Chuwei population) and the other two representative non-wetland ecotypes (Neihu and Sarlun...

Antioxidant and antimicrobial activity of seed from plants of the Mississippi river basin

Seeds of native and naturalized plants currently found in the Mississippi River Basin of the United States were evaluated as potential new sources of antimicrobial and antioxidant activity. Methanol extracts of seeds were tested for antioxidant levels using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant assay and for antimicrobial activity using a disk diffusion assay againstStaphylococcus aureus, Pseudomonas...
