HPLC-ESI-MS Characterization of Certain Polyphenolic Compounds of Carica papaya L. Fruit Extracts and Evaluation of Their Potential Against Murine Schistosomiasis mansoni.

The antischistosomal activities of L. extracts were evaluated and the characterization of the active secondary metabolites of the defatted methanolic extract was performed using HPLC-ESI-MS. The plant fruit powders were extracted with 85% methanol and fractionated using organic solvents.

Antioxidant properties of methanolic extracts of the leaves of seven Egyptian Cassia species.

In the present study, antioxidant activity of methanolic extracts of the leaves of seven Egyptian Cassia species was investigated using two methods, the phosphomolyb-date method and 1,1 diphenyl-2-picrylhydrazyl radical (DPPH) scavenging activity method.· The results revealed that C. glauca is the most potent species and that the activity of other plant species decreases in the following order: C.
