Biological Activities
Compounds
Geranium carolinianum serves as a significant source of the active chemical compounds gallic acid and ellagic acid. Researchers utilized High-Performance Liquid Chromatography (HPLC) to accurately measure and quantify these specific components within the plant. The study revealed that the concentrations of both gallic acid and ellagic acid undergo dynamic variations depending on the collection time. Specifically, the levels of these acids begin to rise during the flowering stage of the plant's life cycle. Ultimately, the highest concentrations of these valuable constituents are reached during the immature-fruit stage.
