Medical compounds and the antioxidant capacity of aqueous extracts of Apocynum venetum L. in Xinjiang, NW China
Content of selected nutrients and antioxidant activity based on the Folin–Ciocaltau assay, the DPPH assays, and the ferric-reducing antioxidant power assay was determined in samples of Apocynum venetum L., Chinese herbal plant. Results for different parts of plant or different sampling sites were compared and determination of some phenolic compounds was performed. The found antioxidant activity is similar to other commonly used herbal teas; the total phenolic content is comparable to that of green and black teas.
