What can lesser‑known Hypericum species offer?
A comparative study of phytochemicals, antioxidants, and phototoxicity
Most research focuses on Hypericum perforatum, yet the genus includes hundreds of species. This study examines whether other Hypericum plants share relevant bioactive properties.
Original article: Phytochemical profiles, phototoxic and antioxidant properties of eleven Hypericum species — A comparative study, 10.1016/j.phytochem.2018.05.003, https://www.sciencedirect.com/science/article/pii/S0031942218301353
Q&A What was analysed? Eleven Sicilian Hypericum species, focusing on their chemical composition and in vitro antioxidant and phototoxic activities.
Why compare multiple species? To identify alternative sources of bioactive metabolites beyond the traditionally used H. perforatum.
Key results • Identification and quantification of 20 bioactive metabolites • Antioxidant activity observed in all species • Several species showed notable photo‑induced cytotoxicity • Chemical diversity limits immediate chemotaxonomic applications
