AI Summary

Research published in Photochemistry and Photobiology identifies brachycerine, a major leaf glucoside alkaloid from the tree Psychotria brachyceras, as a promising natural sunscreen for human skin. The compound absorbs ultraviolet light and acts as a powerful antioxidant, shielding the plant’s photosynthetic machinery from UV damage. When applied to human skin, brachycerine could block UV effects, offering a plant‑derived alternative to conventional sunscreens.
