Psidium littorale
Psidium littorale
Psidium littorale, commonly known as coastal guava or beach guava, is a plant native to tropical and subtropical regions. While it has not been traditionally used in any specific medicinal practices, research has identified several bioactive compounds from this species. Scientific studies have shown potential cytotoxic and neuroprotective activities from compounds isolated against Alternaria alternate. Additionally, polysaccharides from Psidium littorale were found to exhibit higher predicted anti-glycated activity compared to those from Psidium guajava. The review also identified four megastigmane glycosides and three lignans for the first time in its leaves, contributing to a broader understanding of its chemical composition with possible Alzheimer's-related activities. No major safety issues or drug interactions have been recorded, but further research is needed to validate these findings comprehensively.
