The present study aimed at the phytochemical examination and anti-solar activity of Psidium guajava
(leaf) aqueous extract has more flavonoid content based on this chemical substance photo protective activity was evaluated using UV visible spectrophotometry, where the method is diffused transmittance and the range of UV-visible about 200-400nm.
Methods: The pulverized dried Psidium guajava leaves were extracted with distilled water using soxhlet apparatus. Aqueous extract were filtered & evaporated to dryness. The photo protective activity was evaluated by using UV visible spectrophotometry, where the method it is diffused transmittance and the range of UV-visible about 200-400nm.
Results: The UV scanning absorption spectra of the extract showed very strong absorption at 0.279A with-max at 268 nm.
Conclusion: The extract has an ability to absorb in the entire UV range.
