Influence of light intensity and temperature on antioxidant activity in Premna serratifolia L.

Premna serratifolia has been used to treat inflammatory disorders because it was believed to have antioxidant properties. However, scientific research on this species is currently lacking. This work assesses the antioxidant activity of P. serratifolia in relation to light intensity and temperature....
