Determination of antioxidant and sun protection factor of plant curcuma xanthorrhiza (temulawak) / Norahsikin Mohd Saman

Antioxidants are substances that can fight and destroy excess free radicals and repair oxidative damage. Incorporation of antioxidant into a sunscreen may enhance its sun protection factor and at the same time provide protection from free radicals damage. The antioxidant activities of Curcuma xantho...
