Determination of oil palm fruit phenolic compounds and their antioxidant activities using spectrophotometric methods.

There is scarce information on the phenolics of oil palm fruits (Elaeis guineensis). In this study, phenolics were extracted from oil palm fruits and analysed using spectrophotometry for information on the different types of palm phenolics and their antioxidative activities. Analyses of the total ph...
