The edible parts of 36 cultivars of pomegranate grown in China were collected to make comparisons of their major chemical compositions and potential bio-activities. The chemical compositions, especially the phenol contents of peels from these pomegranates were also determined using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q TOF MS). Besides, the triacylglycerol compositions and fatty acid profiles of oils from pomegranate seeds were identified and semi-quantified. As the results, pomegranates with deeper color of arils contented greater amounts of total phenolic components, total anthycanins, and greater antioxidant activities in general. The peels of all the pomegranate samples contented remarkable phenolic compounds. Individual results showed that pomegranate sample No. 27 has the greatest phenolic content and antioxidant activity, and could be recognized as the major direct edible cultivars of pomegranate. The peel of No. 7 cultivar of pomegranate has the greatest phenolic content, and No. 29 cultivar has the greatest triacylglycerol contents in pomegranate seed. Further development about the byproduct of these pomegranates after industrial processing should be focused on in the future.
