This paper reports on the composition of pigment compound in three cultivars 'Cara Cara’, 'Moro', and 'Tarocco’ of Citrus sinensis. The present study investigated the variation in anthocyanins, carotenoids, total polyphenol, and flavonoids, and antioxidant activity in peel and flesh of C. sinensis. The flavonoid and carotenoid compositions were campared with HPLC method. TA content were highest in ‘Moro’ flesh (17.179 mg/100 g). TC were highest in Tarocco peel(17.087 mg/100g) and β -cryptoxanthine were highest in ‘Tarocco’ flesh(439 ug/100 g). TF were highest in ‘Cara Cara’ peel (209.2 mg/100 g) and all cultivar materials had high levels of hesperidin(‘Cara Cara’ 3.32 g/100 g; ‘Moro’, 2.012 g/100 g; ‘Taroco’, 2.06 g/100 g). These components had the highest antioxidant activity in the ‘Cara Cara’ peel, which had the highest flavonoid content in ABTS radical scavenging activity, as these components had an effect on antioxidant activity. When ‘Cara Cara’ peel extract was treated with 250 ug/mL, more than 70% of the radical scavenging activity could be measured. Therefore, these results suggest that fruits of ‘Cara Cara’, “Moro’, and ‘Tarocco’ are significant sourcse of antioxidant compounds such as phenolics, flavonoid, and β -cryptoxanthin.

스위트 오렌지(Citrus sinensis) ‘Cara Cara’ navel orange, ‘Moro’ blood orange, ‘Tarocco’ blood orange에 포함되어 있는 색소 성분인 anthocyanin, carotenoid, flavonoid를 분석하였다. Anthocyanin은 과육에서 함량이 높았으며 특히 ‘Moro’ 과육(17.179 mg/100 g)에서 가장 높았다. Carotenoid와 flavonoid는 과피에서 함량이 높았 고, carotenoid는 ‘Tarocco’ (17.087 mg/100 g)에서 가장 높았으며, carotenoid 중 β-cryptoxanthin을 439 ug/100 g 함유하고 있었다. Flavonoid는 ‘Cara Cara’(209.2 mg/100 g)에서 높았으며, HPLC를 이용한 플라보노이드 분석에서는 ‘Cara Cara’ (3.32 g/100 g), ‘Moro’ (2.012 g/100 g)와 ‘Tarocco’ (2.06 g/100 g)은 hesperidin의 함량이 가장 높았다. 이러한 성분들은 항산화 활성에 영 향을 미쳐 ABTS radical 소거 활성을 측정하였 을 때 플라보노이드 함량이 가장 높았던 ‘Cara Cara’ 과피에서 가장 높은 항산화 활성을 보여 ‘Cara Cara’ 250 ug/mL로 처리했을 때 70% 이상 의 radical 소거 활성을 확인할 수 있었다.
