Sweet potato, Nil, Nil, Lutein, Zeaxanthin


Sweet potato (Ipomoea batatas) is one of the most important food crops in the world. Sweet potato is rich with carotenoids and pro-vitamin A. Carotenoids compounds are commonly found in fruits and vegetables and are responsible for yellow, orange, and red pigmentations. Carotenoids are antioxidants compounds with pharmaceutical and medicinal benefits. Carotenoids such as α-carotene and β-carotene react as provitamin A in the human body, while lutein and zeaxanthin are two major components of the macular pigment of the retina.

Objective: The objective of this study is to verify the high nutritional value of Malaysian sweet potatoes varieties by identifying and comparing their carotenoids content.

Methods: Spectrophotometry and high performance liquid chromatography (HPLC) analysis were used to identifying and comparing carotenoids content quantitatively and qualitatively in orange, yellow, purple and white Malaysian sweet potatoes flesh tuber.

Results: The results of this study showed that the highest total carotenoid content was in orange sweet potato followed by yellow, purple and white sweet potato. β-carotene was available in all types of sweet potato ranging from 91.95±2.05 μg/g DW in white sweet potato to 376.03±11.05 μg/g DW in orange sweet potato. Detectable levels of zeaxanthin were appeared with values 5.44±3.23 μg/g DW and 20.47±2.03 μg/g DW in yellow and white sweet potato, respectively. Lutein was available only in orange sweet potato at trace amount of 0.91±1.03 μg/g DW. Purple sweet potato contains only β-carotene (113.86±14.17 μg/g DW) with absence of other carotenoids.

Conclusion: Total and individual carotenoids content vary between the flesh of these local sweet potato varieties. The results from this study can festoon the pharmaceutical, food and cosmetic industries markedly.
