Bioactive Compounds in Sweet Potatoes
Sweet potatoes are a good source of several bioactive compounds, above all (poly)phenols, terpenoids, tannins, saponins, glycosides, alkaloids, and phytosterols. The diversity of skin and flesh color in this root vegetable arises from the different levels of (poly)phenols and carotenoids. Thus, the dominant pigments in purple sweet potatoes are anthocyanins and phenolic acids, whereas, in yellow and orange-fleshed sweet potatoes, they are phenolic acids, flavonoids, and carotenoids. In addition to genetics, the concentration and bioavailability of bioactive compounds in sweet potatoes and derived products are affected by external factors such as environment and cultivar, storage conditions, and processing; moreover, the available data can be influenced by the extraction and analytical methods.
Phenolic Compounds
Sweet potatoes are characterized by a high concentration of flavonoids and phenolic acids. Flavonoids are mainly found in purple-fleshed potatoes in the form of anthocyanins and quercetin glycosides.
The sensory qualities of sweet potato are associated with their content of phenolic acids, namely chlorogenic, dicaffeoylquinic, caffeic, ferulic, p-hydroxybenzoic, coumaric, sinapic, syringic, and vanillic acids
Carotenoids
Sweet potato tubers are an excellent source of carotenoids, which contribute to their yellow and orange color. The total carotenoid content differs significantly according to the potato color and variety. β-carotene is the most abundant in those with orange flesh (more than 99% of total carotenoid content), whereas trans-β-carotene predominates in those with white and purple flesh.
