The nutritional and bioactive values of Korean white lotus cultivars (Muan, Chungyang, and Garam)extracted with methanol, water, and acetone solvents were evaluated by the contents of their bioactive compounds and antioxidant activity determined by ABTS, CUPRAC, FRAP, DPPH, and β-carotene-linoleic acid assays. HPLC, fluorometry, and FTIR spectroscopy were employed for evaluation of polyphenols and fatty acids. All lotus cultivar extracts possessed high amounts of total phenolics, ascorbic acid, proteins, and fatty acids and exhibited high levels of antioxidant activity, which were higher in water than in organic solvents. The significant highest content of the above-mentioned indices and biological activity were recorded in the Chungyang cultivar. Therefore, all studied Korean white lotus cultivars and in particular Chungyang could be recommended as effective nutritional and bioactive products, however, after investigation on humans.
