Английская Википедия:Dark opal basil
Dark opal basil is a cultivar of Ocimum basilicum (sweet basil), developed by John Scarchuk and Joseph Lent at the University of Connecticut[1] in the 1950s. With deep purple, sometimes mottled leaves, it is grown as much for its decorative appeal as for its culinary value. Dark opal basil was a 1962 winner of the All-American Selection award.[2][3]
Like other purple basils, the purple color is from anthocyanins, especially cyanidin-3-(di-p-coumarylglucoside)-5-glucoside but also other cyanidin based and peonidin based compounds. 'Dark opal', along with other large leaved purple cultivars such as 'Purple Ruffles', has a high concentration of anthocyanins and is considered a potential source of red pigments for the food industry. The anthocyanin concentration is about 18 mg per 100 g fresh leaves, similar to Perilla frutescens, and greater than smaller leaved purple basils such as 'Purple bush' (at about 6 mg per 100 g).[4]
