Crude aqueous and ethanolic extracts of root tissue of red (Rd) and high-pigment (HP) beet (Beta vulgaris L.) strains exhibited antioxidant and phase II enzyme-inducing activities, and these extracts were fractionated using Sephadex LH-20 chromatography. These bioactivities tended to become co-enriched in early and late eluting fractions, comprising 5-25%(More)
Free-radical scavenging, reducing, and phase II enzyme-inducing activities of aqueous and 5% aqueous ethanol extracts of freeze-dried root tissue of four beet (Beta vulgaris L.) strains (red, white, orange, and high-pigment (red) phenotypes) were determined. Aqueous and ethanolic tissue extracts of the regular and high-pigment red phenotypes were most(More)
