Meloside A (Isovitexin 2''-O-glucoside) is a phenylpropanoid isolated from barley with antioxidant activity. In barley, phenylpropanoids have been described as having protective properties against excess UV-B radiation and have been linked to resistance to pathogens[1][2]. | [Definition]
ChEBI: 2''-O-(beta-D-glucosyl)isovitexin is a disaccharide derivative that is isovitexin substituted at position 2'' on the glucose ring by a beta-D-glucosyl residue. It has a role as a metabolite. It is a C-glycosyl compound, a disaccharide derivative and a trihydroxyflavone. It is functionally related to an isovitexin. | [References]
