Characterization and Antioxidant Activity of Flavonoid Extract from Leaves of Adinandra nitida Merr. ex Li
摘要
Abstract
In order to develop Adinandra nitida Merr. ex Li(a kind of particular plant in China),flavonoid extract from leaves of A. nitida(FE) was obtained by traditional solvent extraction. By high performance liquid chromatograph(HPLC) and tandem electrospray ionization mass spectrometry(ESI-MSn), the major flavonoid in leaves was identified as camellianin A, whose content in FE was as high as 51.19%±1.13%. The flavonoid extract showed high antioxidant activity by measuring abilities of scavenging DPPH radicals and hydroxyl radicals. It also exhibited strong reducing power. These results revealed that FE could be served as a new natural antioxidant.关键词
