8. Analysis of Antioxidant Activities Contained in the Boesenbergia pandurataSchult. Rhizome

Author

SHINDO, Kazutoshi, KATO, Miki, KINOSHITA, Asuka, KOBAYASHI, Asami, and KOIKE, Yukiko

Abstract

The rhizome of Boesenbergia pandurataSchult. was found to possess potent antioxidant activity in a rat brain homogenate model. Bioassay-guided isolation of the active compounds from a CH2Cl2–MeOH (1:1) extract led to the isolation of 5-hydroxy-7-methoxyflavanone, panduratin A, 5,7-dihydroxyflavanone, 2′,6′-dihydroxy-4′-methoxychalcone, 2′,4′-dihydroxy-6′-methoxychalcone, and 4-hydroxypanduratin A. Panduratin A, 4-hydroxypanduratin A, and 2′,6′-dihydroxy-4′-methoxychalcone were also found to exert neuroprotective effects.
