  Neuroprotective constituent from the seeds of Alpinia katsumadai Hayata

  摘要：

  Two new compounds, named as rhamnocitrin-3-O-beta-D-glucopyranosyl-4'-O-beta-D-galactosyl-(1 -> 3)-O-b-beta D-glucopyranoside (1), and (3R)-5,6,7-trihydroxy-3-isopropyl-3-methylisochroman-1-one (2), were isolated from the seeds of Alpinia katsumadai Hayata. Their structures were elucidated on the basis of spectroscopic analysis. Additionally, compounds 2 exhibited potent neuroprotective activity on 1-methyl- 4-phenylpyridinium-induced oxidative damage in PC12 cells. (C) 2016 Phytochemical Society of Europe.
