Sesquiterpenoids from the fruits of Alpinia oxyphylla Miq. and their neuroprotective effect.

The purpose of this study was to identify sesquiterpenoids from Alpinia oxyphylla Miq. fruits under the guidance of LC-MS, and to evaluate their neuroprotective effects on the HO-induced SH-SY5Y cells. A total of 35 sesquiterpenoids, including 10 previously unreported ones, were isolated from A.
