โœฆ Synopsis

Six novel diarylheptanoids bearing chalcone or flavanone moiety (1-6) were isolated from the seeds of Alpinia blephc~ocalyx K. Schum. Their structures were determined by spectroscopic analysis.

Stereo-chemical assignment of diarylheptanoid part of these compounds was done by NMR spectral analysis of their MTPA esters. These compounds inhibited nitric oxide (NO) production in endotoxinactivated murine macrophages, J774.1.
