Article abstract of DOI:10.1016/S0040-4020(97)00474-2

Six novel diarylheptanoids bearing chalcone or flavanone moiety (1-6) were isolated from the seeds of Alpinia blepharocalyx 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 endotoxin-activated murine macrophages, J774.1.
