Abstract
Two novel diphenylheptanes, 2,3- dihydro-2 - (4′ - hydroxy-phenylethyl) - 6 - [(3″,4″ - dihydroxy-5“ - methoxy) phenyl] -4 - pyrone (CG-A) and 4 - dihydro-2 - (4’ - hydroxy-phenylmethyl) -6 - [(3”,4″ - dihydroxy-5″ - methoxyphenyl) methylene]-pyran-3, 5 - dione (CG-B), were isolated from the dried fruits of Amomum tsaoko, a commercially important spice. This study was designed to investigate their protective effects against H2O2-induced nerve injury, using PC-12 cells to determine the cell cytotoxicity and cell viability. The inhibitory effect on (nitric oxide) NO production was also determined in (lipopolysaccharide) LPS-stimulated macrophage RAW 264.7 cells. The results showed that CG-A and CG-B displayed significant neuroprotective effect and exhibited anti-inflammatory activity in a dose-dependent manner. These findings suggest that CG-A and CG-B are very important nutritional ingredients responsible for the neuroprotective and anti-inflammatory health benefits of A. tsaoko.
