The results showed that seven ingredients were detected in portal vein plasma after oral administration of 16.3 or 8.15 g/kg equivalent of raw material of Wuzhuyu-tang extract. The absorption rate of limonin, evodiamine, gingerol （6-Gi）, and ginsenoside-Rg1 was greater than that of isorhamnetin-3-O-β-D-glucosyl （6″→1″′）-α-L-rhamnoside, ginsenoside-Rb1 （Rb1）, and ginsenoside-Re （Re）. The time most elements were absorbed into the blood was 30 to 60 minutes after administration. Re, 6-Gi and Rb1 were metabolized faster. The results suggest that the seven ingredients described above are the active components for treating migraines.展开更多

To some degree, antioxidants may provide beneficial effects on neuronal damage induced by seizures. However, the protective effects of Momordica charantia polysaccharides (MCPs) on seizures remain unclear. In this study, our purpose was to investigate the effects of MCPs on oxidative stress and neurodegeneration in an experimental Kainic acid (KA)-induced rat seizure model. MCPs treatments decreased the level of malondialdehyde (MDA) and increased the activities of superoxide dismutase (SOD) and catalase (CAT) in the hippocampus of the KA-induced animal model. Moreover, MCPs significantly attenuated KA-induced neuronal loss in the CA1 and CA3 hippocampal regions. Based on these results, MCPs exert neuroprotective effects by attenuating KA-induced neuronal damage in the brain through their free radical scavenging activities.展开更多
