Abstract:
OBJECTIVE To screen the best compatibility ratio and administration conditions of Panax ginseng -Poria cocos pair against aging ，and investigate its mechanism . METHODS P. ginseng-P. cocos pair extracts with different compatibility ratios （1∶1，1∶2，2∶1，1∶4，4∶1，m/m）were prepared ；taking Saccharomyces cerevisiae as the aging model organism ，the S. cerevisiae growth curve was drawn by MTT method ，the best compatibility ratio ，administration concentration and administration time point of P. ginseng-P. cocos pair were screened out ；the activities of antioxidant related enzymes [superoxide dismutase （SOD），peroxidase （POD），catalase（CAT）]，the levels of reactive oxygen species （ROS）and malondialdehyde （MDA），the content of adenosine triphosphate（ATP），and the mitochondrial membrane potential （MMP）in S. cerevisiae cells were detected ；mRNA expressions of SOD1，CTT1，GSH1，ATP1，MRS1 and CDC 19 were also detected . RESULTS The optimal ratio of P. ginseng-P. cocos pair for anti-aging activity was 1∶4（m/m），the optimal administration concentration was 220 μg/mL，and the optimal administration time point was the 28th hour . The extracts of P. ginseng-P. cocos pair（1∶4，m/m）could significantly increase the activities of SOD ， POD and CAT ，ATP content ，MMP，mRNA expression of CTT 1，GSH1 and MRS 1（P＜0.01），but decrease the levels of MDA and ROS ，mRNA expressions of SOD 1，ATP1 and CDC 19（P＜0.05 or P＜0.01）. CONCLUSIONS P. ginseng-P. cocos pair（1∶4， m/m）has a good anti -aging effect on S. cerevisiae ，its mechanism may be related to the positive regulation of oxidative stress and energy metabolism of S. cerevisiae cell.
