Figure 1. Levels of spermidine, spermine, putrescine, and L-Ornithine in whole blood (A,B), brain (C,D) and heart (E,F) after a 28-day oral spermidine supplementation using spermidine-rich plant extract in female (A,C,E) and male (B,D,F) mice (post mortem analysis). The measurements have been conducted on frozen, murine tissue samples using LC/MS-MS analysis of polyamine metabolites. Data is depicted by box plots extending from 25^th to 75^th percentile and whiskers ranging from the minimum to the maximum value. Individual data points are marked as dots. (n = 5-10 per gender and group).
