Note: control and LSPC represent different intervention groups, respectively. PDB, ECG, EGC, HVA, 3,4-DHPA, p-HPPA, PCC, 3-HPAA, and 3-HBA stand for procyanidin dimer B, epicatechin gallate, epigallocatechin, homovanillic acid, 3,4-dihydroxyphenylacetic acid, 3-(4-hydroxyphenyl)propionic acid, protocatechuic acid, 3-hydroxyphenylacetic acid, and 3-hydroxybenzoic acid, respectively. Values represent the concentrations of metabolites in different rat tissues, and they were all presented as the means ± SEM (); ND = not detected; , , indicates significant differences between two groups with or without LSPC (, , and ), respectively.
