The effects of Alpinia protocatechuic acid (PCA) on spleen and liver antioxidant system in aged rats have been studied. Alpinia PCA, a phenolic compound, was first isolated from the dried fruits of Alpinia Oxyphylla Miq. in our laboratory. Young and aged rats were injected intraperitoneally with Alpinia PCA at single doses of 5 mg kg(-1) (low dose) or 10 mg kg(-1) (high dose) per day for 7 days. The activities of endogenous antioxidants and the content of lipid peroxide in spleen and liver were assayed. Compared with young group, aged rats had significantly lower splenic weights, lower activities of glutathione peroxidase (GSH-PX) and catalase (CAT), higher level of malondialdehyde (MDA) in spleen and liver. The results proved that Alpinia PCA significantly elevated the splenic weights, increased the activities of GSH-PX and CAT and decreased the MDA level of aged rats. All these suggested that Alpinia PCA was a potential anti-ageing agent, and its effects on spleen and liver were achieved at least partly by promoting endogenous antioxidant enzymatic activities and normalizing age-associated alterations. It may be therapeutically useful to minimize age-associated disorders where oxidative damage is the major cause. Copyright (C) 2011 John Wiley & Sons, Ltd.
