8-hydroxyguanosine (8-OHG) is a marker for measuring the rate of oxidative damage to nucleic acids and lipids.The concentration of 8-OHG in CSF in Parkinson's disease (PD) patients is approximately three-fold that in controls. The concentration of 8-OHG in CSF decreased significantly with the duration of disease. However, the concentration of 8-OHG in serum was not significantly altered in PD patients compared to that in controls.

3,5-Di-O-caffeoylquinic acid methyl ester exhibits potent inhibitory activities against the formation of advanced glycation end products (AGEs); it exhibits cytotoxicity actions against human cervix carcinoma HeLa cells. 3,5-Di-O-caffeoylquinic acid methyl ester shows high efficiency and low toxicity with antivirus activity against RSV.
