3,4-Di-O-caffeoylquinic acid, Isochlorogenic acid B
3,4-Dicaffeoylquinic acid (3,4-Di-O-caffeoylquinic acid), naturally isolated from Laggera alata, has antioxidative, DNA protective, neuroprotective and hepatoprotective properties. 3,4-Dicaffeoylquinic acid exerts apoptosis-mediated cytotoxicity and alpha-glucosidase inhibitory effects. 3,4-Dicaffeoylquinic acid possesses a unique mechanism of anti-influenza viral activity, that is, enhancing viral clearance by increasing TRAIL[1][2][3].
