The effect of antioxidant activity of Platycodon grandiflorum (PG) on the liposomal phospholipid membrane was investigated by spectrophotometry. Membrane oxidation causes damage to the membrane fluidity and permeability. It brings further destruction to the sustenance of biological homeostasis. In addition, it is related to several diseases, aging and carcinogenesis. The sample PG was extracted and fractionated to five different types; butanol (PGMB), ethylacetate (PGMEA), ethylether (PGMEE), hexane (PGMH) and methanol (PGMM). The oxidation indices of PGMEA and PGMEE fractions in oxidized dilinoleoylphosphatidylcholine (DLPC) liposomes had stronger antioxidant activities than that of ${\alpha}$-tocopherol and were similar to antioxidant activities compared with butylated hydroxy toluene (BHT), a well-known potent antioxidant, in oxidized DLPC liposomes. The oxidation indices of PGMM extract, PGMB and PGMH fractions exhibited weak antioxidant activity compared with ${\alpha}$-tocopherol in oxidized DLPC liposomes. The oxidation indiex of PGMEE fractions added with vitamin C showed even strong antioxidant activity in the oxidized DLPC liposomes. The oxidation activity of BHT with vitamin C also proved to be stronger than BHT without vitamin C. Therefore vitamin C evidently helps to improve the effect of antioxidant in DLPC liposomes. These results indicate that potentially bioactive substances in PGMEE fraction has a function as potent antioxidant against phospholipid membrane oxidation.
