Abstract
The chemical composition and antioxidative activities of Platycodon grandiflorum leaves and stems was investigated in order to evaluate the potential as functional food material. The moisture contents of leaves and stems were 84.31% and 75.91%, respectively. The Ca content was the highest in leaves (351.49 mg%) and stems (217.56 mg%). The major free sugar of leaves was glucose (1,729.87 mg%) However major free sugar of stems was fructose (734.91 mg%). Glutamic acid (242.91 mg%) and arginine (228.60 mg%) in leaves were major amino acids, lysine (110.08 mg%) and glutamic acid (80.40 mg%) in stems were major amino acids. Oleic acid and linoleic acid were major fatty acids in crude fat of both leaves and stems. DPPH free radical scavenging activities of fractions from leaves and stems were rising with increasing amount of fractions. Like antioxidant activity, the reducing power of fractions from leaves and stems was also dependent on concentration while butanol fraction of stems showed the highest reducing power.
