Abstract

This study was conducted to provide basic information on the effects of drying temperatures (45, 65, and $85^{\circ}C$) on saponins and free sugar contents of a 5-year-old Platycodon grandiflorum Radix. Platycodin D levels decreased with increase in drying temperature (956, 334, and 197 mg% at 45, 65, and $85^{\circ}C$, respectively). Polygalacin D levels were the highest at $45^{\circ}C$ (577 mg%), while platycodin $D_3$ and deapioplatycodin D were high at $65^{\circ}C$ (304 and 272 mg%, respectively). Sucrose levels were 3,825 mg% at $85^{\circ}C$ and 1,226 mg% at $45^{\circ}C$, and decreased when the drying temperature was decreased. The sucrose content showed significant negative correlation with saponin levels in dried P. grandiflorum ($-0.987^{**}$, p<0.01). These results suggested that drying P. grandiflorum at low temperatures is more economically viable.
