Background : This study was conducted to serve as a basis for the production of high quality organic cultivation Platycodin grandiflorum Ridix roots by analyzing the content of saponins according to organic fertilizer for organic farming. Methods and Results : Platycodin grandiflorum Ridix was treated by with biodegradable film, rice husks, and sawdust, non-mulching (hand weeding). A root of Platycodon grandiflorum were analyzed saponins using HPLC harvested on October. Content of Plantycodin D3 was an average of 68.5 ㎎/100g, which appeared as 111.2 ㎎/100g highest content in the sawdust treated. Deapioplatycodin D showed the highest 48.1 ㎎/100g in the sawdust treated. The content of Platycodin D was shown to 246.2∼373.8 ㎎/100g, the highest values were observed in non-mulching, it showed the lowest value in the rice husks treated. The content of Polygalacin D showed up to 156.0 ㎎/100g in the non-mulching as the biggest difference, the lowest value were 30.1 and 32.2 ㎎/100g in sawdust and rice husks treated. Large differences between fertilizers was not showed, but the overall saponin content of Platycodin grandiflorum Ridix were low in value compared to the control than organic fertilizers. Conclusion : Large differences between mulching materials was showed, thus the overall saponin content of Platycodin grandiflorum Ridix was highest in value compared to non-mulching than sawdust treatment. Mulching Platycodin grandiflorum Ridix with sawdust was an effective method for improving saponin contents.
