Abstract

This study was conducted to provide basic information about the drying methods (daylight, hot-air, and freeze drying) used for Platycodon grandiflorum radix. We investigated the mineral, free sugar, and saponin contents of dried P. grandiflorum. The potassium and calcium contents of hot-air-dried samples were the highest (22.6 and 9.2 mg%, respectively), when compared to those of daylight- or freeze-dried samples. Glucose and sucrose contents were the highest in freeze-dried samples (1,552 and 145.0 mg%, respectively), while fructose content was the highest in hot-air-dried samples (611.9 mg%). Platycodin D content was the highest in hot-air-dried samples (622.0 mg%); however platycodin D3, polygalacin D, and deapioplatycodin D contents were the highest in daylight-dried plant (113.5, 756.6, and 109.2 mg%, respectively). Glucose content was highly negatively correlated (p<0.01) with platycodin D, platycodin D3, and deapioplatycodin D (-0.924, -0.957, -0.861, p<0.01, respectively). These results suggest that the drying method affects the saponin content of P. grandiflorum and daylight and hot-air drying methods are more suitable and beneficial than freeze-drying.

도라지 건조방법에 대한 기본 정보를 제공하고자 일광건조, 열풍건조 그리고 동결건조를 실시하여 무기성분과 환원당 그리고 사포닌 함량을 조사한 결과를 요약하면 아래와 같다. 칼륨과 칼슘은 각각 22.6과 9.2 mg%로 열풍건조에서 높게 나타났다. Platycodin D는 열풍건조에서 622.0mg%로 가장 높게 나타났으며, platycodin D3, Polygalacin D, deapioplatycodin D는 일광건조에서 각각 113.5, 756.6, 109.2 mg%로 나타났다. Glucose와 platycodin D, platycodin D3, deapioplatycodin D의 함량간의 상관계수는 각각 -0.924, -0.957, -0.861로 고도의 음의 상관을 보였다(p<0.01). 동결건조가 다른 건조조건에 비해 색이 밝게 나타났다. 이상의 결과로 도라지의 건조 방법은 일광건조와 열풍건조가 동결건조보다 좋은 것으로 평가 되었지만 일광건조는 건조기간이 길어 많은 노동력이 소요된다. 따라서 열을 가하여 건조하면서 건조기간도 줄이고 도라지 약리성도 높이기 위한 적정 건조 온도에 관한 연구도 수행 되어야 할 것으로 사료된다.
