3년생 의성작약품종(faeornia lacrifora Pall.)을 1994년 2월에 수확하여 유피 및 거피상태로 처리한 후 상온음건법, 화력건조법, 증건법 및 냉동건조법으로 건조방법을 각각 달리하여 주 약용성분인 paeoniflorin함량 및 일반 화학성분을 조사한 결과는 다음과 같다. 1. 건물비율 50%까지의 건조일수는 거피상태 30℃ 화력건조가 동일온도의 유피상태보다 5일이 짧으며, 거피상태에서는 50℃ 화력건조법이 1.5일로 가장 빨랐고, 121℃ 증건법은 8일로 가장 늦었다. 2. 상온음건 및 화력건조법의 경우 paeoniflorin 함량은 거피상태가 더 높았고, 반대로 증건법은 유피상태가 더 높았다. 화력건조법의 경우 건조온도가 높아짐에 따라 paeoniflorin 함량은 감소하였다. 3. 건조방법 중 30℃ 화력건조가 Paeoniflorin함량이 4.0%로 가장 높고, 건조일수가 단축되며, 색택 이 양호한 가장 적절한 건조법 이었다. 4. 화력건조시 건조온도가 높아짐에 따라 총당의 함량은 감소하고 전분은 증가하는 경향을 보였으며, 또 전분함량은 121℃ 의 증건법을 제외한 모든 건조방법에서 거피상태보다 유피상태가 더 높았다. 5. 조단백질, 조섬유 및 조회분의 함량은 유피, 거피 및 건조방법에 따라 큰 차이가 없었다. 6. Paeoniflorin과 총당의 관계는 유피상태에서 정의 유의상관이, 그리고 paeoniflorin과 전분의 관계는 거피상태에서 부의 유의상관이 있었다.
Seven different drying methods were tested in peony roots of Euisung cultivar, harvested in February, in three year's old plant. The roots were selected in length and diameter and half of the samples were removed cork-layers to compare the effects of cork-layer in processing of drying. The 30~circC heat drying without cork-layer reduced in days to drying by five days compared to those of the with cork-layers at the same temperature. The 50~circC heat drying after cork-layers removed was the most effective in days to drying. In quality of skin color of the 50~circC heating was worse to compare with the lower drying temperature. In the drying at room temperature and the heat drying at lower temperature, the paeoniflorin content in drying after cork-layers removed were higher than that of the drying with cork-layers. However, in the boiling water treatment, the paeoniflorin contents in drying after cork-layers removed were lower than those of with cork-layers. In heat drying, paeoniflorin content showed a decreasing tendency to increase of drying temperature. Total sugars in the peony roots showed a decreasing tendency according to the drying temperature increasing, but starch concentration showed a increasing tendency at the same condition. Concentrations of crude protein, crude fiber and crude ash were showed no differences in various drying methods and the materials with or without cork-layers. Relationships between the paeoniflorin and total sugars, and the paeoniflorin and starch were different significantly by the materials of cork-layers removed or not. The 30~40~circC heat drying without cork-layers was the most advisable condition for drying in paeoniflorin concentration, days to drying and skin color after drying.
