직약 건조시 양질의 약재를 생산하기 위한 기초자료를 얻고자 뿌리굵기에 따라 박피정도를 달리하여 시험한 결과를 요약하면 다음과 같다. 1 작약의 뿌리는 굵기별로 건조하는 것이 건조시간 단축효과가 있었는데, 기계박피시 적정건조 시간은
This experiment was carried out to gather basic information for improvement of peeling methods in peony (Paeonia lactiflora) roots which have been used for medicinal resources in Korea. Drying time required was shortened in thin root. Optimum drying time after machine peeling appeared to be 20 hrs in 5 to 10mm of root diameter, 39 hrs in 10 to 15mm, 48 hrs in 15 to 20mm, 56 hrs in more than 20mm, but those of unpeeled roots took 11 hrs in 5mm of root diameter and 4 hrs in exposed parent material. Paeoniflorin content in dried roots after peeling was lower than that of unpeeled root. Paeoniflorin content in root below 5mm in diameter was highest (6.15 %) and that was decreased in the increased root diameter up to 20mm, but it was slightly increased in root greater than 20mm in diameter.
