Difference in Contents of Chemical Components in Radix of Paeonia lactiflora Pall. with Root Diameters

작약(芍藥)의 뿌리굵기에 따른 성분함량(成分含量) 차이(差異)

This experiment was conducted to know the relationship between root diameter and the contents of paeoniflorin and some Chemical components in Paeoniae radix. Paeoniae radix of Euisung cultivar was harvested on 17 June, 1993 and divided into four gorups according to root diameter such as $30{\pm}2mm,\;17{\pm}1mm,\;12{\pm}1mm\;and\;7{\pm}1mm$. Paeoniflorin, total sugars, starch, crude protein, crude fat and crude ash of them were analyzed after dryed them for 30 days in room temperature. The ratio of shrinkage with different root diameter were not different significantly, and the average ratio of them was about 30%. Contents of paeoniflorin of $17{\pm}1mm$ root diameter was lower than that of $7{\pm}1mm$. but contents of total sugar and starch of $17{\pm}1mm$ were higher than those of $7{\pm}1mm$. Paeoniflorin contents was positively correlated with crude protein and crude fiber, and crude protein contents was negatively correlated with total sugars and starch.

재배(栽培) 작약(芍藥) 정식(定植) 4년차(年次)인 의성품종(Paeonia lactiflora Pall.)을 지상부(地上部) 생육(生育)이 가장 왕성(旺盛)한 시기(時期)인 6월(月)에 채굴하여 뿌리굵기에 따라 $30{\pm}2mm,\;17{\pm}1mm,\;12{\pm}1mm,\;7{\pm}1mm$로 구분(區分)하여 일반화학성분(一般化學成分)과 주(主) 약효성분(藥效成分)인 paeoniflorin 함양(含量)을 조사(調査)한 결과(結果)는 다음과 같다. 1. 작약근(芍藥根)의 건조(乾燥) 후(後) 수축율(收縮率)은 약(約) 30%이며. 뿌리의 굵기에 따라 그 차이(差異)가 인정(認定)되지 않았다. 2. 외관상(外觀狀) 우수(優秀) 생약재(生藥材)로 평가(評價)되는 $17{\pm}1mm$ 굵기는 $7{\pm}1mm$굵기에 비해 paeoniflorin의 함양(含量)은 1.0% 낮으나 총당(總糖) 및 전분(澱粉)의 함양(含量)은 8%, 5%가 각각(各各) 많았다. 3. Paeoniflorin 함양(含量)은 조단백질(粗蛋白質) 및 조섬유(粗纖維) 함양(含量)과 정(正)의 유의상관(有意相關)을 나타내었고, 조단백질(粗蛋白質)의 함양(含量)은 총당(總糖) 및 전분(澱粉)과 부(負)의 유의상관(有意相關)을 나타내었다.
