概要

論文の詳細を見る
Moutan Cortex and Paeoniae Radix were examined for their content of paeonol by a combination of enfleurage method used in perfume industry and chromatographic technique. A very small amount of paeonol was efficiently detected by the present method without interference by coexisting foreign substances as encountered in conventional extraction methods. Addition of 4-methoxyacetophenone as an internal standard facilitated the quantitative determination of paeonol in these crude drugs. The presence of 0.025% by weight of paeonol was demonstrated by the present method in Paeoniae Radix, which was about 1/100 that in Moutan Cortex. It was also shown that the paeonol content was higher in portions near the cortex in both paeony root and Moutan Cortex.
