Abstract

|
Objectives : This study was carried out to evaluate the quality of different drying methods and different roots(primary root and lateral root) of Angelica gigas Nakai.
Methods : The experimental method was performed according to the Korea Pharmacopoea Eleventh edition (KP11). Loss on drying, ash, acid insoluble ash, ethanol extract, nodakenin and total decursin contents were tested to evaluate the quality of root tissue of Angelica gigas Nakai. In addition, the treatment of different root parts were prepared in two groups of washing dry process and natural dry process.
Results : In comparison of dry processing methods, total contents of nodakenin and total decursin in the primary root and lateral root through washing dry process were ranged from 3.55 to 4.09% and from 5.18 to 6.13%, respectively. And also, those of roots from the natural dry process were from 4.36 to 6.22% and from 6.28 to 8.34%, respectively. In the washing dry process and natural dry process methods, 47.9% and 22.3% higher amount of nodakenin and total decursin were measured in lateral root compared to primary root. In common, lateral roots accumulated higher contents of nodakenin and total decursin compared to primary roots, and samples drying processed with natural dry process compared to washing dry process method contained higher amount of compounds.
Conclusions : We sincerely hope that this study will be contributed to the standardization and quality control of Angelica Gigas Root.
