Abstract
|
|
|
Objectives: The purpose of this study is to investigate on storage characteristics of Herbal materials treated with Gamma-irradiation(10 KGy).
Methods: This experiments were carried out by field survey and storage characteristics were carried out by physicochemical determination.
Results: Antimicrobial activity of oriental medicine materials(Angelica dahurica Radix, Glehnia littoralis Radix) were examined, together with investigation of effects on gamma-irradiation. Oriental medicine materials contaminated in microbial cell were tend to be pinhole in packaging materials(polypropylene) by bug and Larva. At the same time, PVDC (polyvinylldichloride) package also was founded in bug and Larva by microbial contamination during storage in room temperature.
Conclusions: In conclusion, it is very desirable to dose gamma-irradiation(10 KGy) in these oriental medicine materials in order to prevent microbial activity.
