Abstract

Previous studies have confirmed that KCHO-1 (Mecasin) was developed to alleviate the symptoms of Amyotrophic Lateral Sclerosis (ALS). And its toxicity test has also been carried out. The aim of this study is confirming the validation and stability of concentration analysis method of the Mecasin preparations using HPLC. As a conclusion, we found that the preparations at the concentrations of 50mg/ml and 200mg/ml in sterilized distilled water were homogeneous and it was stable for 4 hours at room temperature and 7 days refrigerated condition (2~8°C). And this method for analyzing the concentration of the Mecasin preparations has been found to be suitable. This study is helpful to promote development of reliable manufacturing medicine and good researches through definitive quality control of Mecasin as complex herbal medicine, aiming to provide help for the treatment of ALS.
