효소분해와 HPLC를 이용한 황산콘드로이틴나트륨의 정량

Determination of Sodium Chondroitin Sulfate by Enzymatic Digestion and HPLC

혼합물 중에서 미량 존재하는 황산콘드로이틴나트륨을 정량하기 위하여, Chondroitinase ABC를 사용하여 효소반응을 시킨 후 얻어지는 ${\Delta}Di-6S$(2-acetamido-2-deoxy-3-0-(${\beta}$-D-gluluco-4-enepyranosyluronic acid)-6-0-sulf-D-galactose)를 지표성분을 설정하여 고성능 액체크로마토그래피(HPLC)를 이용하는 방법을 확립하였다. 230nm에서 흡광도를 측정하였고, 검출한계는 $1{\mu}g/ml$였다. 본 분석법을 재제에 적용하였을 때 캅셀제는 $100.01{\pm}1.58%$, 점안제는 $99.89{\pm}1.80%$로 재현성이 있는 결과를 나타내었다.

In order to determine sodium chondroitin sulfate in the mixture, chondroitinase ABC was used for enzymatic reaction. The procedure was rapid, simple, quantitative and the HPLC analysis of ${\Delta}Di-6S$(2-actamido-2-deoxy-3-0-(${\beta}$-D-gluco-4-enepyranosyluronic acid)-6-0-sulfo-D-galactose) in the sodium chondroitin sulfate was obtained. The absorbance was measured at 230nm and detection limit was $1{\mu}g/ml$. When we applied this method to the drugs(capsule, opthalmic solution), it gave the mean contents of $100.01{\pm}1.58%$ and $99.89{\pm}1.80%$ respectively.
