Abstract

An oriental drug, named NP-S, traditionally used as a therapeutic agent for hepatitis B was characterized by separating into volatile and non-volatile fractions. The volatile fraction contained ammonia as determined by ammonia kit and eight peaks when it was analyzed by gas chromatography that are not identified yet. The elemental analysis showed that the non-volatile fraction contained 15.5% carbon, 4.8% hydrogen, 11% nitrogen, and 10% sulfur along with a few trace elements such as Cl, Si, Mg and Zn. NP-S contained 6.7% peptide, 0.3% free amino acids such as Lys, Pro, Arg, lie, Tyr, Phe, His, Thr and Ser and 0.1% inorganic phosphate. The drug showed antimicrobial activity against Salmonella typhimurium, StaPhylococcus aureus and Candida albieans and also had antioxidant activity when thiobarbituric acid reacting substances(TBARS) method was applied.

본 연구에서는 간염치료제로 효과가 있는 민간제제(NS-P)의 성분 분석 및 항균 활성과 항산화 활성을 연구하였다. 이 NP-S는 그람 양성균인 Staphylococcus aureus와 그람 음성균인 Salmonella typhimurium 그리고 진균인 Candida albcans에 항균 활성을 보여 주었을 뿐만 아니라, 지질의 과산화를 억제하는 항산화 활성을 나타냈다. 이러한 NP-S는 C/H/N/S의 원소비가 15.5/4.8/11/10으로 황(S)이 상당히 많이 존재하고 있으며, 휘발성 물질인 암모니아를 2.11M 함유하고 있었다. 이 외에도 6.7의 펩타이드, 0.3의 유리 아미노산, 0.1의 무기 인산염을 함유하고 있으며, 미량 원소로서 Cl, Si, Mg, Zn도 함유하고 있다.
