Objectives: Samul-tang is commonly used to alleviate the side effects of chemotherapy. This study aimed to establish an efficient method of extracting ACTS002 based on Samul-tang using the yield, high-performance liquid chromatography (HPLC), and antioxidant assay. Methods: ACTS002 was extracted from each extraction solvent, and the contents of 5-hydroxymethyl-2-furaldehyde (5-HMF), paeoniflorin, and ferulic acid were quantitatively analyzed and compared using HPLC. Moreover, the antioxidant activities of ACTS002 were measured using total flavonoids, total phenolic compounds, 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), and Ferric reducing/antioxidant power (FRAP). Results: All of the components were set as the index contents because they were easy to process. The antioxidant activity of total flavonoids was the highest in 70% ethyl alcohol extracts, and total phenolic compounds were the highest in 50% ethyl alcohol extracts. In DPPH, 50% ethyl alcohol extracts showed the highest activity, and in ABTS 70% ethyl alcohol extracts were the highest. In FRAP, 70% ethyl alcohol extracts showed the highest activity. Conclusions: ACTS002 can control quality by setting 5-HMF, paeoniflorin, and ferulic acid as the index contents. The antioxidant activity measurement was relatively high in the 50% and 70% ethyl alcohol extracts. Our results can predict the possibility of a pharmacological activity and the standardization of ACTS002.

Hwangryunhaedok-tang (HT) is prescribed in oriental medicine to treat inflammation-related diseases. This study examined the anti-bacterial effect to select the index components of Traditional Chinese Medicine (TCM) HT. The disc diffusion method and minimum inhibition concentrations (MIC) tests were conducted to measure the antibacterial activity of HT. The strains were Staphylococcus aureus ATCC 25923 and Escherichia coli 23724. Berberine and geniposide were selected as the index components of HT and were analyzed quantitatively by high-performance liquid chromatography (HPLC). As a result, the inhibition ring was formed at $11.7{\pm}1.3mm$ and $8.7{\pm}0.7mm$ at HT 20 mg and 10 mg on S.aureus ATCC 25923, respectively; and $8.0{\pm}0.0mm$ at HT 20 mg on E.coli ATCC 23724. The MIC were 31.25 mg/mL in S.aureus ATCC 25923 and 125.0 mg/mL in E.coli ATCC 23724. In quantitative analysis for standardization, HT contained 16.55 mg/g of berberine and 81.85 mg/g of geniposide. Overall, when antibiotics are developed using natural products, they may reduce the side effects and inhibit resistant bacteria. If research on HT continuously proceeds, positive developments are expected to be made in oriental medicine as well as in various other industries. 황련해독탕은 한방산업에서 염증관련 질환에 다빈도로 사용되는 처방이다. 본 연구의 목적은 전통적 한약인 황련해독탕의 항균활성을 확인하고 지표성분을 선정하는 것이다. 황련해독탕의 항균활성을 측정하기 위하여 디스크 확산법과 최소억제농도법을 사용하였다. 사용균주는 Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 23724였으며 대조군으로 oxacillin과 ciprofloxacin을 이용하여 황련해독탕의 항균활성을 확인하였다. 결과적으로 디스크 확산법에서는 S.aureus ATCC 25923에서 황련해독탕 20 mg과 10 mg은 $11.7{\pm}1.3mm$, $8.7{\pm}0.7mm$의 억제환을 형성하였으며 E.coli ATCC 23724에서는 황련해독탕 20 mg이 $8.0{\pm}0.0mm$의 억제환을 형성하였다. 최소억제농도는 S.aureus ATCC 25923가 31.25 mg/mL, E.coli ATCC 23724 에서는 125.0 mg/mL였다. 표준화를 위한 HPLC 정량분석 결과, 황련해독탕은 berberine을 16.55 mg/g 함유하고 있었으며 geniposide를 81.85 mg/g 함유하고 있었다. 천연물을 이용하여 항생제를 개발할 경우에는 내성세균을 억제하고 부작용을 줄일 수 있다는 장점이 있다. 이러한 점을 착안하여 지속적으로 연구를 진행한다면 한방산업과 더불어 여러 산업에서의 발전을 기대할 수 있을 것이다.
