Background: Medicinal plants are potential sources for drug candidates. It possesses with various metabolites which have many pharmacology effects. Ruta angustifolia is one of medicinal plants that has been used traditionally for liver disease. Previous study it has been demonstrated to inhibit hepatitis C virus under in vitro cell culture. It decreased protein NS3 level and gave synergistic effect in combination with simeprevir and telaprevir. This plant provides a prospective candidate to develop as anti-HCV Objective: This study evaluates the phytochemistry screening for qualitative assay and determine the concentration of rutin as marker compound for developing R. angustifolia extract as anti-HCV agent. Materials and Methods: R. angustifolia leaves were extracted with 70\% of ethanol. Extract and rutin were analysis their anti-HCV activity by in vitro culture cells of Huh7it. The concentration of rutin was determine by TLC densitometry. Results: The 70\% ethanol extract of R. angustifolia dan rutin exhibit anti-HCV activities with IC50 value of 2.9 {\textpm} 0.8 μg/ml and 28.1 {\textpm} 5.6 μg/ml, respectively. Screening phytochemistry demonstrated to contain flavonoid, terpenoid, alkaloid and polyphenols. TLC densitometry analysis yield the concentration of rutin in extract 0.06 \%. Conclusion: Extract of 70\% ethanol of R. angustifolia has a potential anti-HCV activity. Extract of R. angustifolia may provide a good candidate for developing anti-HCV agents.

Introduction: Hepatitis C Virus (HCV) is a major health problem, which infects approximately 170 million people among worldwide population. Moreover, there is no vaccine available to prevent HCV infection and the current anti-HCV drugs have not covered all the various genotypes and subtypes. Meanwhile, medicinal plants have been widely used to treat a variety of infectious disease. Our previous study reported that ethanol extract of Melicope latifolia has been shown to exert anti-HCV activity towards a number of different virus genotypes with mainly inhibition mechanism at the entry step. Further separation was needed to purify and identify the active anti-HCV constituent using bioactivity-guided isolation method. Materials and Methods: In vitro Anti-HCV assay was performed using hepatocyte cell line (Huh7it) and HCV genotype 2a (JFH1). The purification of M. latifolia ethanol extract (B1F) was done by liquid-liquid fractionation, vacuum liquid chromatography (VLC), and high-performance liquid chromatography (HPLC). The active fraction was further identified by thin layer chromatography (TLC) and the major constituent was determined by nuclear magnetic resonance (NMR) spectra data analysis. Results: The fractionation of M. latifolia leaves ethanol extract resulted an alkaloid fraction (B1F D2H.3) containing a major constituent N-methylflindersine. This alkaloid fraction was active to reduce HCV JFH1 with an inhibition concentration (IC50) value of 6.21 {\textmu}g/mL, a cytotoxicity concentration (CC50) value of 82.64 {\textmu}g/mL, and a selectivity index value of 13.31. Conclusion: An alkaloid fraction of M. latifolia (B1F D2H.3) was known to have major compound named N-methylflindersine. This alkaloid fraction exhibited strong anti-HCV against JFH1 in vitro. The results indicated that this alkaloid fraction may a good candidate for anti-HCV agent.

Background: Hepatitis B virus (HBV) infects more than 300 million people globally and is a common cause of liver cancer. Current therapy using reverse transcriptase inhibitors require long-term treatment and the potential risk of development of drug-resistant viruses remains an important issue to be considered. Hence, the development of new drugs is critical. Traditional medicinal plants used for the treatment of infectious diseases may provide a viable option for the discovery of anti-HBV drug candidates. Objective: This study examined anti-HBV activity of 31 kinds of Indonesian plants. Materials and Methods: Crude extracts of various part of plants, leaves and stem, were obtained using dichloromethane and ethanol solvent. The effect on viral entry was examined by determining levels of HBsAg expression in the supernatants of HBV-infected HepG2-NTCP cells by ELISA. The effect on HBV replication was determined by measuring HBV DNAs amounts in Hep38.7-Tet cells by quantitative real-time PCR. Results: The extracts of Phyllantus niruri leaves and Curcuma xanthorrhiza showed reduction of strong HBsAg production from HepG2-NTCP cells with IC50 values of 170.48 and 270.51 μg/mL, respectively. Treatment of HepAD38.7-Tet cells with P. niruri and C. xanthorhiza at the highest concentration while avoiding cytotoxicity reduced extracellular HBV DNA levels by 70\% and 30 \% of the untreated control respectively. Conclusion: P. niruri inhibited both the entry and HBV replication, thus P. niruri is a promising candidate for anti-HBV drug development.
