The development of complementary and/or alternative drugs for treatment of hepatitis C virus (HCV) infection is still needed. Antiviral compounds in medicinal plants are potentially good targets to study. Morinda citrifolia is a common plant distributed widely in Indo-Pacific region; its fruits and leaves are food sources and are also used as a treatment in traditional medicine. In this study, using a HCV cell culture system, it was demonstrated that a methanol extract, its n-hexane, and ethyl acetate fractions from M. citrifolia leaves possess anti-HCV activities with 50%-inhibitory concentrations (IC(50)) of 20.6, 6.1, and 6.6 μg/mL, respectively. Bioactivity-guided purification and structural analysis led to isolation and identification of pheophorbide a, the major catabolite of chlorophyll a, as an anti-HCV compound present in the extracts (IC(50) = 0.3 μg/mL). It was also found that pyropheophorbide a possesses anti-HCV activity (IC(50) = 0.2 μg/mL). The 50%-cytotoxic concentrations (CC(50)) of pheophorbide a and pyropheophorbide a were 10.0 and 7.2 μg/mL, respectively, their selectivity indexes being 33 and 36, respectively. On the other hand, chlorophyll a, sodium copper chlorophyllin, and pheophytin a barely, or only marginally, exhibited anti-HCV activities. Time-of-addition analysis revealed that pheophorbide a and pyropheophorbide a act at both entry and the post-entry steps. The present results suggest that pheophorbide a and its related compounds would be good candidates for seed compounds for developing antivirals against HCV.

Several recent scientific articles have found a direct correlation between Glutathione levels and viral activity for hepatitis B and C. When viral load increases, Glutathione decreases. Researchers from Germany report that adding NAC (N-acetyl cysteine) to HBV producing cells lines can reduce hepatitis viral load 50 fold. Glutathione is used by the liver to help break down toxins. Patients who have chronic infection for more than 90 days should ask their physicians to check their Glutathione levels. A test kit is available from ImmunoSciences Labs; contact information is included. An amino acid, L-Glutamine, can be used with Alpha Lipoic Acid and NAC to increase Glutathione levels. Chlorophyll also offers benefits to people with hepatitis and other infections. Instructions on how to use a special retention enema containing chlorophyll, water, and apple cider vinegar are provided.
