Abstract

Abstract Ginsenoside Rk1 (G-Rk1) is one of the unique components created by processing ginseng at high temperature, in particular of Sun Ginseng (SG). The aim of our study was to systematically review the pharmacological effects of G-Rk1.we conducted our search in eight databases and searched manually to select in vivo and in vitro original studies that provided information about biological pharmaceutical effects of G-Rk1 and were published up to August 2015 with no restriction in language or study design. We retrieved 21 eligible papers out of 121 identified ones. Some studies confirmed the G-Rk1 anticancer effects by investigating “cell viability”, “cell proliferation inhibition”, “apoptotic activity”, “anticancer activity” and “effects of G-Rk1 on G1 phase and autophagy in tumor cells” either alone or in combination with G-Rg5. Others proved that it has anti-platelet aggregation activities and anti-inflammatory effects, enhances cognitive function, reduces lipid accumulation and prevents osteoporosis. In conclusion, G-Rk1 has a significant anti-tumor effect of liver cancer, melanoma, and gastric cancer. Additionally, G-Rk1 has demonstrated as anti-platelet aggregation, anti-inflammatory, and anti-lipid accumulation. All these results corroborate the clinical effects of G-Rk1 and demonstrate the potential possibility to develop G-Rk1-based treatments, either alone or in combination with G-Rg5, with previously mentioned conditions.
