Chemical fingerprinting and the biological properties of extracts from Fomitopsis pinicola

Abstract

This study investigated the in vitro antioxidant and anticancer properties of the Fomitopsis pinicola extract (EMFP). The antioxidant activity of EFMP was analysed via free radical scavenging (DPPH, ABTS and Hydroxyl radicals) assay and a protein oxidation assay. EFMP effectively scavenged free radicals and exhibited remarkable protection against protein oxidation. The proliferation of EMFP-treated HepG2 cells was remarkably decreased. EMFP effectively increased the reactive oxygen species (ROS) production, depleted the mitochondrial membrane potential (MMP) and promoted the apoptosis of HepG2 cells. In addition, EMFP increased the malondialdehyde (MDA) content and reduced the activities of SOD, CAT and GPx in HepG2 cells. Using UPLC-Triple-TOF-MS, 2 phenolic compounds and 14 triterpenes were identified. These compounds may be the primary contributors to the antioxidant and anticancer capacities of EMFP. Together, these findings highlight the possibility of exploiting EMFP for its desired pharmaceutical ingredients.
