As an edible sclerotia-forming fungus, Poria cocos is widely used as a food supplement and as a tonic in China. High-performance liquid chromatography-quadrupole/time-of-flight mass spectrometry (HPLC-QTOF-MS/MS) was applied to identify triterpene acids in fermented mycelia of P. cocos, as well as the epidermis and inner part of natural sclerotia. A total of 19 triterpene acids were identified in fermented mycelia, whereas 31 were identified in the epidermis and 24 in the inner part. Nine triterpene acids were quantitatively determined, and the concentrations of two valuable triterpenes, dehydropachymic acid and pachymic acid, reached 1.07 mg/g and 0.61 mg/g in the fermented mycelia part, respectively, and were both significantly higher than the concentration in the two natural parts. The fermented mycelia could be a good choice for producing some target triterpene compounds and functional foods through fermentation thanks to the high concentration of some triterpene acids.

This study investigated the potential effects of dehydroeburicoic acid (TT), a triterpenoid compound from Antrodia camphorata, in vitro and examined the effects and mechanisms of TT on glucose and lipid homeostasis in high-fat-diet (HFD)-fed mice. The in vitro study examined the effects of a MeOH crude extract (CruE) of A. camphorata and Antcin K (AnK; the main constituent of fruiting body of this mushroom) on membrane glucose transporter 4 (GLUT4) and phospho-Akt in C2C12 myoblasts cells. The in vitro study demonstrated that treatment with CruE, AnK and TT increased the membrane levels of glucose transporter 4 (GLUT4) and phospho-Akt at different concentrations. The animal experiments were performed for 12 weeks. Diabetic mice were randomly divided into six groups after 8 weeks of HFD-induction and treated with daily oral gavage doses of TT (at three dose levels), fenofibrate (Feno) (at 0.25 g/kg body weight), metformin (Metf) (at 0.3 g/kg body weight) or vehicle for another 4 weeks while on an HFD diet. HFD-fed mice exhibited increased blood glucose levels. TT treatment dramatically lowered blood glucose levels by 34.2%~43.4%, which was comparable to the antidiabetic agent-Metf (36.5%). TT-treated mice reduced the HFD-induced hyperglycemia, hypertriglyceridemia, hyperinsulinemia, hyperleptinemia, and hypercholesterolemia. Membrane levels of GLUT4 were significantly higher in CruE-treated groups in vitro. Skeletal muscle membrane levels of GLUT4 were significantly higher in TT-treated mice. These groups of mice also displayed lower mRNA levels of glucose-6-phosphatase (G6 Pase), an inhibitor of hepatic glucose production. The combination of these agents produced a net hypoglycemic effect in TT-treated mice. TT treatment enhanced the expressions of hepatic and skeletal muscle AMP-activated protein kinase (AMPK) phosphorylation in mice. TT-treated mice exhibited enhanced expression of hepatic fatty acid oxidation enzymes, including peroxisome proliferator-activated receptor α (PPARα) and increased mRNA levels of carnitine palmitoyl transferase Ia (CPT-1a). These mice also exhibited decreased expression levels of lipogenic fatty acid synthase (FAS) in liver and adipose tissue and reduced mRNA levels of hepatic adipocyte fatty acid binding protein 2 (aP2) and glycerol-3-phosphate acyltransferase (GPAT). These alterations resulted in a reduction in fat stores within the liver and lower triglyceride levels in blood. Our results demonstrate that TT is an excellent therapeutic approach for the treatment of type 2 diabetes and hypertriglyceridemia.

The hepatoprotective effects of eburicoic acid (TR1) and dehydroeburicoic acid (TR2) from Antrodia camphorata (AC) against carbon tetrachloride (CCl4)-induced liver damage were investigated in mice. TR1 and TR2 was administered intraperitoneally (i.p.) for 7 days prior to the administration of CCl4. Pretreatment with TR1 and TR2 prevented the elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and liver lipid peroxides in CCl4-treated mice. The activities of antioxidant enzymes [catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx)], nitric oxide (NO) production, and tumour necrosis factor-alpha (TNF-α) were decreased after the treatment with TR1 and TR2 in CCl4-treated mice. Western blotting revealed that TR1 and TR2 significantly decreased inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expressions and increased the expression of cytochrome P4502E1 (CYP2E1) in CCl4-treated mice. Therefore, we speculate that TR1 and TR2 protect the liver from CCl4-induced hepatic damage via antioxidant and anti-inflammatory mechanisms.
