[#2013-12] Maitake Su, Chun-Han et al Inhibitory potential of Grifola frondosa
This study has demonstrated that the nonpolar fraction of GF possesses potent anti-a-glucosidase activity, and its inhibitory kinetics is competitive inhibition. It was as good as acarbose in inhibiting starch digestion in vitro. This study also suggests that oleic acid and linoleic acid could be the major active compounds of GF contributing to the potent anti-a-glucosidase activity

The hypoglycemic effect of an α-glucan (designated here as MT-α-glucan) from the fruit body of the Maitake medicinal mushroom, Grifola frondosa, on a murine type 2 diabetes mellitus (T2DM) model was evaluated. Body weight and levels of fasting plasma glucose, glycosylated hemoglobin, triglycerides, cholesterol, free fatty acid, nitric oxide (NO), NO synthase, inducible NO synthase, and hepatic malondialdehyde content decreased significantly when MT-α-glucan was administered to T2DM mice. The content of serum insulin, hepatic glycogen, and...

Because of a dismal prognosis for advanced renal-cell carcinoma (RCC), an alternative therapeutic approach, using vitamin K3 (VK3) and D-fraction (DF) was investigated. VK3 is a synthetic VK derivative and DF is a bioactive mushroom extract, and they have been shown to have antitumor activity. We examined if the combination of VK3 and DF would exhibit the improved anticancer effect on RCC in vitro. Materials and Methods: Human RCC, ACHN cell line, were treated with varying concentrations of VK3, DF, or a combination of the two. Cell viability...

Hericium erinaceus, as a commonly used medicine or food, has attracted much attention due to its health effects when used as a home remedy for some diseases. The aim of this work was to investigate the hypoglycemic and hypolipidemic effects of aqueous extract of Hericium erinaceus (AEHE) in streptozotocin (STZ)-induced diabetic rats. Methods: Diabetes was induced in Wistar rats by the administration of STZ (55 mg/kg BW.) intraperitoneally. AEHE (100 and 200 mg/kg BW.) was administered for a period of 28 days. The effects of AEHE on glucose,...

Agaricus brasiliensis has been demonstrated to have potent antitumor activity. The activity is postulated to act through mediation of the host immune system. We have reported that A. brasiliensis extract (ABE) inhibited compound 48/80 induced a systemic anaphylaxis-like reaction, ear swelling response, and passive cutaneous anaphylaxis-like reaction in mice. There is some recent information available on the mechanism of antiallergic effects resulting from oral administration of ABE. However, information regarding how ABE may activate...

The agaricoglyceride is anew fungal secondary metabolite that constitutes esters of chlorinated 4-hydroxy benzoic acid and glycerol. The objective of this study was to explore whether the administration of agaricoglyceride could correct hepatic glycemic metabolism dysfunction by attenuating inflammation in the liver. The effects of agaricoglycerides on tumor necrosis factor-α, interleukin-1β, vascular endothelial growth factor-α, interleukin-17, insulin secretion, adiponectin, leptin, hepatic glycogen, nuclear factor-κB activation, and...

Agaricus brasiliensis currently is one of the most studied fungi because of its nutritional and therapeutic properties as an anti-inflammatory agent and an adjuvant in cancer chemotherapy. The effects of orally administered aqueous A. brasiliensis extract (14.3- and 42.9-mg doses) on parenchymal lung damage induced by carcinogenic 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) were observed in Wistar rats. NNK treatment induced pulmonary inflammation, but not lung cancer, in the rats. The lungs of animals treated with NNK showed a higher...

The Royal Sun medicinal mushroom, Agaricus brasiliensis, is used as a natural health product. In Japan, however, the quality control of some of these mushroom products has been viewed as a safety problem. Focusing on the quality control of A. brasiliensis KA21, we have performed several safety studies. To date, we have established evidence that this mushroom can be used safely as an immunostimulant and to mediate biochemical parameters associated with obesity or diabetes. Furthermore, to improve the manufacturing process of this mushroom, we...

Although the medicinal mushroom Hericium erinaceus is used extensively in traditional Chinese medicine to treat chronic superficial gastritis, the underlining pharmaceutical mechanism is yet to be fully understood. In this study, minimum inhibitory concentration (MIC) values of extracts prepared from the fruiting bodies of 14 mushroom species (H. erinaceus, Ganoderma lucidum, Cordyceps militaris, Pleurotus eryngii, P. ostreatus, Agrocybe aegerita, Lentinus edodes, Agaricus brasiliensis, A. bisporus, Coprinus comatus, Grifola frondosa,...

It is already known that the Maitake (D-Fraction) mushroom is involved in stimulating the immune system and activating certain cells that attack cancer, including macrophages, T-cells, and natural killer cells. According to the U.S. National Cancer Institute, polysaccharide complexes present in Maitake mushrooms appear to have significant anticancer activity. However, the exact molecular mechanism of the Maitake antitumoral effect is still unclear. Previously, we have reported that Maitake (D-Fraction) induces apoptosis in breast cancer cells...
