Yamabushitake, or Hericium erinaceum, is an edible mushroom fungus belonging to Aphyllophorales, Hydnaceae (Hericiaceae), Hericium. It grows widely in Japan and the whole of China. In recent years, Hericium erinaceum fungus has been cultivated by wood-log culture (Photo. 1) or culture-bed methods such as bottleculture and bag-culture. Several newly isolated compounds from this mushroom have shown interesting biological activities such as cytotoxic effects on HeLa cells,

promotion of the synthesis of neuro-growth factor, and inhibition of pollen tube germination, and moreover the fruiting body of Hericium erinaceum, or its liquid-cultured mycelia, or an alcohol-precipitated fraction of its culture filtrate showed antitumor activities based on immunopotentiation. 1- 5) Previoulsy, we have reported some antitumor polysaccharides obtained from several fungi belonging to Polyporaceae and Agaricaceae. 6 - 8) In this note, we describe the evaluation of antitumor activities of the polysaccharides fractionated from the fruiting bodies of yamabushitake mushroom.

Note: In four-week old female ICR/Slc mice, 6 x 106 cells/mouse of 7-day-old Sarcoma 180 from an ascites tumor were implanted subcutaneously in the right groin and 10 mg/kg of fraction from Flo were injected i.p. once daily for 10 consecutive days starting 24 hours after tumor implantation. The tumor size was measured at 28 days after tumor implantation. The survival time and mortality were measured 61 days after tumor implantation.

Gel filtration by using a Toyopearl HW-65 column. Modified Lowry method. Phenol-sulfuric acid colorimetry. Each polysaccharide was hydrolyzed with 0.5 to 1.0 M sulfuric acid at 100°C for 3 to 6 hours and the hydrolyzate thus obtained was treated by ppc. Further, its alditol acetate derivative was identified and measured by GC method with the use of a Shimadzu GC-4CM -PF apparatus. KBr tablet method by using JIR-RFX-3001 apparatus of Nippon Bunko.

Fruiting bodies of the fresh mushroom were extracted stepwisely with 85% ethanol (30°C, 24 hr), hot water (lOO°C, 3 hr), 1% ammonium oxalate (100°C, 5 hr), and 5% sodium hydroxide (30°C, 12-24 hr) as described previously.6) The hot water extract (FI), 1% ammonium oxalate extract (FII), and 5% sodium hydroxide extract (FIll), were further fractionated by DEAE-cellulose chromatography, Toyopearl HW65F gel filtration, and Con A-AF-Toyopear1650 affinity chromatography. Finally, five· antitumor-active polysacchride fractions were obtained. Table I shows the evaluation of the antitumor activities of the yamabushitake polysaccharides obtained during the fractionation and purification steps. Table II shows the physicochemical properties of the active polysaccharide fractions. FI o-a-f3 (an unadsorbed fraction from Con A-AF-Toyopearl 650 affinity column was a heteroglycan containing mainly xylose, glucose, and mannose and FIo-a-1X (an adsorbed fraction) was a xylan-protein complex, and both of them had f3-(l--t3) and (1--t6) glucan chains in those molecules based on the IR and NMR spectra (Table III). These f3-glucan parts of the molecules may be significant in the expression of antitumor activities. FII-I showed a good antitumor effect (Table I). FII-I was a glucoxylan having f3-(1--t3) and (l--t6) glucosidic linkages that gave characteristic spctra in lH_ and 13C-NMR (Table III). The spectrometric data were as follows: IR I' max (KBr): 893cm- 1. lH-NMR spectrum b: 4.88,4.74, 4.51, 4.25 ppm. 13C-NMR spectrum b: 108.1,91.0,81.3,78.3,74.9,74.0, 69.0, 65.8 ppm. FIII-2b was a galactoxyloglucan-protein complex and showed antitumor activity. This fraction was prepared from alkali-solubilized FIll by fractional precipitation with acetic acid followed by gel filtration on Toyopearl HW-65F. The structure of the FIII-2b was analyzed with the solid state 13C-NMR, which showed a characteristic spectrum of f3(l--t3) and (1--t6)-glucosidic linkages whose peaks (ppm) appeared at 4.50 and 4.25 (anomeric proton); 104.2 (C-l), 87.5 (C-3), 75.2 (C-5),
