Studies on Antitumor Components of Flammulina velutipes of Korea (I)
Woo, Myoung-Sik ;
The Korean Journal of Mycology, volume 11, issue 2, 1983, Pages 69~77
To find antitumor components with low toxicity in the Basidiomycetes of Korea, the carpophores of Flammulina velutipes (Fr.) Singer were extracted with hot water for eight hours. The extract was purified by dialyzing through Visking tube and a protein-bound polysaccharide fraction was obtained as pale brownish amorphous powder after freeze-drying. The fraction was examined for antitumor activity against sarcoma 180 implanted subcutaneously in the left groin in ICR mice. The inhibition ratio of this fraction against the tumor was 62.3% at the dose of 10mg/kg/day for the period of ten days. The tumors in three of the ten treated mice were completely regressed. The chemical analysis of the antitumor component by anthrone and Lowry-Folin methods showed that it consisted of a polysaccharide (42.4%) and a protein (24.5%). The hydrolysis of the polysaccharide moiety with 3% HCl-MeOH and trimethysilylation of the hydrolyzate yielded five monosaccharides which were identified by G.L.C. Several amino acids were identified by an amino acid autoanalyzer in the acid hydrolyzate of the protein moiety.
Physiological and Ecological Studies on Mycelia of Armillariella mellea

The Korean Journal of Mycology, volume 11, issue 2, 1983, Pages 79~84
To study physiological and ecological characters of the secondary mycelia of Armillariella mellea, it was cultivated on the various media. It was grown very well on the malt extract medium compared with its growth on yeast extract medium, potato dextrose medium and Hamada medium. The temperature of
gave the best condition for it to grow. The highest rate of growth was shown in medium of pH 6. Heteroauxin of 5 ppm concentration showed a increase as 26.2% in growth in compared with the control group. Gibberelline 10ppm, Tomatoton of 10,000 dilution and Adoton of 5,000 dilution showed positive effect. It was shown that the use of above hormones in appropriate concentration brought the effect of growth, but overuse of them brought inhibitory effect. Under the same condition of 200ppm concentration, vitamin A gave the highest growth of 18.2% than that of the control used.
Studies on the Components of Sarcodon aspratus(I)
Park, Wan-Hee ;
The Korean Journal of Mycology, volume 11, issue 2, 1983, Pages 85~89
The aims of this study were to investigate various components and their physiological activities of Sarcodon aspratus (Berk.) S. Ito which grows wildly in Korea, belonging to the family Thelephoraceae. The analysis of the powered carpophore of this fungus by TLC and an amino acid autoanalyzer revealed that it contained twenty-one free amino acids and that twentytwo total amino acids were identified in its acid hydrolysate. These amino acids were also quantified.

To investigate antitumor constituents of Hydnum repandum, which belongs to edible basidiomycetes, the mycelia separated from the carpophore were shake-cultured and subjected to hot water extraction. The extract was concentrated under vacuum and mixed with a three-fold volume of 95% ethanol to yield precipitates. The water soluble fraction of the precipitates was dialyzed and then lyophilized to yield a water soluble protein-polysaccharide fraction (= WPPF). This exerted antitumor activity against sarcoma 180 implanted in ICR mice. When administered i.p. at the dose level of 20mg/kg once daily for ten consecutive days, it showed an inhibition ratio of 54.3%. WPPF was found to be composed of a polysaccharide moiety (42% of WPPF) and a protein moiety (28% of WPPF) when determined by colorimetric method using anthrone reagent and Folin's phenol reagent. The polysaccharide moiety of WPPF was found to contain glucose (57.4%), mannose(19.3%), galactose (10.8%), xylose (6.8%), and fucose (5.7%), when the methanolysate of WPPF was analysed by GLC method.
Studies on Constituents of Higher Fungi of Korea(XL) - A Sterol of Phallus impudicus -
Choi, Eung-Chil ; Chung, Kyeong-Soo ; Kim, Jong-Chan ; Kim, Byong-kak ;
The Korean Journal of Mycology, volume 11, issue 2, 1983, Pages 97~98
The carpophores of Phallus impudicus collected at Gal-mae-ri in Gyeong-gi Province were subjected to chemical analysis for sterol constituents. The dried carpophores were homogenized and extracted with chloroform-methanol(2 : 1). After saponification of the dried extract, unsaponified components were obtained by ether extraction of the reaction mixture. A sterol fraction was separated by preparative TLC and from this fraction, ergosterol was identified by gaschromatographic analysis with authentic sterols.
Yield Loss Associated with Disease Severity of Soybean Black Root Rot by Cylindrocladium crotalariae
Sung, Jae-Mo ; Chung, Kil-Woong ;
The Korean Journal of Mycology, volume 11, issue 2, 1983, Pages 99~101
Black root rot caused by Cylindrocladium crotalariae is one of the most serious soilborne disease in soybean. Plant height reduction of Hwangkeum Kong was 38% by the rotting of the whole main root and 9% by rotting of the half of the main root as compared with partial discoloration in the main root. Pod number per plant and seed weight were significantly reduced by the increase of the disease severity. Important yield components such as number of pods per plant and seed weight were negatively correlated with the soybean black root rot severity.
