  • Four compounds were isolated from the culture broth of Volvariella bombycina and they were identified as ergosta-4,6,8(14),22-tetraene-3-one (1), ergosterol peroxide (2), indole-3-carboxaldehyde (3), and indazole (4) by interpretation of spectroscopic data. Among them, compound 2 exhibited melanogenesis inhibitory effect in cultured B16 mouse melanoma cells.

  • Volvariella bombycinais an edible mushroom commercially cultivated in Korea and other countries. In this study, the culture characteristics and optimal growth conditions of milky mushroom strains were determined. The growth temperature and pH range of V. bombycinawas extensively investigated between 15 and 35℃ and pH 3-11. For efficient cultivation, 20 types of nutrient sources were selected, specifically, 21 carbon sources, 6 organic nitrogen sources, 7 inorganic nitrogen sources, 13 amino acids, 9 organic acids, and 13 inorganic salts. The impact of each of the selected nutrition sources and their concentration on growth was investigated. The optimum temperature and pH were determined to be 30℃ and pH 8.0, respectively. The optimum concentration of medium elements required for mycelial growth of V. bombycinawas determined to be as follows: carbon source, 0.7% Soluble starch; organic nitrogen source, 0.7% Soytone; inorganic nitrogen source, 1.0% (NH4)2C4H4O6; amino acid, 0.1% cysteine; organic acid, 0.07% lactic acid; and inorganic salt, 0.07 mM CaCl2.

  • To find antitumor components in the shake-cultured mycelia of Volvariella bombycina, the mycelia were extracted with hot water. After the extract was dialyzed and freeze-dried, a protein-polysaccharide fraction was obtained and examined for antitumor activity against the solid form of sarcoma 180 in ICR mice. It showed 60.3% inhibition ratio at a dose of 20mg/kg/day for 10 days. It was found to consist of a polysaccharide moiety and a protein moiety. After gel filtration on Sepharose 4B, Fraction B was obtained and showed the highest inhibition ratio of 71.1%. When the antitumor component was examined for immunopotentiating activity, it was found to increase the macrophage accumulation in the peritoneal cavity as well as the antibody production of the spleen cells of the mice.
