EFFECTS OF CORIOLUS-VERSICOLOR POLYSACCHA RIDES ON PRODUCTIVITY AND LONGEVITY IN DROSOPHILA-MELANOGASTER

Coriolus versicolor polysaccharides (CVP), extracted from Coriolus ver sicolor (L) Fr, were composed of 67.53% beta-D-glucose, 12.49% D-manno se, 11.49% L-abequose, 8.21% D-galactose, and trace L-acofriose. On Or egon K stock of Drosophila melanogaster, 0.5%-5% of CVP increased the number of taking food. CVP 2%, 3%, and 5 % increased the frequency of mating and 0.5%-3% increased the number of flies in first filial gener ation (F1). CVP (2% and 3% in mated test; 1% and 2% in unmated test) p rolonged the mean lifespan, the maximal lifespan, and median lethal ti me (LT50) of flies, but not male flies.
