Coriolus versicolor polysaccharides (CVP), extracted from Coriolus versicolor (L) Fr, were composed of 67.53% beta-D-glucose, 12.49% D-mannose, 11.49% L-abequose, 8.21% D-galactose, and trace L-acofriose. On Oregon 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 generation (F1). CVP (2% and 3% in mated test; 1% and 2% in unmated test) prolonged the mean lifespan, the maximal lifespan, and median lethal time (LT50) of female flies, but not male flies.
云芝多糖（CVP）从云芝（Coriolus versicolor (L) Fr）中提取，由67.53%的β-D-葡萄糖、12.49%的D-甘露糖、11.49%的L-阿比可糖、8.21%的D-半乳糖和微量的L-阿可弗糖组成。在黑腹果蝇的俄勒冈K品系上，0.5%-5%的CVP增加了取食次数。2%、3%和5%的CVP增加了交配频率，0.5%-3%增加了第一代子代（F1）的果蝇数量。CVP（交配试验中为2%和3%；未交配试验中为1%和2%）延长了雌蝇的平均寿命、最大寿命和半数致死时间（LT50），但对雄蝇没有影响。
