Abstract: The normal hypogaeous stem of Paris polyphylla Sm.var. yunnanensis (Fr.) Hand.-Mazz. is amyloid, which contains 2.56% of polysaccharides (FP). The hypogaeous stem is converted into colloid by parasiting of Periconia Tode and other microbes, which contains 5.44% of polysaccharides (JP). The animal experiment in vivo shows that FP and JP have evident immune enhancement. These results indicate that the medical value of colloidal hypogaeous stem is the same as amyloid. They are of equal use for medicine.

摘要： 正常的滇重楼（Paris polyphylla Smith var．yunnanensis（Fr．）Hand.－Mazz．）地下茎为粉质，多糖（FP）含量 2.56％。因黑团孢霉（Periconia Tode）和其它微生物寄生，致使地下茎转化为胶质，多糖（JP）含量5.44％。FP和JP的动物体内试验表明均有显著的免疫增强作用。这些结果显示胶质地下茎的药用价值相同于粉质的，它们可等同药用。
