暗黄层孔菌提取物的制备:标本干燥后被粉碎为末,用10%NaOH溶液在沸水浴中提取,过滤后,按滤液体积加三倍量乙醇沉淀,沉淀经透析后再用三倍量乙醇沉淀,所得的沉淀经蒸发干燥即得提取物。暗黄层孔菌提取物的抗肿瘤活性:能延长皮下移植腹水型肝癌小鼠的生存期限。对皮下移植的腹水型肉瘤180和腹水型肝癌都显示一定的抑制作用。
The preparation of the extract of Phellinus vermiculari: the specimens are dried and then crushed to the end, and extracted with a 10% NaOH solution in a boiling water bath. After filtration, the volume of the filtrate is tripled by the amount of ethanol. The precipitate is dialyzed and then used three times. A quantity of ethanol is precipitated and the resulting precipitate is evaporated to dryness to obtain the extract. The anti-tumor activity of the extract of Phellinus linteus: it can prolong the life span of subcutaneously transplanted ascites liver cancer mice. Ascites sarcoma 180 and ascites liver cancer showed some inhibitory effects on subcutaneous transplantation.
