Seeds of four species of Polygonaceae were tested for lectins that precipitate human and animal serums. Rumex crispus, Polygonum convolvulus, and Polygonum pennsylvanicum developed specific precipitate bands on double diffusion on agar gel plates. These bands were enhanced and increased in number when extracts were tested against serums from patients with certain diseases. When tested against lyophilized serum, no precipitate bands developed. The active substance cannot be dialyzed through cellulose membrane against running tap water for 16 hours, and it is heat stable. Extracts from Fagopyrum esculentum developed no precipitate bands.
对蓼科四种植物的种子进行了检测，以寻找能使人类和动物血清沉淀的凝集素。皱叶酸模、卷茎蓼和宾夕法尼亚蓼在琼脂凝胶平板上的双向扩散试验中出现了特异性沉淀带。当用提取物检测某些疾病患者的血清时，这些沉淀带会增强且数量增加。当检测冻干血清时，未出现沉淀带。活性物质不能透过纤维素膜在流动的自来水中透析16小时，且具有热稳定性。荞麦的提取物未出现沉淀带。
