Abstract
An active glucoside that enhanced release of histamine from rat peritoneal mast cells was isolated from a toxic fraction of bracken fern, Pteridium aquilinum, by partition column chromatography on Sephadex G-25. It was a yellowish amorphous powder on freeze-drying, readily soluble in water or ethanol, and insoluble in ether. It was hydrolysed with beta-glucosidase to release D-glucose. It was assumed to be a kind of beta-glucopyranoside with a carbocyclic structure in the aglycone moiety.
摘要
从蕨菜（Pteridium aquilinum）的有毒部分通过葡聚糖凝胶G - 25分配柱色谱法分离出一种能增强大鼠腹膜肥大细胞组胺释放的活性糖苷。冻干后它是一种淡黄色无定形粉末，易溶于水或乙醇，不溶于乙醚。它用β - 葡萄糖苷酶水解可释放出D - 葡萄糖。推测它是一种在苷元部分具有碳环结构的β - 吡喃葡萄糖苷。
