5-O-Caffeoylshikimic acid (dactylifric acid) was isolated from bracken fern as a major constituent of its acutely toxic fraction, which causes depression of leucocytes and thrombocytes in calves. 5-O-Caffeoylshikimic acid exhibited an antithiamine effect in vitro, but had no hematuric effect in guinea pigs.
5-O-Caffeoylshikimic acid(dactylifric acid)是从蕨类植物中分离出来的,是其急性毒性部分的主要成分,可导致小牛白细胞和血小板抑制。5-O-Caffeoylshikimic acid 在体外具有抗胺作用,但对豚鼠没有血尿作用。
