强心作用，铁筷子醇提取物能使在位和离体蛙心停跳于收缩期，对猫心电图的影响也类似于洋地黄，起效较迅速。铁筷子醇提义务兵强心作用的生物效价；鸽单位69.16+/-1.8mg/kg；猫单位50.36+/-3.4mg/kg；豚鼠单位64.49+/-3.4mg/kg。与已研究过的国产强心植物比较，猫单位介于福寿草和械柳皮之间，较圆蒴黄麻、长蒴黄麻、夹竹桃叶、海果、神速寿草为弱；较黄花竹桃叶、械柳皮为强。忆证明其强心作用的有效成分为铁筷子甙(去葡萄糖嚏根草甙desglucohellebrin)，其安全范围与毒毛花苷G、地高辛相似。加工炮制 采收加工
The positive inotropic effect of Hellebrin extract from Adonis coerulea can cause the frog heart to stop beating during both in vivo and in vitro systole. Its effect on cat electrocardiograms is similar to that of digitalis, and it takes effect relatively quickly. The biological potency of Hellebrin extract in terms of positive inotropic effect is as follows: 69.16+/-1.8mg/kg in pigeons, 50.36+/-3.4mg/kg in cats, and 64.49+/-3.4mg/kg in guinea pigs. When compared with domestically studied cardiac plants, the potency in cats falls between Adonis amurensis and Stellera chamaejasme, and is weaker than Adonis amurensis, Stellera chamaejasme, Nerium oleander leaves, Gelsemium elegans, and Adonis vernalis, but stronger than Nerium oleander leaves and Stellera chamaejasme. It has been demonstrated that the effective component of its positive inotropic effect is Hellebrin glycoside (desglucohellebrin), and its safety range is similar to that of ouabain and digoxin. Processing and preparation involve harvesting and processing.
