铁筷子药材是提取强心甙的重要资源,然而人们对其中所含脂类的研究却很不足,近年苏联制药业的方法是用沸点为40～70℃的石油醚萃取粉碎的干燥的根和根茎,随后完全去除溶剂。从《阿布哈兹铁筷子(Helleborus abchasicus)铁筷子根和根茎中提取出18％的中性油脂,它是一种稠状棕黄色液体,有微弱特殊气味,密度0.900～0.965,折射指数1.450～1.480,酸值120～180,从中可分离出 Iron chopsticks medicine is an important resource for the extraction of heart palpitations. However, the research on lipids contained in it is very inadequate. In recent years, the Soviet Union’s pharmaceutical industry has used the method of extracting crushed dry roots with petroleum ether with a boiling point of 40-70°C. Rootstock, then completely remove the solvent. Eighteen percent of the neutral oil was extracted from the roots and rhizomes of Helleborus abchasicus. It is a thick, brownish-yellow liquid with a faint and special odor, with a density of 0.900 to 0.965 and a refractive index of 1.450. 1.480, with an acid value of 120-180, can be separated from
