铃兰为含有强心甙类之药用植物,很早就作为强心药物在临床上应用。我省铃兰产量甚丰,我们为了研究省内所产铃兰之强心效价,提供生产强心剂之参考,曾对铃兰之花,叶、根、叶柄、以及用铃兰制成之酊及毒甙液等的生物效价进行了实验研究。据初步实验研究结果:以叶柄含有效价最高,其次为花、根、叶与过去文献记载之根部效力最强的结果不同,其不同原因或与采集日 Lily-of-the-valley is a medicinal plant that contains strong heartworms and has long been used clinically as a cardiotonic drug. The production of lily of the province is very abundant in our province. In order to study the potency of the lily of the valley produced in the province, we provide reference for the production of cardiac stimulants. The flowers of the lily of the valley, the leaves, the roots, the petioles, and the lily of the valley The biological titer of venom broth, etc. was studied experimentally. According to a preliminary experimental study, the highest available effective price is the petiole, followed by flowers, roots, and leaves, which are different from the strongest results reported in previous literature.
