一、强心甙的来源和结构常用强心甙都来源于植物。最早期应用的强心甙就是洋地黄叶中的成分,故强心甙统称为洋地黄类药物。实际上含强心甙的植物种类很多。甙又叫作苷,旧名叫配糖体。甙是糖和非糖化合物缩合而成的,所以水解后可产生糖和非糖化合物。非糖化合物又称为甙元或配糖基(图1)。 First, the source and structure of cardiac glycosides commonly used cardiac glycosides are derived from plants. The earliest application of cardiac glycosides is the composition of digitalis leaves, so cardiac glycosides collectively referred to as digitalis drugs. In fact, many kinds of plants with cardiac glycosides. Glycosides, also known as glycosides, the old name is glycosylated. Glycosides are the condensation of sugar and non-sugar compounds, so the hydrolysis can produce sugar and non-sugar compounds. Non-sugar compounds also known as glycosides or glycosides (Figure 1).
