摘要
石斛为我国名贵的传统中药材,多糖是石斛属植物的主要活性成分,具有较高的药用价值。为探究铁皮石斛性质的异同及其种类,以紫秆和黄秆铁皮石斛为主要研究对象,采用红外光谱分析仪测定其红外光谱及其多糖的红外光谱。结果表明:两种铁皮石斛的波峰相似系数比较大,亲缘关系较近,而两种铁皮石斛多糖红外光谱在810cm-1处有比较显著的差异。
Dendrobium candidum is a famous traditional medicinal herbs in China .Polysaccharide is the main ac‐tive component of Dendrobium candidum .It had a high medicinal value .In order to explore the similarities and differences of Dendrobium species and its properties .Taking Dendrobium candidum with purple and yellow stem as the main objects of study ,infrared spectrum analyzer were used to determine its infrared spectrum of species and its polysaccharide .The results showed that the similarity coefficient of the same wave for the two species of Dendrobium candidum was relatively large .They have a close relationship and the infrared spectros‐copy of two species of Dendrobium candidum have a significant differences at 810 cm‐1 .
