摘要
铁皮石斛(Dendrobium officinal Kimura et Migo)兼具药用价值,不仅含有人体必需氨基酸,还含有多糖、黄酮类、生物碱等活性成分,具有降血压、降血糖、抗肿瘤等功效。但石斛属植物来源众多、成分差异较大,给铁皮石斛的鉴别带来困难,利用指纹图谱技术标记特征物质可以对其鉴别及品质评价提供一定的理论依据。另外,国内外学者已从铁皮石斛中分离鉴定出多糖、黄酮类、生物碱等多种生物活性成分,证实了这些成分的药效并推断其生理作用机制。从多角度总结了近几年铁皮石斛指纹图谱、生物活性成分及作用机制的研究进展情况,以期为铁皮石斛的鉴定及药物开发研究提供一定的科学依据。
Dendrobium officinal Kimura et Migo has both high edible and medicinal value, which not only contains essential amino acids for human body, but also contains polysaccharides, flavonoids, alkaloids and other bioactive components,these ingredients can reduce blood pressure, blood sugar, anti-tumor and so on. However, it is difficult to identify Dendrobium officinal Kimura et Migo,because of its geographical origin and complex chemical components, use fingerprint technology could provide some theoretical basis to identify and evaluate Dendrobium officinal Kimura et Migo. In addition, domestic and foreign scholars had been isolated and identified polysaccharides, flavonoids, alkaloids and other bioactive components, the effect of these bioactive components was confirmed and their physiological mechanism was deduced.The relevant research on bioactive components and its function mechanism of Dendrobium officinal Kimura et Migo in recent years were summarized,in order to provide some scientific basis for identifying and drug developing of Dendrobium officinal Kimura et Migo.
