To compare the chemical compositions between Dendrobium candidum (D. candidum) and Dendrobium nobile (D. nobile).
Relative area and content of every chromatographic peak in the ammonic chloroform extracts of D. candidum were compared with those of D. nobile with high performance liquid chromatography-mass spectrometry.
The relative area of alkaloids accounted for 2.34% and 41.87% in D. candidum and D. nobile, respectively. The relative area of 25 identical compositions took up 97.12% in the total area of D. candidum and 50.09% in that of D. nobile, and contents of 23 composition were higher in D. candidum than those in D. nobile.
The quantity and contents of alkaloids are remarkably different between D. candidum and D. nobile. However, D. candidum has a higher quality than D. nobile in terms of the same chemical compositions.
比较铁皮石斛与金钗石斛的化学成分。
采用高效液相色谱 - 质谱联用技术，比较铁皮石斛氨性氯仿提取物与金钗石斛中各色谱峰的相对面积和含量。
生物碱的相对面积在铁皮石斛和金钗石斛中分别占2.34%和41.87%。25种相同成分的相对面积在铁皮石斛总面积中占97.12%，在金钗石斛中占50.09%，且铁皮石斛中23种成分的含量高于金钗石斛。
铁皮石斛与金钗石斛中生物碱的数量和含量存在显著差异。然而，就相同化学成分而言，铁皮石斛的品质高于金钗石斛。
