OBJECTIVE
To investigate chemical constituents from the stems of Dendrobium candidum.
METHODS
The constituents were isolated by various column chromatography methods, and their structures were elucidated by spectral analysis (IR, UV, NMR and MS).
RESULTS
Six compounds were isolated from ethanol extract and their structures were identified as 2,3,4,7-tetramethoxyphenanthrene (I), nakaharain (II), 2,5-dihydroxy-3,4-dimethoxyphenanthrene (III), confusarin (IV), nudol (V) and bulbophyllanthrin (VI).
CONCLUSION
Among these compounds, compounds II, III, VI are isolated from Dendrobium candidum for the first time.
目的
研究铁皮石斛茎的化学成分。
方法
采用多种柱色谱法分离化学成分，并通过光谱分析（红外光谱、紫外光谱、核磁共振光谱和质谱）阐明其结构。
结果
从乙醇提取物中分离出6种化合物，其结构鉴定为2,3,4,7-四甲氧基菲（I）、中井石蒜碱（II）、2,5-二羟基-3,4-二甲氧基菲（III）、混色菌素（IV）、裸茎卷瓣兰素（V）和石豆兰素（VI）。
结论
在这些化合物中，化合物II、III、VI首次从铁皮石斛中分离得到。
