To study the chemical constituents of Cremastra appendiculata.
The compounds were isolated by repeated column chromatography with silica gel, Sephadex LH-20 and ODS-HPLC. The structures were elucidated by analysis of spectroscopic data(1H-NMR and 13C-NMR).
Ten compounds were isolated from the EtOAc extract in the tuber of Cremastra appendiculata. Their structures were identified as shancigusin I (I), 4-O-β-D-glucopyranosyl cinnamate (II), bulbocodin D (III), blestriarene A (IV), 7-hydroxy-2,4-dimethoxy phenanthrene (V), coelonin (VI), militarine (VII), gastrodine (VIII), 3-hydroxyphenylpropionic acid (IX) and cinnamic acid (X).
Compounds I-III, IX and X are isolated from Cremastra appendiculata for the first time.
研究杜鹃兰的化学成分。
采用硅胶柱色谱、葡聚糖凝胶LH - 20柱色谱和ODS - HPLC反复柱色谱法分离化合物。通过光谱数据分析（1H - NMR和13C - NMR）阐明结构。
从杜鹃兰块茎的乙酸乙酯提取物中分离出10个化合物。它们的结构分别鉴定为山慈菇苷I（I）、4 - O - β - D - 吡喃葡萄糖基肉桂酸酯（II）、球根鸢尾定D（III）、布氏石蒜烯A（IV）、7 - 羟基 - 2,4 - 二甲氧基菲（V）、柯罗宁（VI）、米拉灵（VII）、天麻素（VIII）、3 - 羟基苯丙酸（IX）和肉桂酸（X）。
化合物I - III、IX和X首次从杜鹃兰中分离得到。
