中文摘要：

采用多种色谱分离技术首次从石豆兰属植物芳香石豆兰中分离了13个化合物,这些化合物经波谱方法鉴定为：moscatin（1）,3,7-dihydroxy-2,4-dimethoxyphenanthrene（2）,2,7-dihydroxy-3,4-dimethoxyphenanthrene（3）,2,5-dihydroxy-4-methoxy-9,10-dihydrophenanthrene（4）,ephemeranthol-A（5）,3,7-dihydroxy-2,4-dimethoxy-9,10-dihydrophenanthrene（6）,2,4-dihydroxy-7-methoxy-9,10-dihydrophenanthrene（7）,coelonin（8）,rotundatin（9）,4＇,5-dihydroxyl-3,3＇-dimethoxybibenzyl（10）,moscatilin（11）,batatasinⅢ（12）,tristin（13）.其中化合物5,6,7和9首次从石豆兰属植物中分离得到.

英文摘要：

The chemical constituents of BulbophyUum ambrosia were studied and 13 compounds were isolated by the method of silica gel and Sephadex LH-20 column chromatography. Their structures were identified as moscatin （ 1 ）, 3,7-dihydroxy- 2,4-dimethoxyphenanthrene （ 2）, 2,7-dihydroxy- 3,4-dimethoxy-phenanthrene （ 3 ）, 2,5 -dihydroxy-4-methoxy-9,10-dihydrophenanthrene （ 4 ）, ephemeranthol-A （ 5 ）, 3,7 -dihydroxy -2,4 -dimethoxy-9,10-dihydrophenanthrene （ 6）, 2,4-dihydroxy-7-methoxy-9,10-dihydrophenanthrene （ 7）, coe- lonin （8）, rotundatin （9）, 4＇, 5 - dihydroxyl - 3,3＇ - dimethoxybibenzyl （10）, moscatilin （ 11 ）, batatasin Ⅲ （12） ,and tristin （13） on the basis of spectral analysis.Among them,compounds 5,6,7 and 9 were isolated from Bulbophyllum for the first time.
