Abstract Reptanthrin and isoreptanthrin, two new dimeric phenanthrenes, were isolated from the orchid Bulbophyllum reptans which also afforded nine known stilbenoids, viz. gymnopusin ( 1a ) [2,7-dihydroxy-3,4,9-trimethoxyphenanthrene], confusarin ( 1c ) [2,7-dihydroxy-3,4,8-trimethoxyphenanthrene], 2,7-dihydroxy-3,4,6-trimethoxyphenanthrene ( 1d ) and its 9,10-dihydro derivative, flavanthrinin ( 1e
摘要 Reptanthrin 和isoreptanthrin,两个新的二聚菲,是从兰花Bulbophyllum reptans 中分离出来的,它也提供了九种已知的芪类化合物,即。裸露菌素 (1a) [2,7-二羟基-3,4,9-三甲氧基菲], 混淆素 (1c) [2,7-二羟基-3,4,8-三甲氧基菲], 2,7-二羟基-3,4, 6-三甲氧基菲 (1d) 及其 9,10-二氢衍生物, 黄烷酮 (1e) [2,7-二羟基-4-甲氧基菲] 及其 9,10-二氢衍生物 (coelonin), 3,3'-二羟基-5 -甲氧基联苄基 (batatasin-III)、cirrhopetalanthrin (2a) [2,2',7,7'-tetrahydroxy-4,4'-dimethoxy-1,1'-biphenanthyl] 及其 9,9',10,10' -四氢衍生物(黄芪)。reptanthrin
