Abstract Cirrhopetalidin and cirrhopetalinin, two new bibenzyl derivatives, and 3,3′-dihydroxy-5-methoxybibenzyl (batatasin-III) were isolated from the orchid Cirrhopetalum andersonii . The structures of the new bibenzyls were established as 2′,3-dihydroxy-3′-methoxy-4,5-methylenedioxybibenzyl and 3,3′-dihydroxy-4,5-methylenedioxy-bibenzyl, mainly from spectral evidence.
摘要 从兰花Cirrhopetalum andersonii 中分离得到了Cirrhopetalidin 和cirrhopetalinin 这两种新的联苄衍生物和3,3'-二羟基-5-甲氧基联苄(batatasin-III)。新联苄的结构确定为 2',3-二羟基-3'-甲氧基-4,5-亚甲二氧基联苄和 3,3'-二羟基-4,5-亚甲二氧基-联苄,主要来自光谱证据。
