Abstract Diosindigo A, diosindigoB and biramentaceone have been isolated fromheartwood of Diospyrosmelanoxylon . A violet pigment isolated from the same source has been shown to be a new pentacyclicquinone. Sunlight causes diosindigoB to change to the pentacyclicquinone and biramentaceone. The intense peaks at m/e 389 and 388 in the mass spectrum of diosindigoB are doublets which arise by fragmentation
摘要 从Diospyros melanoxylon 的心材中分离得到薯蓣A、薯蓣B 和biramentaceone。从同一来源分离的紫罗兰色素已被证明是一种新的五环醌。阳光导致diosindigo B 变成五环醌和biramentaceone。diosindigo B 质谱中 m/e 389 和 388 处的强峰是双峰,由 M + 和 M + + 2 裂解产生。
