Thirteen carbazole alkaloids were isolated from Murraya euchrestifolia HAYATA (Rutaceae) collected in Taiwan. Four of them are novel carbazolequinones [murrayaquinone-A (7), -B (8), -C (9), and -D (10)], isolated for the first time from natural sources. Three of others are new alkaloids having the normal carbazole nucleus [murrayafoline-A (1), -B (2), and (+)-murrayazoline (11)]. These structures were elucidated from spectral data and chemical transformations.
从台湾采集的九里香(芸香科)中分离出 13 种
咔唑生物碱。其中四种是首次从天然来源中分离出来的新型
咔唑醌[murrayaquinone-A (7)、-B (8)、-C (9) 和-D (10)]。其他三种是具有正常
咔唑核的新
生物碱 [murrayafoline-A (1)、-B (2) 和 (+)-murrayazoline (11)]。这些结构是通过光谱数据和
化学转化来阐明的。
