继续我们对Murraya异国情调Linn的研究。(S. M. paniculata),我们报道了莫西汀1(1),木抑菌素七甲基醚,2咔唑生物碱,莫拉唑啉,马哈宁比滨和吉利比宁3,我们现在报道了一种新的抗生素二聚体香豆素的结构,名为香豆素(2),其具有异常的环己烯体系类似于环双亚二茂铁4 [Thamnosin 5(3)]。
Abstract A new trioxygenated C-8 prenylated coumarin, 5,6,7-trimethoxy-8-(2′,3′-dihydroxyisopentenyl)-coumarin and the laevorotatory form of mexoticin, sibiricin and phebalosin were isolated from the leaves of Murrayagleinei together with the coumarins meranzin hydrate, meranzin, murralongin, murrangatin and scopoletin, the flavone exoticin, the alkaloid skimianine and the sterol stigmasterol.
In continuation of our studies on MurrayaexoticaLinn. (Syn. M. paniculata) from which we reported mexoticin1 (1), hibiscetin heptamethyl ether,2 carbazole alkaloids, murrayazoline, mahanimbine and girinimbine,3 we now report the structure of a newantibiotic dimeric coumarin named mexolide (2) having an unusual cyclohexene system similar to that in cyclobissuberodiene4 [thamnosin5 (3)].
