Three new quinones have been isolated from the root bark of Fijian Ventilago vitiensis. One, an isofuranonaphthoquinone, has been identified as 4,6,9-trihydroxy-3-methoxy-1-methylnaphtho[2,3-c]furan-5,8-quinone (ventilone G), whereas the other two were benzisochromanquinones, 7,10-dihydroxy-1,3-dimethyl-1H-naphtho[2,3-c]pyran-6,9-quinone (ventiloquinone L) and 7 or (8),10-dihydroxy-8 (7)-methoxy-1,3-dimethyl-1H-naphtho[2,3-c]pyran-6,9-quinone (ventiloquinone M).
