Dysoxylumasins A-F: Six New Limonoids from Dysoxylum mollissimum Bl.

Six new mexicanolide-type limonoids, dysoxylumasins A-F ( 1- 6), together with eight known compounds, namely litseagermacrane, 15-methoxyisodauc-3-ene-1 β,5 α-diol, isodauc-6-ene-10 β,14-diol, 4- epi-isodauc-6-ene-10 β,14-diol, 2 α,3 α,4 β-trihydroxypregnan-16-one, 1,7-phenanthrenedimethanol, spicatin, and aurantiamide, were isolated from the leaves and twigs of Dysoxylum mollissimum Bl. Their structures were established by the analyses of spectroscopic data. [ABSTRACT FROM AUTHOR]
