Benzoquinones from Embelia angustifolia

Phytochemistry (Oxford) 44(4): 679-681

Benzoquinones from Embelia angustifolia

Three new 2,5-dihydroxy-3-alkyl-1,4-benzoquinones, (Z)-2,5-dihydroxy-3-(pentadec-8-enyl)-1,4-benzoquinone, (Z,Z)-2,5-dihydroxy-3-(heptadeca-8,11-dienyl)-1, 4-benzoquinone and (Z)-2,5-dihydroxy-3(heptadec-8-enyl)-1,4-benzoquinone and the known 2,5-dihydroxy-3-pentadecyl-1,4-benzoquinone were isolated from the leaves of Embelia angustifolia. Their structures have been established on the basis of spectral analysis and by chemical methods.
