Ethanolic and hexane extracts from the aerial parts of Juniperus lucayana were assayed against the phytopathogenic fungus Botrytis cinérea by the poisoned food technique. The hexane extract showed to have a higher antifungal activity than ethanolic extract. Fractionation of hexane extract by silica gel open column chromatography and HPLC afforded seven known compounds sandaracopimaric acid (1), 4-epi-dehydroabietic acid (2), oplopanone (3), oplodiol (4), nephtediol (5), 7α-hydroxycallitrisic acid (6), and 7-oxocallitrisic acid (7). Compound 1 showed a significative fungal growth inhibition during the assay. The effect of compounds 2-7 on spore germination fungus was also studied.
