Chromenes of polyketide origin from Peperomia villipetiola

The extracts of leaves and stems of Peperomia villipetiola have been found to contain myristicin and seven chromenes (1-7) of orsellinic acid-type. The anti-fungal activities of the chromenes measured by bioautography against Cladosporium cladosporioides and Cladosporium sphaerospermum indicated compounds 6 and 7 as the most active.
