Meroterpenes from Peperomia oreophila Hensch. and Peperomia arifolia Miq.

摘要

One new meroterpene, 4-[(2'E)-3',7'-dimethylocta-2',6'-dien-1'-yl]-5- methyl-2-(3"-methylbut-2"-enyl)-benzene-1,3-diol, together with eight known compounds, was isolated from the MeOH extract from the leaves of Peperomia oreophila Hesch. The prenylated phenol was also isolated as main compound from the CH _2Cl _2:MeOH extract from leaves of Peperomia arifolia Miq. The structures of the substances were established on the basis of the spectral evidences and supported by literature data.
