Four novel γ-pyrone (=4H-pyran-4-one) metabolites, petrorhagiosides A-D, along with four known analogs, have been isolated from the MeOH extract of Petrorhagia saxifraga, a perennial herbaceous plant typical of Mediterranean vegetation. The structures of the new compounds were established on the basis of extensive spectroscopic analyses including 1D- an 2D-NMR (1H, 1H-DQ-COSY, TOCSY, HSQC, CIGAR-HMBC, and HSQC-TOCSY) experiments.

Abstract
Four novel γ-pyrone (=4H-pyran-4-one) metabolites, petrorhagiosides A-D, along with four known analogs, have been isolated from the MeOH extract of Petrorhagia saxifraga, a perennial herbaceous plant typical of Mediterranean vegetation. The structures of the new compounds were established on the basis of extensive spectroscopic analyses including 1D- an 2D-NMR (1H, 1H-DQ-COSY, TOCSY, HSQC, CIGAR-HMBC, and HSQC-TOCSY) experiments.
