Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Four novel <italic>γ</italic>‐pyrone (=4<italic>H</italic>‐pyran‐4‐one) metabolites, petrorhagiosides A–D, along with four known analogs, have been isolated from the MeOH extract of <italic>Petrorhagia saxifraga</italic>, 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.</p> </abstract>
