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
四种新型γ吡喃酮(= 4 ħ -2H-吡喃-4-酮)的代谢物,petrorhagiosides A-d,具有四个已知类似物沿,已从的甲醇提取物中分离Petrorhagia虎耳草,多年生草本植物典型的地中海植被。新化合物的结构是在广泛的光谱分析基础上建立的,包括1D- 2D-NMR(1 H,1 H-DQ-COSY,TOCSY,HSQC,CIGAR-HMBC和HSQC-TOCSY)实验。
