Abstract:A new unsaturated fatty acid monoglyceride (1), glycerol mono-(E)-8,11,12-trihydroxy-9-octadecenoate, was isolated from the seeds of Allium fistulosum L. along with five known compounds: tianshic acid (2), 4-(2-formyl-5-hydroxymethylpyrrol-1-yl) butyric acid (3), p-hydroxybenzoic acid (4), vanillic acid (5), and daucosterol (6). The structures of 1-3 were established by interpretation and full assignments of NMR spectroscopic data. Both 1 and 2 were found to inhibit the growth of Phytophtohora capsici on V8 media.
