Reversed phase liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (RP-HPLC/MS-APCI) was used to identify and quantify triacylglycerols (TAGs) having odd-numbered ω-phenylalkanoic acids from seeds of the flower plant Dracunculus vulgaris, and TAGs from the bacterium Rhodococcus erythropolis prepared by precursor directed biosynthesis from phenylalanine and having the corresponding even-numbered ω-phenylalkanoic acids. Model compounds, which are not commercially available, were prepared by organic synthesis and this allowed us to extend the number of identified natural TAGs to nearly 140 molecular species. Both synthetic and natural compounds containing ω-phenylalkanoic acids were found to have antioxidant and free radical scavenging properties.
反相液相色谱-大气压化学电离质谱法（RP-HPLC/MS-APCI）用于鉴定和定量来自花科植物龙舌兰属植物种子中的具有奇数ω-苯烷酸的三酰基甘油（TAG），以及通过苯丙氨酸前体定向生物合成并具有相应偶数ω-苯烷酸的红球菌 Rhodococcus erythropolis 中的 TAG。通过有机合成制备了模型化合物，这些化合物没有商业用途，这使我们能够将鉴定的天然 TAG 数量扩展到近 140 种分子种类。含有ω-苯烷酸的合成和天然化合物均具有抗氧化和自由基清除特性。
