Abstrakt: To improve the stability and broaden the application of resveratrol (Res), the Res conjugated linoleate (RCL) were synthesized successfully using Res and 9c,11t-conjugated linoleic acid (CLA) with N, N'-carbonyldiimidazole (CDI) as catalyst for the first time. The Res conversion and the yield of RCL were achieved at 96.85% and 65.30%, respectively. In comparison with Res, RCL has lower acid value (1.80 mg/g) and peroxide value (3.25 meq/kg) and higher thermal stability (improved by 115.3 ℃). RCL was identified as a novel triester compound with a physical appearance as a light-yellow viscous oil. The 9c,11t-CLA was activated by CDI first, reacted with Res to form 4'-Res-ester preferentially, followed by 5,4'-Res-ester and 3,5,4'-Res-ester. The transition-state quaternary ring structures of monoesters were the key structures determining the formation of RCL. This study provided an efficient and eco-friendly approach for the synthesis of RCL, promoting the development of the synthesis of Res long-chain fatty acid ester.
