TI  - Triacylglycerol composition of walnut (Juglans regia L.) cultivars: 
      characterization by HPLC-ELSD and chemometrics.
PG  - 7964-9
AB  - A total of 26 walnut (Juglans regia L.) samples from 9 cultivars (Arco, 
      Franquette, Hartley, Lara, Marbot, Mayette, Mellanaise, Parisienne, and Rego) 
      harvested in the 2001, 2002, and 2003 crop years and grown in two geographical 
      origins (Braganca and Coimbra, Portugal) were evaluated with regard to their 
      triacylglycerol composition. The methodology employed was reversed-phase 
      high-performance liquid chromatography coupled to an evaporative light-scattering 
      detector (RP-HPLC-ELSD) after extraction of the lipidic fraction of the nuts. 
      Nine compounds were separated, identified, and quantified. All samples presented 
      an identical qualitative profile composed by LLnLn, LLLn, LLL, OLLn, OLL, PLL, 
      OOL, and PLO (P = palmitoyl; O = oleoyl; L = linoleoyl; Ln = linonenoyl). 
      Trilinolein (LLL) was the major triglyceride, followed by 
      dilinoeoyl-oleoyl-glycerol (OLL) and dilinoleoyl-linolenoyl-glycerol (LLLn), with 
      mean values of 37.7, 18.5, and 18.4%, respectively. Significant differences in 
      composition were found between cultivars, and these differences were also 
      significant when cultivars were grouped by year of production, showing that 
      besides genetic factors, the triacylglycerol composition can be strongly 
      influenced by environmental factors.
