  Lolium multiflorum seeds were tested by MALDI TOF-TOF MS using 3 extraction solvents (NaCL neutral, NaCl acid, propanol). Our aim is to develop a method for grass seed testing. Among the 3 methods, only the propanol extraction agent was able to obtain a noise-free spectrum, revealing the m/z values of the reserve protein in the italian ryegrass seed.
