Hello,

I must analyze tocotrienols and ferulic acid esters (oryzanol) in cereal extracts, so I look for standards for analytical method developpement, but they are not commercialised from the main firms I know (Merck, Sigma, Supelco, Fluka, Acros, ...)

I've also read some scientific articles and wrote to chemical firms that authors mentioned, but I became no answers so far...

Can anyone tell help me to find these standards or tell me if it is worth to keeping on searching, please? (if you could tell me the complete references it would be really wonderful!!)

Thank you in advance!!
