Mubarak Ameen certainly proposes the 'state of the art' solution to profiling your extracts. In my experience, all the terpenoid groups mentioned in your question are detectable by this means. Although acidic compounds are often less so.
However, if you do not have access to GC-MS you can use TLC. Not all monoterpenes are as volatile as, say, menthol. Often the irregular monoterpenoid group known as iridoids form glycoside conjugates which are certainly not volatile. A useful reference in this regard would be Wagner & Bladt (1996) Plant Drug Analysis - A Thin Layer Chromatography Atlas, 2nd ed., Berlin: Springer.
Thanks so much for the assistance, i have both GC-MS and TLC results both the library gave results that are not so helpful. I will check the atlas that Philip Kerr suggested , thank you.
Can someone assist me with reliable methods to assay quantitatively anti-nutrictive substances in green vegetables.
Also, i need the best fractionation solvents for dichloromethane, ethyl acetate and methano,l the extraction was done successively. Thank you
@ Mahmoud.
Thanks for the suggestion, i will do just that.
How do i evaluate anti-nutritive agents such as cyanide, oxalates etc from leafy vegetables and their flowers?
