Kindly help to interpret GC-MS of plant extract?
how to relate a particular compound from the spectra. What is important point to consider?
Thank you all
Dear Vabeiryureilai Mathipi,
Two things are crucial for the identification of compounds using the GC-MS system: 1) retention time - you can compare it with standard substances if you do targeted analysis; 2) relative intensity of ions characteristic for particular compounds - it is helpful to compare it with data in the spectral library.

"Kindly help to interpret GC-MS of plant extract?"
Couple of years experience would help. Ask the GCMS expert on your lab, he/she should be able to help you.
It would probably help if you tell us how much GCMS experience you have, months, years? What else have you done with GCMS like target analysis of VOC's or SVOC's? What reference standards do you have? Do you now what Retention Indices are? Is there a GCMS expert working on your lab?

Sir Alex,
Thank you for your response. I do not have any experience on GC-MS analysis but still I have to interpret my results of GC-MS which was outsourced from other lab. I was given only spectra with many peaks on it.
What I know all about GC-MS is, it is used to detect volatile compound present in sample.
Hi,
Generally, the specific compounds to each peak are given in the spectra itself if they are already in the reference library of the GC-MS instrument you have used.
