Elaine Holmes

There are several sources including:

The BMRB database at Winsconsin

www.bmrb.wisc.edu/metabolomics/external_metab_links.shtml

The Maddison database

http://mmcd.nmrfam.wisc.edu

Back in 2011 Verpoort's group published a good article on plant-based metabolomics

http://www.cell.com/trends/biotechnology/pdf/S0167-7799(11)00031-X.pdf

They have a huge degree of knowledge on plant metabolites and would be worth contacting

Do you have mixture of compounds or purified single compound

Along with Elaine input, you can also look in HMDB. Chenomx, great option where you can do structure elucidation. You can use chenimx as free trial version from online.
