Dr Dukes database has lots of info but was abandoned for some time. I notice that recently it began to be updated again. https://phytochem.nal.usda.gov/phytochem/search

Dear Dr. Mathavan Muthaiyan, please see the following links:

I used this recently and it was useful "Dr. Duke's Phytochemical and Ethnobotanical Databases"

I agree with Jacob Simons

Please find my database done in UK

NAPRALERT (NATURAL PRODUCT ALERT),

To date more than 200,000 scientific papers and reviews are included in NAPRALERT, representing organisms from all countries of the world, including marine and microorganisms. We believe that coverage of the literature is comprehensive from at least 1975.

Please check the following sites IMPPAT: Indian Medicinal Plants, Phytochemistry And Therapeutics

a curated database

Dr. Duke's Phytochemical and Ethnobotanical Databases

KNApSAcK: A Comprehensive Species-Metabolite Relationship Database(http://kanaya.naist.jp/KNApSAcK/)

You can search phytochemicals in FooDB database also.

i suggested following article. which consist all data (open access)

Dr. Dukes database is a better option. Still the database is flodded with informations like flavonoids, ash and so on... which are too general. It is not much specific as I expected while I tried to use it. Hence I used this database as well as I did literature reviews to find phytochemical from plants.

I think that Dr. Dukes database is a better source.
