Hi I'm doing a project on natural products and I'm wondering if somewhere there is at least an estimated number of how many exist?

If this exists somewhere can you please provide a reference.

Please and Thank you! :)

  • $\begingroup$ What I would do is to search for the capacity of the largest database for the natural products fulfilling your definition of them. For instance, here is an outdated (2015) review covering databases from the structural data to some ancient Chinese recipes. On average, there is probably about 50000 or so chemical substances characterized (I might be entirely wrong, not my field). $\endgroup$ – andselisk Jan 5 '19 at 14:31

    $\begingroup$ @Bianca this article gives the number of known natural products and tries to provide an estimate of the number of possible ones (though keep in mind Ivan's point about the definition of product). They come up with a value on the order of 50 million. ncbi.nlm.nih.gov/pmc/articles/PMC3447393 $\endgroup$ – Tyberius Jan 5 '19 at 15:52
