Yes. You can look on conditions in which the plant maximize the production of selected msetabolites. Sometimes even presence of other plant or organisms mear the plant can enhance it.

If you are looking for enhancement of biological activity of a particular metabolite the nanotechnology can be helpful.

I think you can enhance the activity of plant extracts when you prepare it as Nano-particles especially as Anti-cancer by inject the casualty part

Yes, some authours have reported that biological activities of nanoparticles synthesised from plant extract were enhanced when the activities were compared with that of the plant extract

Increasing surface area can enhance better engagement in a heterogeneous reaction. Therefore, biological activities of extracts are expected to be higher with nanoparticles.
