Plant growth regulators (PGRs) and PAs had a significant effect on in vitro plant regeneration and also a biochemical accumulation of flavonols, hydroxybenzoic and hydroxycinnamic acid derivatives in C. anguria. Due to these metabolic variations, the antioxidant and antibacterial activities were increased with in vitro regenerated plants than in vivo plants. This is the first report describing the production of phenolic compounds and biological activities from in vitro and in vivo regenerated plants of C. anguria.
