Simulated Drought and Salinity Modulates the Production of Phytochemicals in Acalypha wilkesiana

Abstract

In this study, 3-month old Acalypha wilkesiana plants grown from stem cuttings were exposed to simulated drought and salinity separately to assess the effects of such abiotic factors on the phytochemical production level in this plant. Preliminary study, based on the qualitative analysis, showed the presence of alkaloids, cardial glycosides, flavonoids, saponins, steroids, and tannins in A. wilkesiana leaves. Results of the quantitative analysis showed that plants under drought and salinity stresses produce lower quantity of alkaloids, flavonoids, and tannins while saponin production was increased.
