Drought stress is one of the most significant abiotic factors that limit plant growth and survival. However, drought stress treatment can increase the synthesis of plant bioactive compounds, especially in medicinal plants like Phyllanthus niruri. The research aim was to assess the effects of drought stress on the growth response, phenolics, and flavonoid content of P. niruri. P. niruri was subjected to drought stress for various field capacities (FC) (Control, 85%, 80%, 75%, 70%, 55%). The result showed that all observed variables are significantly different, while chlorophyll content is not entirely different. Proline content increased by 85%FC but decreased by 80%FC. The highest total fresh weight and total dry weight were shown at 85%FC but were not significantly different from 80%FC to 70%FC. These findings demonstrate that P. niruri can survive by maintaining biomass weight even after exposure to 70% FC. 80%FC treatments showed higher total flavonoids, phenols, and yield than other treatments and controls. Entire flavonoid content strongly correlated with total phenol content, with a correlation value of 0.93. The chlorophyll content is also strongly associated with total flavonoid and phenol content of 0.51 and 0.68, respectively. Proline content is negatively correlated with total flavonoid and phenol content, indicating that higher exposure to drought stress is expected to reduce the accumulation of flavonoids and phenols. Principal component analysis (PCA) revealed that 80% FC and 70% FC treatment are expected to increase yield, total flavonoid, and phenol content. Thus, it must be optimized for further research.
