It is often recognized that India is home to a diverse range of biological species. For this study, Agathis robusta were employed. The present investigation aimed to determine the total phenolic and flavonoid contents of the selected plants and investigate the presence of phytochemicals. stems and leaves of A. robusta were collected, dried, and ground into a fine powder. The powdered leaves were extracted using a Soxhlet method and ethyl acetate. The finished extract was concentrated while the pressure was decreased to produce a crude extract. To determine the amount of sugar, carotenoid, and total protein in the crude extract, a phytochemical screening was conducted using standard qualitative procedures. A. robusta leaf ethyl acetate extract showed the presence of several phytochemicals. Significant amounts of terpenoids, flavonoids, alkaloids, and tannins were found in the extract. These substances' existence suggests that they may have pharmacological effects, such as antibacterial, anti-inflammatory, and antioxidant capabilities. The ethyl acetate extract of A. robusta leaves revealed the presence of several phytochemicals. The extract included notable concentrations of tannins, alkaloids, flavonoids, and terpenoids. The presence of these compounds raises the possibility that they have pharmacological properties including antioxidant, anti-inflammatory, and antibacterial properties.
