Clinacanthus nutan  is an important herb species from the family Acanthaceae and is commonly found in Southeast Asia. It is also known as snake grass, or  ‘belalai gajah’ in malay. The leaves of  C. nutan  can be used to make a refreshing juice or tea, or even consumed raw as ‘ulam’, a traditional malay salad. In this work, the leaves, stems, and a mixture of both leaves and stems of  C. nutan  are first dried in an oven at 50°C for 24 hours and then grounded into a powder. Then, pressurized hot water extraction (PHWE) is used to extract phytochemicals from the powdered samples at 120°C for 20 minutes. This work investigates the effects of three important parameters for extraction; the sample particle size (&lt;63 to 500μm), solventto-sample ratio (10:2 to 50:2 v/w), and sample weight (0.5 to 3.0g) on the extracted phytochemicals’ total phenolic compounds (TPC), total flavonoid compounds (TFC), and 2,2-dipheny1-1picrylhydrazyl (DPPH) scavenging activity. The experiments are carried out in triplicate and the results are analyzed using Minitab. Phytochemicals extracted from 2g leaf powder samples of particle size &lt;63μm using a solvent-tosample ratio of 50:2 (v/w) resulted in the most favorable results for TPC, TFC, and DPPH scavenging activity. The results are found to be significant with the
