Nowadays, traditional plant study has grown in importance as their use has been increased. Tectona grandis (teak) is one of several plants that have been studied for its phytochemical and pharmacological properties. This plant includes a number of secondary metabolites, which may explain its diverse pharmacological properties. Although teak leaf compounds have been examined in the past, there is still little information on the diversity of teak leaf compounds. As a result, we are employing several methodologies to determine the total flavonoids content, phenolic content, water extractable matter, ethanol extractable matter, total ash content, and other component analysis of teak leaves. We found that the average of total flavonoid content in the teak leaves is about 3.93 {\textpm} 0.008\%w/w, while the average total phenolic concentration in teak leaves is about 4.3{\textpm}0.15\%w/w. The Gas Chromatography- Mass Spectrometry GC-MS study of the methanol extract of T. grandis leaves also found twenty-three active chemical compounds (phytochemical components)
