Quassia indica (Gaertn.) Nooteboom is classified under the family Simaroubaceae. Species from Simaroubaceae are known to contain chemical compounds such as quassinoids due to its bitter taste. This project was mainly focused on the systematic studies of the morphological, wood anatomical, leaf epidennis structures of Q. indica and the preliminary analysis of the chemical compound present in the plant. The materials and methods include samples collection, preparation of wood samples, leaf samples, microscopic slides preparation, and microscopic observation to obtain detailed infonnation on anatomy structure of wood and leaf of the species. The vessel element of the wood cross section was diffuse and solitary porous with uniseriate parenchyma rays. The leaf epidennis cells of Q. indica were isodiametric and posses a mixture of tetracytic and polycytic stomata. Apart from this, phytochemical analyses were also conducted on Q. indica to examine the chemical component present. The analysis includes extraction of the leaves, stems and roots using hexane, ethyl acetate and methanol and phytochemical evaluation of extracts using HI Nuclear Magnetic Resonance (NMR) spectroscopy analyses. Types of proton detennined in this analysis were classified under alkane, methyl ketone, acetylenic, vinyl, allylic, aromatic, benzylic, ald~hyde, phenol, hydroxyl and methoxy. Further studies on the chemical compound of Q. indica should be undertaken to detennine the specific compound present in the species.
