Polianthes tuberosa (Linn.) is traditionally considered an ornamental and medicinal plant worldwide. However, extensive studies on its phytochemical composition are very limited. Hence the present work aims to identify the total phytochemical ingredients present in different crude extracts of tuberosa. Phytochemical analysis has been carried out for differential cold solvent extracts of various parts of tuberosa such as petals, stamens, and ovary by gas chromatography coupled with mass spectrometry, ultra‐performance liquid chromatography to quadrupole time‐of‐flight mass spectrometry, and evaporative light scattering detector analyzers for the identification of bioactive components. Among the various solvents used for the extraction, diethyl ether is found to be the most suitable and efficient solvent, as its total differential recovery from the crude extract is about 0.24% as compared to 0.04% obtained by using n‐hexane or petroleum ether. Numerous phytochemicals have been identified by the chromatography and MS techniques, which demonstrate the presence of essential fatty acids along with other pharmacological importance phytoconstituents. Identification of additional phytochemicals present in the crude extract of tuberosa flower further enhances its biological and pharmacological significance. The present work lays a foundation for further research and development of phytoconstituents of the tuberosa flower.
