SPECTRAL ANALYSIS OF PETROLEUM ETHER AERIAL PART EXTRACT OF GRANGEA MADERASPATANA USING GAS CHROMATOGRAPHY-MASS SPECTROMETRY

Grangea maderaspatana, commonly known as Madras carpet / Indian chickweed and belonging to the Asteraceae family. This plant is widely distributed throughout the tropical and subtropical regions of Asia and Africa and traditionally employed in the management of respiratory, gastrointestinal and dermatological disorders. Grangea maderaspatana plant has also demonstrated potential anti-inflammatory, analgesic and antimicrobial activities. This study investigates the chemical composition of the petroleum ether extract of aerial part of Grangea maderaspatana using Gas Chromatography-Mass Spectrometry (GC-MS). The plant, known for its traditional medicinal uses, was subjected to Soxhlet extraction and the extract was analyzed to identify its phytochemical components. The analysis revealed a complex mixture of hydrocarbons, fatty acids, terpenes and other organic compounds with tetracontane (45.20% area at different retention time), n-hexadecanoic acid (7.05%area), (S,Z)-heptadeca-1,9-dien-4,6-diyn-3-ol (6.18% area at different R. Time) and neophytadiene (5.08%area) being the major components. The presence of these compounds suggests potential applications in pharmaceuticals, cosmetics and other industries due to their bioactive properties.
