Gas Chromatography-Mass Spectroscopy Profiling of Petroleum Ether Extract of Tabernaemontana divaricata Leaves

Background: Tabernaemontana divaricata (TD), commonly known as Crape Jasmine, plays a very
substantial function in treatment of various diseases since time immemorial.
Objective: The extract suggests the existence of numerous compound classes, along with alkaloids,
tannins, hormones, saponins, proteins, triterpenoids, flavonoids, phenylpropanoids, and reducing
sugars. This plant has been reported for diverse set of bio-activities such as its potential curative role
in healing infections, halting the tumor progression and enhancing action of cholinergic activity
systems.
Methods: Present research study mainly involves the identification of chemical constituents in
petroleum ether extract of Tabernaemontana divaricata leaves (PETD) through a hyphenated
technique of coupling of Gas chromatography with Mass Spectroscopy (GC-MS).
Results: A total of 35 components were identified from the PETD extract. Mass spectra of elucidated
components were characterized by comparing libraries of mass spectrums. Some of the components
identified are Styrene, D-glycero-D-manno-, Mesitylene, Z,Z-2,5-Pentadecadien-1-ol, Pterin-6-
carboxylic acid, L-α-Terpineol, Cyclodecanol, (-)-Carvone, 2-Myristynoyl pantetheine, Cubedol,
Benzophenone, Palmitic acid, 9-Octadecanoic acid(Z), Stearic acid etc.
Conclusion: This article would further help the researchers to get proper insight to the important
phytoconstituents present in TD plant with different extracts.
