Photosynthetic organs of wild Indian tea tree are rich in patchouli components: a GC-MS based metabolomics

Gas chromatography-mass spectrometry is an essential tool for metabolomics. In this research we have selected photosynthetic organs- leaf and sepal of a wild Indian tea tree from north-east India to study wild tea metabolites. The result of this study reveals that photosynthetic parts of wild Indian tea tree are rich in ‘patchouli’ components unlike established cultivated varieties which are known to be rich in polyphenols or flavonoids. Twenty six compounds were detected in sesquiterpene rich leaf while nineteen were detected in the waxy sepal. The remarkable outcome of this study is presence of fourteen ‘patchouli’ compounds including patchouli alcohol as the major compound (44.81% in leaf and 19.59% in sepal) which can promote this plant to a top-notch position in fields of botany, pharmaceuticals and essential oil industry by occupying the throne of patchouli.
