Preliminary Phytochemical and GC-MS analysis of chemical constituents of Iraqi Plantago lanceoleta L.

Abstract

Plantago lanceoleta L. is one of medicinally important plant that officially registered in British pharmacopoeia. One of their well-known common name is ribwort, which is rich in many phytochemical compounds. The goal of this study is the qualitative evaluation of the Iraqi plant by identifying its chemical constituents. The plant was authenticated, collected, and immediately subjected to a stream of air under room temperature for rapid drying. Each part of the plant extracted separately with 50% ethanol and tested for presence of iridoid glycosides, tannins, flavonoids, terpenoids, alkaloids and saponins. While the other part of phytochemical screening of Iraqi P. lanceoleta L. in this work is the chromatographic fingerprint analysis of n-hexane extract of the plant leaves by gas chromatography-mass spectrometry (GC-MS). The result obtained show that Iraqi P. lanceoleta L. is rich in iridoid glycosides and tannins in each part of the plant, while the chromatogram of GC-MS show that the Iraqi plant contains high amount of hydrocarbons, fatty acids, steroids, terpenoids and other constituents.
