Phytochemical Analysis, Isolation and Identification of Flavan-3ol from Syrian Pinus Halepensis

Abstract

The present study is carried out with steam bark of pinus halepensis : A simple and fast method was developed for flavan-3ol from steam bark of pinus halepensis using by flash column chromatography then purification were conducted by preparative chromatography The structures of these compound were characterised by comparing their spectral data including 1D and 2D NMR with those reported in the literature The qualitative phytochemical analysis revealed that, extracts of (green dry parts from plant) contain tannins, flavonoids, terpenoids, alkaloids as well as steroids. phenolic flavonoids, the molecular structures have determinate by spectroscopy methods :FT-IR, MS, 1H-NMR, 13C-NMR, DEPT (90,135), HMQS, COSY and HMBC.

Keywords: pinus halepensis, flavan-3ol, Phytochemicals, NMR.
