Phytochemical Analysis of Cultivated and Wild Salvia Palaestina using GC-MS: A comparative study
The leaves of cultivated populations of Salvia palaestina (Lamiaceae) were collected from seven different governorates in Palestine to compare their phytochemical profiles to wild populations. Twenty volatile and semivolatile components were separated and identified by GC-MS. The major components in all the cultivated S. palaestina leaves were eucalyptol and camphor excluding one sample that was collected from Jericho. This sample revealed camphor as the predominant component (30.65%) while in the rest of the cultivated samples, camphor did not exceed 9.2% level. Moreover, thujone derivatives in Jericho's sample were abundant at high concentrations (28.9%) in comparison to other populations which did not exceed more than 2%. The wild S. palaestina leaves, showed eucalyptol as a major component in all samples from different locations with higher concentration than the cultivated leaves, while the later had a higher amount of camphor.
