Stachys lavandulifoliaVahl. is one of the 34 species of the genus Stachys, growing naturally in Iran. In this study, the natural habitats of Stachys lavavandulifolia were identified in different regions of Alborz, Kurdistan, West Azarbaijan and East Azarbaijan. Ten complete plants were collected from eight localities in order to study and evaluate morphological traits. Flowering stems were used to investigate essential oil quantitatively. Data of locations and vegetative and reproductive characters of each population were recorded and the amount of essential oil of each location was measured. Results were analyzed using cluster analysis method with SPSS and SAS softwares and the correlation between evaluated traits and essential oil productivity was determined.The traits evaluated in the populations were classified in two distinct groups by cluster analysis. Populations collected from Alborz (Gachsar), Kurdistan (Saqez) and West Azarbaijan (Manbar, Baba nazar, Chahar tagh and Damerchi) were classified in same group and populations from East Azarbaijan (Azarshahr and Ajabshiri) were classified in a separate group. Differences between these two groups may be due to the different climates in the habitats and adaptation of this species to different environmental factors. As a result, Azarshar population, due to having better vegetative and reproductive traits and high essential oil yield as compared to other populations could be taken into consideration for breeding programs or for cultivation and production.

GenusSalvia, belonging to the Labiatae family, has valuable active ingredients including essential oils, flavonoids and rosmarinic acid. Pharmacological researches on Salvia genus have confirmed medicinal properties of the plant including antibacterial and antioxidant effects. Total flavonoids, rosmarinic acid and the content and chemical compounds of essential oil of three populations of Salvia reuterana Boiss., collected from three regions of Iran (Deli chai, Kaswa and Shahmirzad), as well as Salvia palaestina Benth., collected from Rodbarak, were evaluated in present study. Fifty-six compounds of S. reuterana and S. palaestina were identified by GC-MS. The most important chemical compositions for S. reuterana were α-gurjunen, β-elemene, germacern-D, N-hexyl acetate and spatholenol and for S. palaestina were caryophyllen, dihydro carveol, germacern-D, linalool and spatholenol. Diethyl ether extract of leaves was used for quantification and identification of flavonoids and rosmarinic acid. The crushed leaves of the plant were dissolved in diethyl ether solvent and then were injected into the LC-DAD-ESI-MS system. Total flavonoids amount of S. reuterana, collected from Kaswa, Deli chai and Shahmirzad were calculated to be 3252.76, 3697.19 and 5132.92 µg/ g, respectively. Also the amount of rosmarinic acid in plants, collected from Kaswa, Deli chai and Shahmirzad was 122, 177.11 and 98.46 µg/ g, respectively. S. palaestina Rodbarak showed 3808 and 19.72 µg/g of total flavonoids and rosmarinic acid, respectively.
