An Investigation of Phytochemical, Total Phenolic and Flavonoid Contents and Antioxidant Activity in Aerial Parts of Two Species of Salvia and the Effect of Environmental Factors on their Distribution in Behshahr Hezarjarib Area

Abstract

The purpose of this study was an investigation of phytochemical and antioxidant characteristics in aerial parts of Salvia multicaulis Vahl and Salvia sclarea L. and the effect of ecological factors on their distribution in Behshahr Hezarjarib area. Salvia grows wildly in the north of Iran. Literature review has shown that there is no report on phytochemical investigation about aerial parts of Salvia in north of Iran. In order to understand the relationship between vegetation and environmental factors, the PCA (Principle Component Analysis) method has been adopted. Essential oil of the aerial part of Salvia was analyzed by GC/MS. Antioxidant activities were evaluated by DPPH test. Thirteen and five components were identified representing 94.01% and 99.9% of the oils, respectively. The main compounds of salvia multicaulis Vahl were α-Pinene (29.82), 1,8-Cineole (23.84) and Camphor (19.93) while 1,6-Cyclodecadiene (41.95) and β-Caryophyllene (36.19) were the major ingredients of Salvia Sclarea L.
