Variation in phenolic, antioxidant and vitamin amounts among some medicinal plants and investigation by PCA analysis: Lamiaceae family

Abstract

Aromatic and medicinal plants are of great importance to determine the contents of the active compounds of plant origin and to evaluate them depending on variety and climate factors in order to determine the phenolic, antioxidant enzyme activity, vitamin contents in species belonging to the Lamiaceae family. Examination of the characteristics of different species, the highest peroxidase (POD) enzyme activity, ascorbate peroxidase (AxPOD), total antioxidant (TA), malondialdehyte (MDA), caffeic acids (CA), vitamin C contents,and chloric acid (ChA) were obtained in the M. longifoliaspecies. The highest vitamin E and catalase (CAT) were determined in the S. hortensisspecies but the highest total phenolic (TP), superoxide dismutase (SOD) enzyme, hydrogen peroxide (H2O2) and chlorogenic acid (ChgA) were determined in the S. spicigeraspecies. As a result of PCA analysis, it can be said that Mentha longifolia(L.) Hudson and Satureja spicigeraspecies have significant value in terms of biochemical and phenolic content.
