Hypericum perforatum L. (St. John’s wort) is a well-known species in the Genus Hypericum and the plant is widely used as an herbal drug for the treatment of mild to moderate depression disease. The present study was aimed to evaluate ten populations of H. perforatum using agro-morphological characteristics and some composition of essential oil. The main constituent of essential oil composition in this study was α- pinene, 2- methyl octane, delta-cadinene and γ-cadinene. The result showed the high and significant correlation coefficients among the most of measured characters including positive correlation between leaf area with inflorescence internode spaces (r= 0.771), plant width with inflorescence length (r= 0.894) and delta-cadinene with E-cariophyllene (r= 0.739). There was a negative correlation between length/width capsule with flower number in primary inflorescence (r= -0.8) and secondary inflorescence branches (r= 0.887). The result of factor analyses showed that seven independent and major factors, explain 95.47% of variation of all data and some traits such as inflorescence length, number of flower in main inflorescence, leaf area and length were attributed to main factors. This study showed that the highest number of flower was observed in the plants originated from Galogah region.
