Abstract

The therapy of the medicinal plants has always been a part of our environment as they have several therapeutic virtues. These properties are generally attributed to secondary metabolites. Therefore, it is critical to highlight habitat conditions and quantify active phyocompounds to optimize their phytochmical constituents. Verbena officinalis is a perennial medicinal plant, known for its rich folkloric and traditional medicinal applications. The aim of this study was to test the biological activity and phytochemicals of V. officinalis from two different habitats, as well as to address the physicochemical features of soil where V. officinalis is growing. V. officinalis favored sandy soil with low salinity. In methanol extract of V. officinalis in coastal desert, phenols exhibited the highest level (54.32 mg gallic acid g-1 dry extract) followed by flavonoids, tannins, alkaloids and finally saponins (0.56 mg g-1 dry extract). V. officinalis in coastal desert showed a high antioxidant activity with IC50 value of 2.30 mg ml-1. The extract exhibited better inhibition against gram +ve bacteria (S. aureus and B. subtilis ), than that of gram -ve isolate (Escherichia coli). The extract of V. officinalis in Inland desert  showed maximum antibacterial activity against Staphylococcus aureus and Bacillus subtilis with a diameter of 15.2 mm and 16 mm, respectively. Based on the study finding, V. officinalis contains potential antimicrobial components that may be of great use for the development of pharmaceutical industries as an alternative therapy against various bacterial diseases.
