Evaluation Potential of Strobilanthes Auriculata var. Dyeriana (Mast.) J.R.I. Wood as an Antioxidant and Antimicrobial Agent

Strobilanthes belongs to the Acanthaceae family and possesses various medicinal qualities, including wound healing, antioxidant, antibacterial, antidiabetic, anticancer, and anti-inflammatory effects. One species in this genus, Strobilanthes auriculata var. dyeriana, is a popular ornamental plant that has long been used as a diuretic to alleviate rheumatism. While few are recognised, this species likely has many more benefits. This study examined the phytochemical composition, phenolic content, anthocyanin content, and antibacterial and antioxidant qualities of S. auriculata var. dyeriana leaf extract. Finding no anthocyanin, we discovered that the leaves of this species contained phenolic compounds (82.9±0.86 μg/100μg). Furthermore, vigorous antioxidant activity (IC50 96.17 ppm) and growth-inhibiting action against Salmonella typhimurium are provided by high phenolic content. According to this study, the leaf of S. auriculata var. dyeriana may act as a potential antibacterial and antioxidant agent.
