The anti-candidal activity of salvia verticillata subsp. verticillata against several candida species

The examination of Salvia verticillata extract encompassed an exploration of its anti-Candida properties, phytochemical composition, antioxidant activity, and the quantification of total tannins. The use of ethanol as a solvent yielded the highest extraction efficiency at 26.1%. The plant exhibited a substantial tannin content of 6.5 mg/kg, signifying a noteworthy concentration. The inhibitory zones against Candida tropicalis reached a minimum diameter of 17.6 mm, while Candida guilliermondii displayed the most significant inhibition with a zone diameter of 21.8 mm. The minor inhibitory concentration (MIC) findings for all Candida species ranged from 6.25 to 12.5 g/ml. In the case of Candida guilliermondii, the synthetic antifungal activity FLU/25 demonstrated a maximal inhibition zone measuring 39.30 mm. Additionally, the maximum antioxidant activity, recorded at 0.3 ml, reached a value of 98.65. Phytochemical screening unveiled elevated concentrations of phenols and flavonoids, with malic acid (1901.1 g/g), hesperidin (302.4 g/g), and rosmarinic acid (30619.93 g/g) all experiencing an increase in concentration. These findings provide a comprehensive understanding of the diverse bioactive components and properties associated with Salvia verticillata extract.
