Abstract:
Background and Objective: The lamiaceae Martinov or Labiatae de Juss. is the large family of flowering plants, commonly known as the mint or deadnettle family. Salvia reflexa Hornem. is the important medicinal plant of this family. The objectives of this study were to determine the essential oil composition of the aerial part of the plant and to evaluate its antioxidant, antifungal and antifeedant properties. Materials and Methods: The plant essential oil was extracted by hydro distillation method and chemical composition was analyzed by gas chromatography–mass spectrometry. The antioxidant activity was evaluated in terms of DPPH radical scavenging, reducing power and metal chelating activity. The antifungal property was performed against two phytopathogenic fungi viz; Curvularia lunata and Helminthosporium maydis and antifeedant property was carried out against Spilosoma obliqua (Walker) larvae. Results: Nineteen compounds were identified which contributed 94.3% of the total oil. Palmitic acid (25.8%), phytol (24.0%), (E)-caryophyllene (12.4%) and caryophyllene oxide (10.7%) were identified as the major components. The antioxidant activity in term of DPPH radical scavenging, reducing power and metal chelating activity of the essential oil was found to be IC50 = 71.82±0.45 μg mL1, RP50 = 23.6±1.05 μg mL1 and IC50 = 70.3±1.1μg mL1, respectively. The essential oil of Salvia reflexa showed strong antifungal and antifeedant activity in a dose dependent manner. Conclusion: The detailed study reveals that the essential oil of Salvia reflexa can be used as a good antioxidant, an excellent antifungal for inhibiting the growth of fungus and a very effective antifeedant for controlling the insects.
