Study on the Components and Antioxidant Activites of the Liposoluble Constituents from Murdannia Nudiflora (Linn.) Brenan

OBJECTIVE To analyze the components and antioxidant activites of the liposoluble constituents from Murdannia nudiflora (Linn.) Brenan.METHODS The liposoluble constituents from Murdannia nudiflora (Linn.) Brenan were analyzed by GC-MS and identified by the searching of standard mass spectral library on computer. The antioxidant activites were detected by DPPH free radical and ABTS free radical scavenging method.RESULTS The 23 compounds were identified from Murdannia nudiflora (Linn.), and the half elimination ratio (IC₅₀) of scavenging activity of free radical in DPPH and ABTS were 5.255, 3.848 mg·mL^-1, respectively.CONCLUSION The bioassay indicated that the liposoluble constituents from Murdannia nudiflora (Linn.) Brenan possessed antioxidant activites. Unsaturated fatty acid and phytol are major chemical constituents of these components. All the compounds were identified from this plant for the first time. The liposoluble constituents from Murdannia nudiflora (Linn.) Brenan possessed antioxidant activites.
