Study on Liposoluble Constituents from Glochidion Sphaerogynum (Muell. Arg.) Kurz and Its Antioxidant Activities

OBJECTIVE To analyze the components and antioxidant activites of the liposoluble constituents from Glochidion sphaerogynum (Muell. Arg.) Kurz. METHODS The liposoluble constituents from Glochidion sphaerogynum (Muell. Arg.) Kurz 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 47 compounds were identified from Glochidion sphaerogynum (Muell. Arg.) Kurz, and the half elimination ratio(IC₅₀) of scavenging activity of free radical in DPPH and ABTS⁺ were 1.103, 0.726 mg·mL^-1. CONCLUSION Unsaturated fatty acid and phytol are major chemical constituents of the liposoluble constituents from Glochidion sphaerogynum (Muell. Arg.) Kurz. All the compounds were identified from this plant for the first time. The liposoluble constituents possessed antioxidant activites.
