The purpose of this study was to investigate the bioactivity of extracts from the seeds of Gardenia jasminoides Ellis fructus (GJE) found in Namhae, Korea. Extraction was performed using three solvents, 70% methanol, Distilled Water (DW), and Ethyl Acetate (EA). We determined the total phenol and phytic acid contents of the extracts to evaluate their nitrogen oxide scavenging activity, antioxidant activity, reducing power, and lipid peroxidation inhibition ability. The phytic acid content of GJE was found to be 1.157 mg PAE (Phytic Acid Equivalent) /g DW. The yields of the three extraction processes were as follows: DW, 36.61%; 70% methanol, 30.10%; and EA, 20.40%. The physiological activities of the extract solvents increased significantly with increasing concentrations (0.2, 0.4, and 0.6 mg/mL) (p<0.05), but were lower than those of ascorbic acid, BHA, and trolox. Total phenol content was the highest in the 70% methanol extract, followed by DW and EA extracts. Further, nitrogen oxide scavenging activity and antioxidant activity were the highest for the 70% methanol extract followed by DW and EA extracts. Based on these results, the bioactivities of the 70% methanol and DW extracts of GJ seeds were excellent. These extracts can be used as natural antioxidants.
