The purposes of this research were to investigate volatile constituents and biological activities of Gardenia jasminoides J. Ellis flowers. Hydro-distillation and solvent extraction were used as the extraction methods to obtained essential oil and absolute, respectively. The chemical constituents of essential oils were characterized by GC-MS with KI. Absolute and fresh flowers were identified by Headspace-SPME-GC-MS. Major chemical constituents of the essential oil, absolute and fresh flowers of G. jasminoides were linalool, alpha-farnesene, z-3-hexenyl tiglate and trans-beta-ocimene. The essential oil and absolute possessed antimicrobial activities against Staphylococcus aureus and Staphylococcus. epidermidis, the activity towards Escherichia coli presented for only essential oil and the activity against Candida albicans appeared for only absolute. The essential oil exhibited TEAC 2.56 mg Trolox/1 ml essential oil and FRAP 7.27 mg Fe2+/1 ml essential oil. The absolute presented TEAC 29.71 mg Trolox/1 g absolute and FRAP 77.96 mg Fe2+/1 g absolute.
