OBJECTIVE: The experiment attempts to study the antioxidant activity in different parts of Gardenia jasminoides including roots, stems, leaves, branches, flowers and fruits to explore the development and utilization of new medicinal parts of Gardenia jasminoides. METHODS: Apply microwave-assisted extraction( MAE) to extract total flavonoids from different parts of Gardenia jasminoides including roots, leaves, fruits, flowers and stems and register the ethanol concentration, extraction temperature and extraction time of microwave-assisted extraction.RESULT: The total polyphenols content in different parts of Gardenia jasminoides was arranged from high to low as: leaves, branches, fruits, flowers, stems, roots; the total flavonoids content in different parts of Gardenia jasminoides was arranged from high to low as: leaves, Branches, fruits, stems, roots, flowers; the DPPH radical scavenging activity(IC50) in different parts of Gardenia jasminoides was arranged from high to low as: leaves, branches, fruits, flowers, stems, roots; the dry extract rate was arranged from high to low as: fruits, leaves, branches, flowers, stems, roots.
