Abstract
OBJECTIVE: To study the chemical constituents in the volatile oil from fruits of Alpinia oxyphylla. METHOD: Using GC-MS to identify the constituents. RESULT AND CONCLUSION: Sixty-four compounds were identified on the basis of GC-MS, the main ones being p-cymene, valence, linalool, myrtenal, alpha-pinene, beta-pinene, furopelargone A and terpinen-4-ol. Three sesquiterpenes valencene, nootkanone and nootkanol have been isolated from the CHCl3 extract as check, of these 64 identified compounds linalyl oxide, valencene, bakkenolide A, furopelargone A and 3-hydroxycalamenene are reported for the first time.
