| Abstract: |
| Five frangipanies were prepared to analyze the content of ascorbic acid and changes of physiological
parameters in their leaves and petals. The main purpose was to provide data basis for breeding the high quality
of frangipani variety that is suitable for local environments. The results showed that contents of ascorbic acid，
chlorophyll，carotenoid，malonaldehyde，flavonoid，oligomeric proantho cyanidins as well as the activities of POD
and SOD enzymes in the leaves and petals of different frangipani varieties were observed. It was indicated the variety
specificity of the antioxidants involved in the scavenging of reactive oxidants in different frangipanies. On the other
hand，the higher content of flavonoid in the petals than the leaves was observed，suggesting the important role of
flavonoid as antioxidant in the flower organ of frangipani. |
