Abstract:

Taking Calotropis gigantean as material，liposoluble constituents of Calotropis gigantean’s flower，fruit and leave were extracted by soxhlet extraction.The antibacterial activities on Escherichia coli，Proteus vulgaris and Bacillus subtilis of three fractions were studied by inhibition zone method and minimal inhibitory concentration (MIC) method to study the bacteriostatic activity of different parts of Calotropis gigantean liposoluble extraction.The results showed that the antibacterial activity of liposoluble extraction in different parts of Calotropis gigantean were the highest for Escherichia coli，while leave extraction exhibited the strongest bacteriostatic activity.The minimal inhibitory concentration (MIC) of leaves liposoluble extraction against for Escherichia coli and Proteus vulgaris were 30 mg/mL，60 mg/mL respectively.The wild Calotropis gigantean liposoluble extractions had a good bacteriostatic activity.The study could provide theoretical foundation for further studying and developing of the Calotropis gigantean.
