Notes: Cell control: normal cells without virus infection and drug treatments. Virus control: cells infected with influenza virus. PEP: phenylpropanoids portion; PEP + ALK + OA: the mixtures of phenylpropanoids, alkaloids and organic acid portions. The asterisks indicate a significant difference between the test samples and the virus control according to Duncan's multiple range tests,
