PEP: phenylpropanoids portion; PEP + ALK + OA: the mixtures of phenylpropanoids, alkaloids, and organic acid portions. Cell control: normal cells without virus infection and drug treatments. Virus control: cells infected with influenza A FM1 virus. Data of OD560 was mean ± SD. The asterisks indicate a significant difference between the test samples and the virus control according to Student’s t-test. .
