Bacteriostasis and Antioxidation of Different Solvent Extracts from FLOS CARYOPHYLLI and CORTEX MAGNOLIAE OFFICINALIS

摘要(Abstract):

[Objective] The aim was to study on the bacteriostasis and antioxidation of the different solvent extracts from FLOS CARYOPHYLLI and CORTEX MAGNOLIAE OFFICINALIS. [Method] The ethanol extracts from FLOS CARYOPHYLLI and CORTEX MAGNOLIAE OFFICINALIS were extracted by petroleum ether and ethyl acetate, respectively. Eight common strains were used to evaluate the antimicrobial activity of the extracts by filter paper method; and the antioxidation activities of the extracts were determined, respectively, by DPPH method and Rancimat method. [Result] Petroleum ether extract from FLOS CARYOPHYLLI, petroleum ether extract and ethyl acetate extract from CORTEX MAGNOLIAE OFFICINALIS had relatively strong bactericidal capacity to all the tested strains. Extracts from FLOS CARYOPHYLLI had relatively strong scavenging capacity to DPPH free radical, while those from CORTEX MAGNOLIAE OFFICINALIS were relatively weak. The antioxidant activities of extracting solutions in lard system were in the order of ethyl acetate extract from CORTEX MAGNOLIAE OFFICINALIS>petroleum ether extract from CORTEX MAGNOLIAE OFFICINALIS>ethyl acetate extract from FLOS CARYOPHYLLI>petroleum ether extract from FLOS CARYOPHYLLI>water extract from FLOS CARYOPHYLLI>water extract from CORTEX MAGNOLIAE OFFICINALIS. [Conclusion] This research provided scientific basis for exploring natural food preservatives and antioxidants.
