Study on the Spectrum-effect Relationship of Anti-inflammation Effect in vitro of Extracts from Uygur Medicine Hyssopus cuspidatus / 中国药房

ABSTRACT

OBJECTIVE:To provide reference for clarifying the pharmacodynamic material basis of anti-inflammation effect of Uygur medicine Hyssopus cuspidatus. METHODS:HPLC was conducted to establish the fingerprint of 8 extracts with different po-larities. Using macrophage RAW264.7 as object,the inhibitory effect of extracts with different polarities on inflammatory factor ni-tric oxide(NO),TNF-α and IL-6 in supernatant of cell culture medium was detected,the differences of anti-inflammatory activity in vitro were compared. Grey correlation analysis method was used to analyze the spectrum-effect relationship of peak area of common peaks and anti-inflammation activity. RESULTS:The fingerprint of 8 extracts with different polarities showed obvious differences. Anti-inflammation in vitro results suggested that 30% ethanol extract had the strongest inhibitory effect on inflammatory cytokines in vitro. There were 14 common peaks in the established HPLC fingerprints,the 5 common peaks that was closely related to the in-hibitory effect of inflammatory factors in vitro were peak 8,6,5,10,13,respectively;peak 8 was rosmarinic acid. CONCLUSIONS:The established fingerprint and its spectrum-effect relationship with anti-inflammation activity in vitro can provide certain reference for its pharmacodynanic material basis study.
