Chemical Composition, Protective Effects, and Mechanisms of Volatile Oil from Fructus Gleditsiae Abnormalis with Nasal Administration against Ischemic Injury in HFD and MCAO-Induced Rats

Fructus Gleditsiae Abnormalis (FGA) has been used as a traditional Chinese medicine (TCM) for the treatment of stroke caused by phlegm and blood stasis. However, its substance basis and mechanism of action are currently unknown. This study is aimed to analyze the constituents of the volatile oil in...
