(1) The content of muscone was determined by GC.

(2) Method: The muscone content in Gujukang Extract was determined by gas chromatography.

(3) Objective:To investigate the effect of muscone on neuronal glutamate transporter EAAC_1 transcriptional level at different is- chemic times in acute ischemic hippocampus in rats.

(4) Objective: To study the effect of muscone on attenuating excitotoxity and brain damage in acute cerebral ischemia.

(5) Objective : To study the effect of muscone attenuating excitotoxity and brain damage in acute cerebral ischemia.

(6) Objective To establish a method for the determination of cinnamaldehyde and qualitative identification of muscone in Yaotongling suppository.

(7) Conclusion: Gas chromatography is exclusive and feasible in determining muscone content in Gujukang Extract.

(8) Objective: To control the quality of Gujukang with the target of muscone content.

(9) So far, we have synthesized pentadecane diacid [], which is a very important intermediate product during preparing muscone.

(10) So far, we have synthesized diacid, which is a very important intermediate product during preparing muscone.
