    Abstract: 微生物發酵並配合以HPLC進行成分分析,發現發酵前後之cichoric acid含量有明顯差異。本研究指出經過微生物發酵後,紫錐菊中的cichoric acid可伴隨著酒精的產出而被萃取出來,濃度比發酵前增加三倍。若是不經微生物發酵,單獨以15%乙醇浸泡相同的發酵時間,則萃取出的cichoric acid濃度只有發酵的8%(發酵液第4天)。在菌根菌接種實驗中,接種菌根菌的紫錐菊(VA組)總乾重比未接種菌根菌的紫錐菊(CK組)高,實驗中也發現VA組葉子cichoric acid濃度為473 μg/mL,CK組卻只有246 μg/mL。在一連串的實驗中,利用菌根菌接種來提高紫錐菊中的cichoric acid,並利用微生物發酵的方法,有助於開發紫錐菊的新產品,並提升紫錐菊的應用價值與商業利益。
