A Review on Extraction and Biological Activities of Triterpenoid from Cyclocarya paliurus

The Cycolcarya paliurus (C. paliurus) has a long history of medicinal use as a traditional Chinese medicine to deal with diabetic, hyperlipidemic, inflammatory, and cancer, and triterpenes are one of its main active substances. Current studies on triterpenoids from C. paliurus have shown that different combinations of extraction methods and techniques have been used to isolate triterpenes from the leaves of the tree. The structures of the isolated triterpenoids from C. paliurus have also been elucidated to analyze their biological activities and conformational relationships. This paper presents a comprehensive evaluation of the triterpenes in C. paliurus in terms of extraction and purification methods, chemical structure, active functions and utilization, in order to provide a reference for the further development and utilization of triterpenoids in C. paliurus.
