OBJECTIVE
To separate and identify cyclopeptides of tubers of Rubia schumanniana.
METHOD
The 70% methanol extracts from tubers of Rubia schumanniana were separated and purified by silica gel, RP-18, Sephedax LH-20 and HPLC. Their structures were identified by spectral analysis.
RESULT
Nine cyclopeptides were separated and identified as RA- II (1), RA-V (2), RA-VIII (3), rubiyunnanin C (4), RA-X (5), RY-II (6), RA- I (7), RA-XIII (8) and RA-XIII-OMe (9), respectively.
CONCLUSION
All of nine cyclopeptides were separated from R. schumanniana for the first time.
目的
分离并鉴定云南茜草块茎中的环肽。
方法
采用硅胶柱色谱、RP - 18柱色谱、Sephedax LH - 20柱色谱及高效液相色谱法对云南茜草块茎70%甲醇提取物进行分离纯化，通过光谱分析鉴定其结构。
结果
分离得到9个环肽，分别鉴定为RA - II（1）、RA - V（2）、RA - VIII（3）、rubiyunnanin C（4）、RA - X（5）、RY - II（6）、RA - I（7）、RA - XIII（8）和RA - XIII - OMe（9）。
结论
9个环肽均首次从云南茜草中分离得到。
