Cyperus rotundus (Cyperaceae) has been widely used in traditional medicine for the treatment of various diseases, including cancer. Although an anti-tumour effect has been suggested for C. rotundus, the anti-tumour effects and underlying molecular mechanisms of its bioactive compounds are poorly
A new patchoulane-type sesquiterpenoid glycoside (1), together with five known sesquiterpenoids (2-6), was isolated from the roots of Croton crassifolius. Their structures were elucidated on the basis of spectroscopic methods. This is the first report about the sesquiterpenoid glycoside from C.
Cyperenoic acid (1) is one of the major sesquiterpenes isolated from Croton crassifolius, which exhibited potent anti-angiogenic activity. Traditional structural modification of 1 is difficult to perform by chemical technology due to the remarkable stability of the patchoulane skeleton. In order to
