In order to find more biologically active substances,we have carefully investigated the chemical constituents of Pterocypsela elata.One new guaianolide,(4S)-11-methoxycarbonyl-guaiane-1(10),5(6),7(11),8(9)-tetraen-6,12-olide was isolated from the EtOAc extracts of the roots of P.elata. Its structure was elucidated by various spectroscopic methods and confirmed by X-ray crystallographic analysis.
