摘要 In order to find more biologically active substances, we have carefully investigated the chemical constituents of Pterocypsela elata. One new guaianolide, (4S)-ll-methoxycarbonyl-guaiane- l(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.
