Abstract

Two new phthalates bis(2-ethylundecyl)phthalate (1) and bis(2-ethyltridecyl)phthalate (2) have been isolated from the chloroform-soluble portion of the whole plant of Nepeta clarkei along with one known compound β-amyrin. The structures of the two new compounds and β-amyrin were assigned on the basis of their 1H and 13C NMR spectra including 2D NMR techniques such as COSY, HMQC, and HMBC experiments and compared with the literature data.
