title: Two new phthalate derivatives from Nepeta clarkei (Labiatae).
abstract: Two new phthalates bis(2-ethylundecyl)phthalate and bis(2-ethyltridecyl)phthalate 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.
