ABSTRACT * Author for correspondence and reprint requests Z. Naturforsch. 64c, 809-812 (2009); received May 7/July 23, 2009 Menthalactone, a new long-chain alkene with a bicyclic lactone moiety, was isolated as an analgesic constituent from the leaves of Mentha cordifolia Opiz. At a dosage of 100 mg/ kg mouse, it decreased the number of squirms induced by acetic acid by 67.3%. Statistical analysis using Kruskall Wallis one-way analysis of variance by ranks showed that menthalac-tone is different from the solvent control at alpha = 0.01 and approximates the analgesic activity of mefenamic acid at 0.001 level of significance.

    ABSTRACT: A phytochemical study of the 95% ethanolic extract of the whole plant of Lancea tibetica Hook. f. et Thoms. led to the isolation of a new trehalose ester, 6-O-undecanoyl-α,β-trehalose (1), along with 23 known compounds (2-24), of which compounds 2-17 were isolated from this plant for the first time. The structures of these compounds were established on the basis of spectroscopic methods. Compound 1 was evaluated for their in vitro anti-proliferative activities against MCF-7, NCI-H460 and Hep-G2 tumour cell lines. Compound 1 exhibited potent inhibitory activity against NCI-H460 cell growth, in contrast to moderate cytotoxic activity against MCF-7 and Hep-G2 cells.
