A new norneolignan derivative, clitorternalactone (1), has been isolated from the stems of Clitoria ternatea, together with six known compounds, clitorienolactone A (2), myricetin 3-glucoside (3), quercetin 3-glucoside (4), kaempferol 3-glucoside (5), taraxerol (6), and taraxerone (7). The structure of the new compound 1 was determined through spectroscopic and MS analyses. Among the isolates, compound 1 exhibited cytotoxicities with IC50 values of 2.54 ± 0.23, 3.68 ± 0.17, and 4.05 ± 0.43 μM, respectively, against DLD-1, CCRF-CEM, and IMR-32 cell lines. In addition, clitorternalactone (1), clitorienolactone A (2), quercetin 3-glucoside (4), and kaempferol 3-glucoside (5) showed potent inhibition with IC50 values of 3.05 ± 0.12, 5.44 ± 0.46, 10.20 ± 0.69, and 13.57 ± 0.36 μM, respectively, against LPS-induced NO generation.
