摘要
One new monoterpenoid, nerol oxide-8-carboxylic acid (1), and one new flavonoid glycoside, claulansoside A (2), together with six known compounds, clausenamide (3), quercetin (4), isorhamnetin (5), dihydromyric (6), 2 '',3 ''-dihydroxyanisolactone (7) and (E,E)-8-(7-hydroxy-3,7-dimethylocta-2,5-dienyloxy)psoralen (8), have been isolated from the peels of Clausena lansiunz (Lour.) Skeels. Their structures were determined using a combination of ID, and 2D NMR (HMQC, HMBC, COSY and NOESY) techniques, and HR-ESI-MS analyses. Compounds 1 and 7 exhibited antibacterial activity against Staphylococcus aureus with the diameter of inhibition zones of 11.5 mm and 14.2 mm. Compounds 3 and 6 showed a-glucosidase inhibitory activity in vitro.
