摘要:
The new norisoprenoid 3 beta-hydroxy-5 alpha,6 alpha-epoxy-beta-ionone-2 alpha-O-beta-D-glucopyranoside ( 1) and the long-chain hydroxy fatty acids 9,12,13-trihydroxyoctadeca-10(E), 15(Z)-dienoic acid ( 2) and 9,12,13-trihydroxyoctadeca-10( E)-dienoic acid ( 3) were isolated from Salsola tetrandra aerial parts, together with 3,4,5-trimethoxyphenyl-beta-D-glucopyranoside ( 4), 9-hydroxylinaloyl glucoside ( 5), taxiphyllin ( 6), trans-N-feruloyltyramine ( 7), and S-(-)-trans-N-feruloyloctopamine ( 8). Their structures were elucidated by extensive spectroscopic analysis and chemical methods. Compounds 6 and 8 displayed mild antibacterial activity against Staphylococcus aureus, whereas compound 6 showed the highest activity in the Artemia salina bioassay.
