Abstract:Two new phenolic acids, 1, 5-O-dicaffeoyl-3-O-(4-maloyl)-quinic acid (1) and 3, 5-di-O-caffeoyl-1-O-(2-O-caffeoyl-4-maloyl)-quinic acid (2), were isolated from cultured cells of Saussurea involucrata. Their structures were elucidated using 2D NMR spectroscopy and MS. Further in vitro bioactive investigations demonstrated that 3, 5-di-O-caffeoyl-1-O-(2-O-caffeoyl-4-maloyl)-quinic acid (2) had significant scavenging activities against radicals 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) and 2, 20-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS).
