Eleven new seco‐iridoids, valeridoids G‐Q (1–6 and 8–12), along with four known products, 9‐epi‐valtral C (7), desacylbaldrinal (13), 11‐methoxyviburtinal (14) and baldrinal (15), were obtained from Valeriana jatamansi. Among them, the new compounds were identified by their NMR, HR‐ESI‐MS spectroscopic data and ECD calculation. Moreover, valeridoid N and O were a pair of C3 epimers, whose ether bonds...
In this study, total flavonoids and total triterpenoid acid were extracted with ethyl acetate from Hedyotis diffusa Willd, and hepatoprotective activities of them and five compounds from total flavonoids against H2O2 induced hepatocyte damage on HL‐02 cells were determined. In particular, amentoflavone and total flavonoids had influence on the leakage of ALT, AST, LDH, the activities of SOD and the...
