The iridoids of H. diffusa play an important role in the anti-inflammatory process, but the 17 specific iridoid with anti-inflammatory effect and its mechanism is lack of study. An iridoid 18 compound named scandoside (SCA) was isolated from H. diffusa and its anti-inflammatory effect 19 was investigated in lipopolysaccharide (LPS)-induced RAW 264.7 cells. Its anti-inflammatory 20 mechanism was...
Veronica ciliata Fisch. has traditionally been used in Tibetan medicine for the treatment of hepatitis, cholecystitis, rheumatism, and urticaria. We analyzed the chemical composition of the iridoid glycosides fraction (IGF) isolated from V. ciliata and evaluated the antioxidant and hepatoprotective properties. The IGF was separated by high-speed countercurrent chromatography (HSCCC) and the mai...
Protective effect of Hedyotis diffusa (H. diffusa) Willd against lipopolysaccharide (LPS)-induced renal inflammation was evaluated by the productions of cytokines and chemokine, and the bioactive constituents of H. diffusa were detected by the ultra-fast liquid chromatography-diode array detector-quadrupole-time of flight mass spectrometry (UFLC-DAD-Q-TOF-MS/MS) method. As the results showed, w...
A new iridoid glycoside, 9-epi-6alpha-methoxy geniposidic acid (4), three new hemiterpene glycosides, 3-methylbut-3-enyl 2'-O-(beta-D-glucopyranosyl)-beta-D-glucopyranoside (nonioside K) (6), 3-methylbut-3-enyl 6'-O-(beta-D-xylopyranosyl)-beta-D-glucopyranoside (nonioside L) (8), and 3-methylbut-3-enyl 6'-O-(beta-D-xylofuranosyl)-beta-D-glucopyranoside (nonioside M) (9), and two new saccharide ...
Secoiridoid and iridoid glycosides are the main active components of Gentianaeradix. In this work, one iridoid and three secoiridoid glycosides from Gentianaeradix have been purified by high-speed counter-current chromatography in two runs using different solvent systems. Ethyl acetate-n-butanol-water (2:1:3, v/v/v) was the optimum solvent system to purify ca. 4.36 mg of loganic acid, 3.05 mg o...
