ABSTRACT
Objective:
To study the chemical constituents of Ostryopsis nobilis and their anti-oxidant activities.Methods:
The chemical constituents were isolated and purified by various column chromatographic methods. Their structures were identified by physicochemical properties and spectral analyses.Results:
Twenty-three compounds were isolated from the 95% ethanol extract and identified as loliolide (1), maslinic acid (2), vanillic acid (3), 3β-(3, 4-dihydroxycinnamoyl)-erythrodiol (4), dammarenediol II 3-caffeate (5), pinoresinol (6), quercetin (7), daucosterol (8), kaempferol (9), 3, 5-dihydroxy-1, 7-bis (4H-hydroxyphenyl) heptane (10), alnusdiol (11), casuarinondiol (12), quercetin-3-O-α-L-arabinoside (13), isoquercetin (14), 2, 3-dihydroxylbenzoic acid (15), isoquercetin-6″-butyl acetate (16), isoquercetin-6″-benzoate (17), 4″-trans-p-coumaroyl-kaempferol-3-O-α-L-rhamnoside (18), 4″-cis-p-coumaroyl-kaempferol-3-O-α-L-rhamnoside (19), maslinic acid-28-O-β-D-glucoside (20), gallic acid (21), betulatetraol (22), and L-chiroinositol (23).Conclusion:
All the compounds are isolated from the plants in this genus for the first time. Diarylheptanoid compounds and other ten monomer compounds exhibit the good scavenging activities against 2, 2-diphenyl-1-picryhydrazyl (DPPH), and O. nobilis extracts show moderate anti-oxidant effects.
