pubmed-article:16972202 | pubmed:abstractText | Two new phenolic glycosides 1 and 2 were isolated from the barks of Hydnocarpus annamensis, along with eighteen known compounds. The structures of all compounds were deduced using spectroscopic methods. Anti-inflammatory and anti-oxidation activities were evaluated. Among the isolates, compounds 1, 5, 15 and 17 exhibited COX-2 inhibitory activities, with an inhibitory rate of 60.3 - 63.4 % at 10 microM. Compounds 7, 12, 13 and 20 showed anti-oxidation capacities in the DPPH free-radical assay, with a scavenging effect of 60.9 - 69.4 % at 50 microM, and 18.5 - 34.6 % at 10 microM. | lld:pubmed |
