flavan-3-ols isolated from some medicinal plants inhibiting cox-1 and cox-2 catalysed prostaglandin biosynthesis. | extracts from the four plant species atuna racemosa raf. ssp. racemosa, syzygium corynocarpum (a. gray) c. muell., syzygium malaccense (l.) merr. & perry and vantanea peruviana macbr., traditionally used for inflammatory conditions, were fractionated using a cyclooxygenase-1 catalysed prostaglandin biosynthesis in vitro assay. the flavan-3-ol derivatives (+)-catechin, (+)-gallocatechin, 4'-o-me-ent-gallocatechin, ouratea-catechin and ouratea-proanthocynidin a were isolated as active principles. ... | 1998 | 9741297 |
evaluation of some samoan and peruvian medicinal plants by prostaglandin biosynthesis and rat ear oedema assays. | in our ongoing program to find new anti-inflammatory compounds, 58 extracts from 46 different medicinal plant species, used in treatment of inflammatory disorders-38 plants from the traditional medicine of western samoa and eight originating from the indigenous medicine of the shipibo-conibo tribe of peruvian amazonia-ere evaluated. the ability of all extracts to inhibit cyclooxygenase-1 catalysed prostaglandin biosynthesis in vitro was examined. of the plant species tested 14 showed moderate to ... | 1997 | 9234163 |
