title: Phytochemical study and anti-inflammatory properties of Lampaya hieronymi Schum. ex Moldenke.
abstract: The chemical study of aerial parts of Lampaya hieronymi Schum. ex Moldenke yielded oleanolic acid, epi-oleanolic acid, epi-maslinic acid, 4'7-dimethoxyapigenin, p-hydroxyacetophenone, and p-hydroxyacetophenone-beta-glucoside. In searching for natural products as potential anti-inflammatory agents, all the compounds, except 4'7-dimethoxyapigenin were evaluated in vivo for their ability to inhibit acute inflammation. Our studies demonstrated that p-hydroxyacetophenone and the triterpenes produced protective effects in carrageenan induced paw edema in mouse, at 1-3 h and 3-5 h, respectively, after the injection of carrageenan. These results indicated that their effects might correlate with the release of histamine, serotonin, kinin and prostaglandins.
