The bioassay-directed isolation of Terminalia chebula fruits afforded four human immunodeficiency virus type 1 (HIV-1) integrase inhibitors, gallic acid ( 1) and three galloyl glucoses ( 2 - 4). In addition, four flavonol glycoside gallates ( 5 - 8) from Euphorbia pekinensis containing the galloyl moiety also showed the inhibitory activity at a level comparable to those of 2 - 4.

The leaf extract of E. neriifolia significantly reduced apomorphine-induced stereotypy in mice at all doses (100, 200, 400 mg/kg body weight) in mice and rats and was devoid of catalepsic effect thereby, suggesting specific dopaminergic receptor modulating activity. The extract (400 mg/kg) potentiated pentobarbitone-induced hypnosis. It showed protection against maximal electro-shock-induced convulsion at 400 mg/kg. E. neriifolia leaf extract had anxiolytic action at 400 mg/kg by increasing the percentage of time spent in open arm in elevated plus-maze.

BACKGROUND: A search for inhibitors of multidrug resistance (MDR)-associated protein 1 (MRP1) was performed among the compounds isolated from Euphorbia species, plants traditionally used in folk medicine. MATERIALS AND METHODS: Fifteen compounds with terpenic or phenolic structures (macrocyclic and polycyclic diterpenes, coumarins, stilbenes and flavonoids) were isolated from the methanol extracts of Euphorbia lagascae and Euphorbia tuckeyana or obtained by derivatization.

Euphorbia species are widely distributed plants, many of which are used in folk medicine. Over the past twenty years, they have received considerable phytochemical and biological attention. Their diterpenoid constituents, especially those with abietane, tigliane, ingenane skeletons, are thought to be the main toxicant and bioactive factors. In this work, the utility of (13)C-NMR spectroscopy for the structural elucidation of these compounds is briefly discussed.

OBJECTIVE: To study the antihyperglycemic and antinociceptive activities of methanolic extract of the whole plant of Euphorbia thymifolia L., a plant used in folk medicine of Bangladesh for treatment of diabetes and pain. METHODS: Antihyperglycemic activity studies were conducted in glucose-loaded mice by oral glucose tolerance tests. Mice were given various doses of the extract, followed by glucose (2 g/kg body weight), 1 h after administration of the extract. Serum glucose levels were measured 2 h after glucose administration.

The roots of Euphorbia kansui are considered an important traditional folk medicine. In this study the ethanol extracts of E. kansui were investigated. A new tetracyclic triterpenoid, euphane-3b,20-dihydroxy-24-ene, in addition to five known triterpenoids with euphane skeletons were isolated. Their structures were elucidated on the basis of physical and spectral techniques (1D-, 2D-NMR and MS, respectively).
