One rare flavonoid-diterpene heterodimer, denticulatain C (1), one modified geranyl-type side chain substituted flavonoid, denticulatain D (2) and one geranylated flavonoid, denticulatain E (3), as well as 11 known compounds (4-14) were isolated from the fronds of Macaranga denticulata. Their structures were elucidated on the basis of extensive spectroscopic interpretation. Compounds 4 and 8 in...

The aim of the present study was to evaluate antioxidant, antimicrobial, anti-HIV, and cholinesterase inhibitory activities of aqueous and alcoholic extracts from leaves, stems, and flowers of Euphorbia characias. The extracts showed a high antioxidant activity and were a good source of total polyphenols and flavonoids. Ethanolic extracts from leaves and flowers displayed the highest inhibitory...

BACKGROUND Given its numerous biologically active components, Euphorbiaceae has been found to be a large plant family and polyvalent with quite interesting therapeutic activity that can be studied. MATERIALS AND METHODS The ixodicidal activity of Euphorbia cyparissias extracts was studied in vitro and in vivo. Tested concentrations were 10, 5, 2, 1, 0.5 and 0.25%. RESULTS For the in vitro s...

Euphorbia trigona latex has been used most effectively in the traditional Indian medicinal system of Ayurveda for the treatment of urinary tract infection (UTI). However, various organic and aqueous extracts of its latex were found not to possess any antimicrobial activity against several gram positive and gram negative organisms including Proteus mirabilis and Pseudomonas aeruginosa (selected ...

BACKGROUND A pharmaco-chemical investigation of the Euphorbia cyparissias plant was justified by its known multiple therapeutic valences. Numerous components from extracts and latex of Euphorbiacae were identified, revealing a large plant family with a polyvalent therapeutic activity. MATERIALS AND METHODS The aim of the study was to assess the skin tolerance level to irritation on different ...

There were various problems in the determination of oil acid value of the national standard method, and this paper developed a low cost, simple and effective way to determine the acid value of oil and grease. Furthermore, the esterification of high acid Euphorbia lathyris L. oil (ELO) with methanol could be efficiently catalyzed by hydrochloric acid to produce biodiesel, and the influencing fac...
