Five ingenane compounds, 1-5, kansuinins A and B, isolated from Euphorbia kansui, and their derivatives 7 and 9 were tested for termiticidal activity against the Japanese termite, Reticulitermes speratus. At 72 hours after treatment, the ingenane compounds 1 to 5 caused 100% mortality in R. speratus at 50, 25 and 12.5 microg/disk, respectively, except for compound 1, which gave a mortality rate...

he present study was aimed at assessing the antimicrobial potential of various extracts of Euphorbia thymifolia against human pathogenic strains of Salmonella typhimurium and Shigella boydii. The antibacterial activity was determined by agar disc diffusion and broth microdilution techniques. The results showed that the growth of the organisms were inhibited by both acetone and hexane extracts o...

Hepatic diseases are serious health issues as various pharmaceuticals, xenobiotics, environmental/chemical pollutants, some natural products and dietary supplements when used in overdose have tendency to cause hepatotoxicity. Present study was aimed at investigating hepatoprotective activity of aqueous methanolic extract of Euphorbia prostrata against paracetamol and carbon tetrachloride induce...

Three compounds, 20-O-acetyl-[3-O-(2'E,4'Z)-decadienoyl]-ingenol (1), 20-O-acetyl-[5-O-(2'E,4'Z)-decadienoyl]-ingenol (2) and 3-O-(2'E,4'Z)-decadienoylingenol (3), were isolated from Euphorbia kansui under the bioassay-guided method. Each compound showed the same antinematodal activity against the nematode, Bursaphelenchus xylophilus, at a minimum effective dose (MED) of 5 microg/cotton ball.

Seven new carolignans, including two pairs of enantiomers (±)-erythro-7'-methylcarolignan E (1a/1b) and (±)-threo-7'-methylcarolignan E (2a/2b), (+)-threo-carolignan E (3a), (+)-erythro-carolignan E (4a), and (-)-erythro-carolignan Z (5), together with four known lignans (3b, 4b, 6, and 7) and six polyphenols (8-13) were isolated from the aerial parts of Euphorbia sikkimensis. The structures of...

The mortality caused to the snail Bulinus wrighti (The snail vector of urinary schistosomiasis) by different extracts of two species of plants belonging to the family Euphorbiaceae has been investigated. It was found that very low concentrations of fresh leaf extracts were effective in killing the snail. The LC50 of methanol and acetone extracts for Euphorbia schimperiana and Euphorbia heliosco...

Parikh College of Commerce, Palanpur (Gujarat) India Abstract This study investigated the allelopathic effects of various weed (Euphorbia thiamifolia L.) plant parts on pigeon pea germination and seedling growth. Aqueous extracts of Euphorbia thiamifoli...

The use of plant extract as poisons for hunting and fishing is common among fishermen of various countries. Fish poisons from plants are also known as piscicides or inchthyotoxins. Several plant species are known to possess bioactive compounds that are toxic to fish. The piscicidal activity of methanolic latex extracts of Euphorbia antiquorum plant belonging to Family: Euphorbiaceae against Poe...

In the family of Euphorbiaceae, the genera Euphorbia and Sapium are known to contain essentially latex-bearing species. In the present study, the latex of Euphorbia selloi (Klotzsch & Garcke) Boiss., Euphorbia papillosa A.St.-Hil., and Sapium glandulosum (L.) Morong, plants native from Brazil, were examined concerning proteolytic activity. All studied species have proteins with significant prot...
