Three new myrsinol diterpenes were isolated from the roots of Euphorbia prolifera. Their structures were elucidated as 2α-O-isobutyryl-3β,5α,7β,10,15β-penta-O-acetyl-14α-O-benzoyl-10,18-dihydromyrsinol (1), 2α-O-isobutyryl-3β-O-propion-yl-5α,7β,10,15β-tetra-O-acetyl-10,18-dihydromyrsinol (2), and 2α,14α-di-O-benzoyl-3β,5α,7β,10,15β-penta-O-acetyl-10,18-dihydromyrsinol (3) on the basis of spectr...

Ten new ingol lathyrane-type diterpenes (1-10) and two known ingenol derivatives (11 and 12) were isolated from the aerial parts of Euphorbia royleana. The structures of 1-10 were elucidated on the basis of spectroscopic methods including 2D NMR analysis, and the structure of compound 1 was confirmed by single-crystal X-ray crystallography. Antiangiogenic effects of all compounds except for 5 w...

The objective of this study was to observe the molluscicidal activities of Euphorbia milli, known as "poysean" in Thailand, against Indoplanorbis exustus. Latex from 12 different E. milii hybrids was screened for its molluscicidal activities. Indoplanorbis exustus were exposed for 24 and 48 hours to the latex at various concentrations ranging from 6 to 25 ppm and mortality rates were recorded. ...

in the present work, a new branch of biotechnological advantage of the latex of an endemic perennial plant, euphorbia microsciadia has been introduced. a novel cysteine protease, designated as microsciadin, was purified from the latex of euphorbia microsciadia by a combination of sequential usage of sp-sepharose fast flow column in two different phs and a final gel filtration chromatography. mi...

Crassulacean acid metabolism (CAM) occurs in many Euphorbiaceae, particularly Euphorbia, a genus with C3 and C4 species as well. With the aim of contributing to our knowledge of the evolution of CAM in this genus, this study examined the possible occurrence of CAM in Euphorbia milii, a species with leaf succulence and drought tolerance suggestive of this carbon fixation pathway. Leaf anatomy co...

Several plants are used for their decorative effect during winter holidays. This review explores the toxic reputation and proposed management for exposures to several of those, namely poinsettia (Euphorbia pulcherrima), English holly (Ilex aquifolium), American holly (Ilex opaca), bittersweet (Solanum dulcamara), Jerusalem cherry (Solanum pseudocapsicum), American mistletoe (Phoradendron seroti...
