Structure elucidation and chemistry of novel diterpenoids from Euphorbia plants of Iran
Plants of the genus Euphorbia have been investigated for different bioactive natural products. I have isolated several new and bioactive diterpenoids from different species of Euphorbia of Iran with myrsinane type skeleton. The structure of the compounds was determined using high resolution mass spectroscopy, 1 D and 2 D NMR spectral data. The stereochemistry of the diterpenoids was determined ...

متن کاملBioactive Segetane, Ingenane, and Jatrophane Diterpenes from Euphorbia taurinensis.
A novel segetane (1: ) and jatrophane diterpene (2: ), together with five known diterpenoids possessing segetane (3: ), jatrophane (4: ), and ingenane skeletons (5 - 7: ), were isolated from the methanol extract of Euphorbia taurinensis All. The structure elucidation of the compounds was performed by means of extensive spectroscopic analysis, including HRESIMS and 1D (1H, J-modulated spin-echo ...

Uromyces scutellatus as a keystone species affecting Euphorbia spp. in Europe as shown by effects on density in the field
Nearest neighbor spatial analysis was used to assess the effect of systemic rust caused by Uromyces scutellatus on stand density of Euphorbia esula/virgata , a highly invasive deep-rooted perennial weed of rangelands and natural areas in North America. ANOVA applied to nearest neighbor measurements within four pairs of stands in close proximity, with and without rust, in Hungary and Austria ind...
