During the study on newly collected and herbarium specimens belonging to the genus Euphorbia, three species, namely, E. gorenfloti, E. cheirolepioides and E. splendida were found to be synonymous with E. chamaepeplus, E. grossheimii and E. decipiens, respectively. Euphorbia sahendi as an interesting and rare species has been recognized after long time again among my material and Euphorbia delto...

BACKGROUND The use of plants in the prevention and treatment of disease is age-old practice. The aveloz (Euphorbia tirucalli) is a plant native of Africa and has been associated with antimicrobial, antiulcers, anticarcinogenic, antiviral, healing, anti-helminthic, antisiphilitic effects. AIM To analyze the effect of the crude extract of Euphorbia tirucalli L. in the stomach healing process of...

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 ...

Anastrepha tehuacana, a new species of Tephritidae (Diptera) from Tehuacán, Puebla, Mexico reared from seeds of Euphorbia tehuacana (Brandegee) V.W. Steinm. (Euphorbiaceae), is described and illustrated. Its probable relationship to A. relicta Hernández-Ortiz is discussed.

Euphorbia wallichii of the family Euphorbiaceae yielded a new rearranged pentacyclic triterpene of the multiflorane class which we have named spirowallichiione. The structure of this natural spirocompound was elucidated with the aid of modern spectroscopic techniques, including 2D-NMR.
