Evidence is presented that phorbic acid is formed in the latex producing cell system, rather than in photosynthetic or chlorophyll-free tissues of Euphorbia resinifera Berg. When a branch of the plant was kept first in a (14)CO(2) atmosphere with 12 hr light-dark periods for 2 days and then left under natural conditions in the air outside for at least 2 to 3 days, radioactive phorbic acid was f...

Little is known about the prevalence, diversity, evolutionary processes, genomic structures and population dynamics of viruses in the divergent geminivirus lineage known as the capulaviruses. We determined and analyzed full genome sequences of 13 Euphorbia caput-medusae latent virus (EcmLV) and 26 Alfalfa leaf curl virus (ALCV) isolates, and partial genome sequences of 23 EcmLV and 37 ALCV isol...

Several macrocyclic diterpenes with jatrophane or lathyrane skeletons were isolated from methanol extracts of Hungarian Euphorbia species and evaluated for multidrug resistance (MDR)-reversing activity on a human colon cancer cell line. MDR-reversing activity was tested by using a standard functional assay with Rhodamine 123 as a fluorescent substrate analogue of epirubicin. In the model of com...

Phytochemical investigation of the aerial parts of Euphorbia erythradenia Bioss. (Euphorbiaceae), one of Iranian endemic Euphorbias, with particular attention to triterpene constituents, using methanol solvent extraction was carried out. Five known triterpenes, including four cycloartanes and oleanolic acid, were isolated for the first time and identified using NMR and Mass techniques. Anti HIV...

The roots of Euphorbia kansui are considered an important traditional folk medicine. In this study the ethanol extracts of E. kansui were investigated. A new tetracyclic triterpenoid, euphane-3b,20-dihydroxy-24-ene, in addition to five known triterpenoids with euphane skeletons were isolated. Their structures were elucidated on the basis of physical and spectral techniques (1D-, 2D-NMR and MS, ...

Euphorbia otjipembana was hitherto only known from the type locality within the Kaokoveld Centre of Endemism, northwestern Namibia. Subsequently several additional populations were discovered, allowing for an amplified description of the species and the recognition of two subspecies. Euphorbia otjipembana subsp. okakoraensis, here described as a new subspecies, is only known from a small area w...

R.S. Thorne Cavendish Laboratory, University of Cambridge, UK Abstract I discuss the issue of uncertainties in parton distributions and in the physical quantities which are determined in terms of them. While there has been significant progress on the uncertainties associated with errors on experimental data, there are still outstanding questions. Also, I demonstrate that in many circumstances t...

The plant Dugdhika belongs to the family Euphorbeaceae and is found all over India up to the height of 6000 ft. Various workers have proved it beneficial for the treatment of Bronchial asthma, on the basis of their clinical and experimental studies conducted on the mixture of two plants i.e. Euphorbia thymifolia Linn and Euphorbia prostrate W. Ait, taken by the name of Dugdhika. Again, both the...

The present study deals with the antimicrobial activity and phytochemical screening of the two medicinal plants, Tinospora cordifolia and Euphorbia hirta those are commonly available in India. Results of antimicrobial activity revealed that these medicinal plant extracts were very effective against Serratia marcescens, E. coli, Streptococcus thermophilus, Fusarium oxysporium, Aspergillus niger ...
