Plant latex, the source of natural rubber, has been of interest to mankind for millennia, with much of the research on its rheological (flow) properties focused towards industrial application. However, little is known regarding the rheology of the native material as produced by the plant, a key factor in determining latex's biological functions. In this study, we outline a method for rheologica...

A49-year-oldmale nursery employee (a skilled gardener) was referred by theDepartment of Occupational and Environmental Medicine with a vesicular and scaling hand eczema, primarily on the two first fingers and dorsum of the right hand. The patient had worked as a greenhouse gardener for 33 years, primarily with Euphorbia species, without skin problems. In his trainee years, the patient worked wi...

The antibacterial activities and phytochemical analysis of crude extracts of four indigenous plants (Acorus calamus, Euphorbia hirta, Solanum surattense and Taxus baccata) grown in Garhwal Hills region of western Himalaya, India were tested against pathogenic Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Staphylococcus epidermidis, and Bacillus cereus. Solvent extraction of in...

1. From the latex of two members of the plant family Euphorbiaceae, Hura crepitans L. (sand-box tree) and Euphorbia characias L. (Mediterranean spurge), two lectins were purified by affinity chromatography on acid-treated Sepharose 6B followed by elution with D-galactose. 2. The lectin from E. characias is a single molecular species with Mr 80 000, made up of two identical subunits with Mr 40 0...

AIM Euphorbia hirta is the most widely used plant in the folkloric treatment of dengue in the Philippines. This study documents the anecdotal uses of E. hirta in the treatment of dengue in 3 indigenous communities in Pangasinan from April to June of 2015. MATERIALS AND METHODS The number of use reports pertaining to symptoms of dengue and other diseases were tallied from 82 informants living ...

Eutirucallin is a lectin isolated from the latex of Euphorbia tirucalli, a plant known for its medical properties. The present study explores various characteristics of Eutirucallin including stability, cytotoxicity against tumor cells, antimicrobial and antiparasitic activities. Eutirucallin was stable from 2 to 40 days at 4°C, maintained hemagglutinating activity within a restricted range, an...

THE TITLE COMPOUND [SYSTEMATIC NAME: (2S*,3S*,4R*,5R*,9S*,11S*,15R*)-5,15-diacet-oxy-3-nicotino-yloxy-14-oxolathyra-6(17),12(E)-diene], C(30)H(37)NO(7), was isolated from the seeds of Euphorbia lathyris. The tricyclic diterpenoid molecule contains an 11-membered ring, a five-membered ring exhibiting an envelope conformation and a three-membered ring. The 11-membered ring is cis-fused with the t...

Under the bioassay-guided method, two diterpenes, 3-O-(2",3"-dimethylbutanoyl)-13-O-dodecanoylingenol (1) and 3-O-(2",3"-dimethylbutanoyl)-13-O-decanoylingenol (2) isolated from Euphorbia kansui, showed a pronounced antinematodal activity against the nematode Bursaphelenchus xylophilus at the same minimum effective dose (MED) of 5 microg per cotton ball and still displayed antinematodal activit...

Acetone extract of aerial parts of Euphorbia marschalliana collected from Iran has been subjected to different chromatography techniques for fractionation and purification. The stereo-structures of the myrsinol esters 15-O-acetyl-3-O-propionyl-5-O-butanoyl-7-O-nicotinoylmyrsinol (1) and 15-O-acetyl-3,5-O-dibutanoyl-7-O-nicotinoylmyrsinol (2) have been probed using ROESY spectroscopy and modifie...

The in vitro activity on Leishmania infantum promastigotes and Trypanosoma cruzi epimastigotes of 25 semisynthetic terpenoid derivatives has been evaluated. These compounds were obtained through chemical modifications of the major components of Euphorbia resinifera (alpha-euphol and alpha-euphorbol) and Euphorbia officinarum (obtusifoliol and 31-norlanosterol). Leishmaniasis and Chagas' disease...
