Cucurbitane-type triterpenoids from the fruits of Citrullus colocynthis
Fitoterapia, 2023A phytochemical investigation of the fruits of Citrullus colocynthis resulted in the isolation of 21 structurally diverse cucurbitane triterpenoids, including 9 previously undescribed ones, colocynins A-I (1-9). Their absolute configurations were elucidated by means of quantum chemical electronic circular dichroism (ECD) calculations, CD exciton ...

Cucurbitacin glucosides fromCitrullus colocynthis
Natural Product Research, 2006A new cucurbitacin glucoside 2-O-beta-D-glucopyranosyl-16alpha-20R-dihydroxy-cucurbita-1,5,23E,25(26)-tetraen-3,11,22-trione (1) has been isolated from the methanolic extract of the fruits of Citrulluscolocynthis. The structure has been assigned on the basis of spectral analysis including 1D and 2D NMR techniques.

Phylogeography of the Bitter Apple, Citrullus Colocynthis
Genetic Resources and Crop Evolution, 2006Citrullus colocynthis is a desert plant with a rich history as an important medicinal plant and as a source of valuable oil. Its small seeds appear in several early Egyptian, Lybian and Near Eastern sites from about 4000 BC. Sequence information deduced from several polymorphic intergenic cpDNA regions and a relatively large intron (0.6 kb) at the ...

The effect of Citrullus colocynthis on sheep.
Veterinary and human toxicology, 1985Fresh Citrullus colocynthis fruits and leaves were fed to ten sheep at daily doses ranging from 0.25 to 10 g/kg. The sheep showed signs of poisoning and died from 4 hours to 25 days after dosing. The clinical signs of diarrhea, anorexia, dyspnea and loss of condition were well correlated with the pathological findings.

Cucurbitacin glycosides from Citrullus colocynthis
Phytochemistry, 1989Abstract The chloroform extract of Citrullus colocynthis yielded four cucurbitacin glycosides which were identified spectroscopically as 2- O -β- d -glucopyranosyl-cucurbitacin I, 2- O -β- d -glucopyranosyl-cucurbitacin E, 2- O -β- d -glucopyranosyl-cucurbitacin L and the novel glycoside, 2- O -β- d -glucopyranosyl-(22–27)-hexanorcucurbitacin I ...

Constituents of Citrullus colocynthis (L.) Schrad.
Phytochemistry, 1964Abstract The chemical constituents of Citrullus colocynthis (L.) Schrad. have been found to consist mainly of glycosides which upon enzymatic hydrolysis yield elaterin (cucurbitacin E), elatericin B (cucurbitacin I) and dihydroelatericin B (cucurbitacin L).
