چکیده

A new phenolic compound, named 3-geranyl-2,5-dihydroxy-benzaldehyde (1), together with seven known chalone derivatives (2–8) has been isolated from the seeds of Celosia cristata L. Their chemical structures have been elucidated by spectroscopic analysis. All these compounds (1–8) were isolated from C. cristata for the

Phenolic constituents of Celosia cristata L. susceptible to spinach root rot pathogen Aphanomyces cochlioides.

Cochliophilin A (5-hydroxy-6,7-methylenedioxyflavone, 1), known as a host-specific attractant towards the zoospores of Aphanomyces cochlioides, a cause of root rot and damping-off diseases of Chenopodiaceae, was found in the Amaranthaceae plant, Celosia cristata, that is susceptible to the pathogen. The content of 1 in Celosia seedlings was quantified as 1.4 microg/g fresh weight. A new isoflav...

Depurination of ribosomal RNA and inhibition of viral RNA translation by an antiviral protein of Celosia cristata.

An antiviral protein (25 kD) isolated from leaves of Celosia cristata (CCP 25) was tested for depurination study on ribosomal RNA from yeast. Ribosomal RNA yielded 360 nucleotide base fragment after treatment with CCP 25 indicating that CCP 25 was a ribosome inactivating protein. CCP 25 also inhibited translation of brome mosaic virus (BMV) and pokeweed mosaic virus (PMV) RNAs in rabbit reticul...

Identification of a partial mRNA containing UL 31 viral protein domain from Celosia cristata expressed sequences

A partial mRNA sequence was identified from Celosia cristata purified leaf mRNA population at the early vegetative stage. Based on its deduced amino acid sequence analysis, it was predicted to encode a homologue of Herpes UL31 protein superfamily in test plant. The bacterial origin of the isolated fragment was eliminated on the basis of some experimental evidences. Since the cloned mRNA fragmen...

Triterpenoid saponins from the seeds of Celosia argentea and their anti-inflammatory and antitumor activities.

Three new triterpenoid saponins, named celosin E (1), celosin F (2) and celosin G (3), together with a known compound cristatain (4), were isolated from the seeds of Celosia argentea L. (Amaranthaceae). All the isolated compounds were obtained for the first time from this plant. The structures of new compounds were characterized on the basis of extensive NMR experiments and mass spectrometry da...

The Growth and Duration of Life of Celosia Cristata Seedlings at Different Temperatures

Daily measurements of hypocotyl length were made on Celosia cristata seedlings cultured in darkness under aseptic conditions at six constant temperatures between 14.5 degrees and 40.5 degrees C. At 40.5 degrees roots did not penetrate the agar and only the hypocotyls that were supported by the wall of the test tube could be measured. The growth curves were of the generalized logistic type, but ...
