First Report of Nigrospora sphaerica Causing Leaf Spot on Watermelon (Citrullus lanatus) in Malaysia

First report on laxative activity of Citrullus lanatus

This study was aimed to assess the possible laxative effect of aqueous fruit pulp extract of Citrullus lanatus in albino’s Wistar rats. Rats were divided in 5 groups of 6 animals each, first group as control, second group served as standard (sodium picosulfate) while group 3, 4 and 5 were treated with fruit pulp aqueous fruit pulp extract of Citrullus lanatus at doses of 250, 500 and 1000 mg/kg...

Lycopene and Citrulline Contents in Watermelon (Citrullus lanatus)

Lycopene and citrulline contents of 9 diploids (2X) and their artificially induced autotetraploids (4X) and autotriploids (3X) were determined in mature fruit. Changes in lycopene and citrulline during fruit development was studied using fruit of variety XYXA with three different ploidy levels from 15 to 40 days after pollination (DAP). Polyploids, especially triploids, had higher levels of lyc...

Origin and emergence of the sweet dessert watermelon, Citrullus lanatus.

BACKGROUND AND AIMS Watermelons, Citrullus species (Cucurbitaceae), are native to Africa and have been cultivated since ancient times. The fruit flesh of wild watermelons is watery, but typically hard-textured, pale-coloured and bland or bitter. The familiar sweet dessert watermelons, C. lanatus, featuring non-bitter, tender, well-coloured flesh, have a narrow genetic base, suggesting that they...

Recombinant Watermelon (Citrullus Lanatus) Hydroperoxide Lyase and Uses Thereof

First report on a novel Nigrospora sphaerica isolated from Catharanthus roseus plant with anticarcinogenic properties

This paper reports on the vinca alkaloid produced by a novel Nigrospora sphaerica isolated from Catharanthus roseus. Through liquid chromatography-mass spectrometry (LCMS), only the crude mycelia extract of this fungus was positive for determination of vinblastine. This vinca alkaloid was then purified by using high-performance liquid chromatography (HPLC) and tested for cytotoxicity activity u...
