Identification by RP-HPLC-DAD, FTIR, TGA and FESEM-EDAX of natural pigments prepared from Datisca cannabina L

Kaempferol mediated synthesis of gold nanoparticles and their cytotoxic effects on MCF-7 cancer cell line

“…The weight loss after decomposition is observed to be 11.8 % which indicates the amount of kaempferol present in k-AuNPs. Similar degradation has been reported for the hemp (Datisca cannabina L) plant through TGA which contains kaempferol and also for pure quercetin which belongs to the same flavonol family as that of kaempferol [46,47].…”

Improvement of submerged culture conditions to produce colorants by Penicillium purpurogenum

“…Furthermore, there is a growing demand for ecofriendly/non-toxic colorants, specifically for health sensitive applications, such as the coloration of food and dyeing of children’s fabrics and leather garments (Santos-Ebinuma et al , 2013b). Natural colorants have been extracted from natural sources, such as plant and insect tissues (Unagul et al , 2005; Boo et al , 2012; Deveoglu et al , 2012), but also these compounds can be produced by microorganisms (Cho et al , 2002; Jiang et al , 2005; Yang et al , 2007; Méndez et al , 2011). The production by the latter is very interesting to industries because microorganisms can grow rapidly and achieve high productivity with a product available throughout the year (Jiang et al , 2005; Méndez et al , 2011).…”

A fluorescent sensor based on quinazoline ketone derivatives for selectivity of Fe3+

“…Therefore, QKDs are considered a candidate for heavy metal ion recognition. The 4(3 H)-quinazoline ketone compound is a kind of nitrogen heterocyclic compound with good physiological activities, especially in antitumor [7], anti-inflammatory [8], antihypertensive [9] and sterilisation [10], and it has always been a focus in the study of medicinal chemistry. In addition, quinazoline ketone itself also has long fluorescence wavelength and good light stability, which makes a good chromophore in chemical sensor research.…”
