Determination of the flavonoid components of cashew apple (Anacardium occidentale) by LC-DAD-ESI/MS

Abstract

Liquid chromatography, with diode array detection and electrospray ionization mass spectrometry (LC-DAD-ESI/MS), was used to identify and quantify flavonoids in cashew apple. One anthocyanin and thirteen glycosylated flavonols were detected in a methanol-water extract. Among them, the 3--galactoside, 3--glucoside, 3--rhamnoside, 3--xylopyranoside, 3--arabinopyranoside and 3--arabinofuranoside of quercetin and myricetin, as well as kaempferol 3--glucoside were identified by direct comparison with standards or positively identified flavonoids in cranberry. The anthocyanin was the 3--hexoside of methyl-cyanidin. Trace amounts of delphinidin and rhamnetin were detected in the hydrolyzed extract, suggesting their glycosides were present, but undetectable, in the original extract. The concentrations of the 14 flavonoids in the tested sample were determined. This is the first report of these flavonoids in cashew apple.

Effect of treatment with adsorbent resin on the volatile profile and physicochemical characteristics of clarified cashew apple juice

“…The clarified cashew apple juice can be used to improve nutritional characteristics of mixed drinks by the supplementation of nutrients, such as vitamin C and carotenoids (ASSUNÇÃO;MERCADANTE, 2003;ABREU et al, 2009), sugars (SILVA;RABELO;RODRIGUES, 2012), flavonol glucosides (BRITO et al, 2007;MICHODJEHOUN-MESTRES et al, 2009a), anacardic acids (KUBO et al, 2006;TREVISAN et al, 2006) phenolic acids, and prodelphinidins (MICHODJEHOUN-MESTRES et al, 2009b, c). Moreover, some studies show the functional properties of the cashew apple, such as prevention of acute gastritis caused by Helicobacter pylori (KUBO; LEE; KUBO, 1999) and antioxidant activity (ABREU et al, 2009;LUZIA;JORGE, 2011).…”

Validation of the Analytical Method for the Determination of Flavonoids in Broccoli

“…Retention times for quercetin and kaempferol in samples were 4.834 ± 0.009 min and 7.721 ± 0.011 min, respectively. Quercetin and kaempferol showed lower retention times than those generally reported in the literature (Merken & Beecher 2000, Schieber et al 2001, Sousa de Brito et al 2007). …”
