Stilbenic Profile of Cocoa Liquors from Different Origins Determined by RP-HPLC-APCI(+)-MS/MS. Detection of a New Resveratrol Hexoside

Abstract: trans-Resveratrol and trans-piceid were recently discovered in chocolate. In the present work, both were quantified by RP-HPLC-APCI(+)-MS/MS in 22 cocoa liquors from 11 different countries. A very large range of concentrations was observed for trans-piceid. The most concentrated sample (Arriba 06) reached 0.4 and 2.6 mg/kg of trans-resveratrol and trans-piceid, respectively, but in other cultivars stilbene levels were five times lower. Neither cis-resveratrol nor cis-piceid was found in cocoa liquors. An unkno… Show more

“…From a functional point of view, cocoa has been considered an important source of different bioactive compounds. The more important groups of compounds present in cacao are flavonoids, mainly flavan-3-ols, phenolic acids, methylxanthines, peptides, N -phenylpropenoyl-L-amino acids, and stilbenes [5,12,13,14,15,16,17,18,19,20].…”

“…Figura 2 -Principais compostos fenólicos encontrados em cacau (WOLLGAST, 2004) Dentre outros compostos já relatados em cacau estão ácidos hidroxibenzóicos (gálico, siríngico, protocatequínico, vanilínico), ácidos hidroxicinâmicos e análogos (caféico, ferúlico, cumárico, clovamida), flavonóis (quercitina), flavonas (luteolina, apigenina) e flavononas (naringenina) (BORCHERS et al, 2000;JERKOVIC et al, 2010). Em 2006, foi relatada pela primeira vez a ocorrência do estilbeno resveratrol por Counet, Callemien e Collin.…”

“…É importante salientar que ocorre grande variação na produção de compostos secundários pelas plantas, sendo esta produção relacionada tanto a fatores genéticos quanto ambientais. Assim, genes responsáveis pela biossíntese de compostos secundários, como o resveratrol, podem ser ativados em casos de infecções por microrganismos ou pragas, solo pobre em nutrientes, clima, exposição à radiação UV, dentre diversos outros fatores (HERAS, 1998;JERKOVIC et al, 2010). Hurst et al (2008) encontraram 1,85 ±0,43 µg.g -1 para cacau em pó e 0,35 ±0,08 µg.g -1 para chocolates amargos.…”
