“…Chlorogenic acid (CGA) is the major molecule of polyphenolic compounds in SFM as demonstrated by many researchers (Leung et al, 1981;Pedrosa et al, 2000). Sabir et al (1974), Lusas (1985) and Salem (1990) reported that the percent of CGA is 70% of total phenolic constituents in SFM. Irrespective of CGA, SFM contains other phenolic compounds such as caffeic, rosmarinic and ferulic acids, as well as myricetin and rutin, all these compounds present in quantities of less than 0.15 ppm.…”

| The benificial application of untraditional feedstuffs such as sunflower meal (SFM) in animal and poultry nutrition in developing countries has received considerable attention. SFM is a by-product of sunflower oil industry, and has been increasingly added to animal and birds diets. Moreover, SFM is potentially one of the most important protein source in the world. Nowadays, it is well known that feed represents the main cost of animal and poultry production and accounts about 75% of the total cost. The increasing feed ingredients price of poultry nutrition caused to look closely at agricultural by-products which are less cost than traditional ingredients. Thus, the waste residues of crops, vegetables and fruits after harvesting and processing could be used as sources of protein, energy and other nutrients in feeding animals and poultry. Reports from variuos laboratories on the using SFM as feed ingredient for poultry are discussed in this review. Based on the findings presented, SFM is an acceptable feed componentof poultry rations and can be fed at 25% in broiler and 20% in layer diets. However, replacement of soybean meal (SBM) with SFM may affect dietary inclusions of essential amino acids, and use of synthetic lysine may need to be increased. The high levels of SFM in poultry diets can be used successfully with appropriate diet formulation adjustments for energy and amino acids particularly lysine and methionine. This compilation with its valubale information would be beneficial for researchers, chemists, feed and food industry, and certainly could help to promote the usage of SFM in poultry production.

“…Sunflower kernels and hulls contain phenolic compounds, including chlorogenic and caffeic acids, which are easily oxidised during common processing causing green to brown discoloration in protein isolates and/or concentrates (Sabir et al, 1974a;Sabir et al, 1974b). These compounds have been studied both for their additive/synergistic effect on carcinogenesis and their anti-carcinogenic properties (Hirose et al, 1997).…”

“…Chlorogenic acid is the principal colour-forming constituent of sunflower kernels but small quantities of caffeic acid and other phenolic compounds are also present. These compounds bind to proteins and their removal from sunflower products is difficult (Sabir et al, 1974a and1974b;Saeed and Cheryan, 1989).…”

Recebido em 11/12/02; aceito em 1/4/04; publicado na web em 27/05/04 ANALYTICAL METHODS FOR CHLOROGENIC ACID. This paper describes the analytical methods for determination of total chlorogenic acid (CGA) and their individual isomers. Spectrofotometric methods are adequate for total CGA analysis in green coffee but they can provide inflated results for coffee products. High pressure liquid chromatography (HPLC) with gel permeation column and ultraviolet (UV) monitoring is adequate for the simultaneous analysis of total CGA, alkaloids and sugars in coffee products. HPLC-UV-reversed phase is a simple, rapid and precise method for the determination of the individual isomers of CGA. Gas chromatography (GC) also is applied to the analysis of the individual isomers but phenolic acids need to be derivatized before analysis. Both HPLC-and GC-mass spectrometry provide an unequivocal identification of the individual isomers. The capillary electrophoresis method is simple, rapid and adequate to the simultaneous analysis of polyphenols and xanthines. Advantages and limitations of each method are discussed throughout the text.Keywords: total chlorogenic acid; individual isomers; analytical methods. INTRODUÇÃOO termo ácido clorogênico (ACG) parece ter sido introduzido em 1846 por Payen 1 para designar um composto fenólico com função ácida, de estrutura ainda desconhecida, que conferia cor verde ao meio aquoso quando em meio levemente alcalino e exposto ao ar. Esse ácido foi isolado em 1907 2 na forma de um complexo cristalino, denominado clorogenato de cafeína, a partir do qual se preparou um ácido puro. A estrutura química para este composto foi estabelecida por Fischer 3 como ácido 3-cafeoilquínico (atualmente conhecido como ácido 5-cafeoilquínico). Mais tarde, outros compostos fenólicos ácidos foram isolados, caracterizados quanto à estrutura química e agrupados na mesma família 4 . Atualmente, o termo ACG é usado para designar uma família de ésteres formados pela esterificação de um ou mais derivados do ácido trans-cinâmico (Figura 1a) com o ácido quínico (ácido 1L-1(OH),3,4,5-tetra-hidroxiciclohexanóico); este último tem hidroxilas na posição axial nos carbonos 1 e 3 e hidroxilas equatoriais nos carbonos 4 e 5 (Figura 1b). Os isômeros cis dos derivados do ácido cinâmico já foram detectados em produtos processados, porém não têm sido detectados naqueles in natura 5. Esses compostos fenólicos podem ser subdivididos pela identidade do derivado do ácido cinâmico, número e posição dos resíduos acila. Os grupos majoritários (Figura 1e), encontrados na natureza, estão relacionados abaixo: 1-éster do ácido cafêico (Figura 1c) com o ácido quínico (ácido cafeoilquínico -ACQ) (isômeros 3-, 4-, 5-) 2-éster de dois resíduos do ácido cafêico com um de ácido quínico (ácido dicafeoilquínico -diACQ) (isômeros 3,4-, 3,5-, 4,5-) 3-éster do ácido ferúlico (Figura 1d) com o ácido quínico (ácido feruloilquínico -AFQ) (isômeros 3-, 4-, 5-). O grupo mais abundante na natureza é o ACQ e, portanto, existe uma extensa literatura a seu respeito. Em ...
