Determination of Chlorogenic Acids (CGA) in Coffee Beans using HPLC
نویسندگان
چکیده
Chlorogenic acids (CGA) are the main phenolic compounds in coffee and coffee has one of the highest concentrations of CGA of all plant constituents. In this study, the levels of CGA in certain coffee (Arabica Jimma (ArJM), Arabica Nekemit (ArNK), Arabica Sidamo (ArSD), Arabica Jimma (ArJM) raw, and Arabica Jimma (ArJM) Husk) brands found in Ethiopia were determined using High Performance Liquid Chromatography (HPLC). The levels of CGA in all the coffee brands were found to be within the documented range. The order of CGA concentration (mg/g) in coffee samples was found as follows: ArJM raw > ArJM > ArSD > ArNK > ArJM Husk. Generally, Arebica Jimma raw (46.144 mg/g) has the highest while Arebica Jimma husk (0.981 mg/g) has the least concentration of CGA.

Electrochemical Behavior and Determination of Chlorogenic Acid Based on Multi-Walled Carbon Nanotubes Modified Screen-Printed Electrode
In this paper, the multi-walled carbon nanotubes modified screen-printed electrode (MWCNTs/SPE) was prepared and the MWCNTs/SPE was employed for the electrochemical determination of the antioxidant substance chlorogenic acids (CGAs). A pair of well-defined redox peaks of CGA was observed at the MWCNTs/SPE in 0.10 mol/L acetic acid-sodium acetate buffer (pH 6.2) and the electrode process was ads...

Chlorogenic acid (CGA) is widely distributed in the plant kingdom.For example, green coffee beans contain 6–10% CGA, and a 200-ml cup of coffee may have 20–675 mg CGA, depending on the roasting and brewing conditions [1]. In potato tubers CGA constitutes up to 90% of the total phenolic content [2]. CGAplays an important role in Progr Colloid Polym Sci (2004) 127: 83–88 DOI 10.1007/b98017 Spring...

Coffee is a major source of dietary antioxidants; some are present in the green bean, whereas others are generated during roasting. However, there is no single accepted analytical method for their routine determination. This paper describes the adaption of three complementary assays (Folin-Ciocalteu (FC), ABTS and ORAC) for the routine assessment of antioxidant capacity of beverages, their vali...
متن کاملEffect of simultaneous consumption of milk and coffee on chlorogenic acids' bioavailability in humans.
Different studies have shown that milk may interact with polyphenols and affect their bioavailability in humans. The present study investigated the effect of the simultaneous consumption of coffee and milk on the urinary excretion of chlorogenic acids (CGA) and metabolites. Subjects were submitted to consumption of water, instant coffee (609 mmol of CGA) dissolved in water, and instant coffee d...
