摘要

Abstract > Lignans are polyphenolic compounds that are considered phytoestrogens for their plant origins, and they possess different biological activities. Three different extraction methods, ie, “dilute and shoot”, acidic hydrolysis, and enzymatic digestion, have been compared for extracting lignans (secoisolariciresinol (SECO), matairesinol (MAT), and lariciresinol (LARI)) from espresso coffee (EC) by using high‐performance liquid chromatography (HPLC) tandem mass spectrometry (MS/MS). The best recovery values (SECO: 97%, LARI: 98%, and MAT: 93%) were obtained by using enzymatic hydrolysis with Clara‐Diastase at 10% ( w / v ), keeping the sample at 37°C for 3?hours. For this reason, this method has been chosen and then applied to quantify lignans in 9 different EC samples from 5 different geographical origins (Brazil, Colombia, El Salvador, Ethiopia, and India). Secoisolariciresinol and LARI were found in all EC samples from 27.9 to 52.0?μg?L ?1 and from 5.3 to 27.8?μg?L ?1 respectively, contrary to MAT that it was not possible to detect it in each type of coffee. This method confirms the high specificity and sensitivity of MS/MS system for detecting bioactives in complex matrix such as coffee. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs"

lignans是被认为是植物起源的多酚化合物,它们具有不同的生物活性。已经比较了从浓缩咖啡(EC)的浓缩咖啡(EC)中提取木质素(Secoisolaricirachol(Secoisolaricirsinol(Seco),MataIrsinol(Seco),Matairesinol(Seco),Lariciresinol(Lari))进行酸性水解和酶消化的三种不同的提取方法,即“稀释和芽”,酸性水解和酶消化。使用高效液相色谱(HPLC)串联质谱(MS / MS)。通过使用酶水解在10%( W </ i> / v </ i>),将样品保持在37°C 3.小时。因此,已选择该方法,然后应用于从5种不同地理起源(巴西,哥伦比亚,萨尔瓦多,埃塞俄比亚和印度)的9种不同的EC样品中量化Lignans。在所有EC样品中发现SecoIsolariciresinol和Lari分别从27.9至52.0Ω·0≤μgΔ1 1和5.3〜27.8Ω·μgΔ1?1 </
