【摘要】:目的利用超高效液相色譜配置二極管陣列檢測器,旨在建立同時(shí)測定黑果腺肋花楸漿果中原花青素B1、原花青素B2、原花青素B4、蘆丁和槲皮素的方法。方法色譜柱為ACQUITY UPLC?HSS T3 C18色譜柱(100 mm×2.1 mm,1.8μm);甲醇-0.03%磷酸水溶液為流動(dòng)相,梯度洗脫;柱溫35℃;體積流量為0.2 m L/min;檢測波長:原花青素B1、原花青素B2和原花青素B4為280 nm,蘆丁和槲皮素為360 nm。結(jié)果原花青素B1、原花青素B2、原花青素B4、蘆丁和槲皮素分別在2.2~44.0μg/m L(r=0.999 2)、50~1 000μg/m L(r=0.999 5)、3.6~54.0μg/m L(r=0.999 2)、7.4~148.0μg/m L(r=0.999 4)和2.1~42.0μg/m L(r=0.999 7)呈良好的線性關(guān)系,平均回收率分別為101.23%、99.64%、102.31%、98.74%和103.53%,RSD分別為2.13%、1.23%、2.89%、2.96%、2.64%。黑果腺肋花楸漿果中原花青素B1、原花青素B2、原花青素B4、蘆丁和槲皮素的平均質(zhì)量分?jǐn)?shù)分別為129.78、3 834.99、196.02、134.40、79.10μg/g。結(jié)論該方法操作簡單、結(jié)果準(zhǔn)確,具有較好的重復(fù)性和穩(wěn)定性,可用于同時(shí)測定黑果腺肋花楸漿果中5種主要有效成分,將為黑果腺肋花楸質(zhì)量控制提供科學(xué)依據(jù)。
