摘要:目的 建立RP-HPLC同時測定射干藥材中芒果苷、射干苷、野鳶尾苷、鳶尾黃素、鳶尾甲黃素B、鳶尾甲黃素A、野鳶尾黃素、白射干素及次野鳶尾黃素共9種成分含量的方法。方法 采用LeapsilTM C18色譜柱(100 mm×2.1 mm,3 ?m),流動相為乙腈-0.1%甲酸水溶液梯度洗脫,檢測波長265 nm,流速0.5 mL/min,柱溫40 ℃。結(jié)果 芒果苷、射干苷、野鳶尾苷、鳶尾黃素、鳶尾甲黃素B、鳶尾甲黃素A、野鳶尾黃素、白射干素、次野鳶尾黃素的線性范圍分別為0.214 0~2.568 ?g(r=0.999 5)、0.437 0~5.244 ?g(r=0.999 3)、0.460 0~5.520 ?g(r=0.999 9)、0.078 40~0.940 8 ?g(r=0.999 6)、0.138 0~1.656 ?g(r=0.999 3)、0.051 00~0.612 0 ?g(r=0.997 5)、0.113 0~1.356 ?g(r=0.999 9)、0.051 63~0.619 6 ?g(r=0.999 8)、0.151 0~1.812 ?g(r=0.999 9),平均加樣回收率分別為97.73%、96.81%、97.78%、97.55%、96.86%、98.60%、97.77%、98.04%、97.89%,RSD分別為0.7%、1.1%、2.3%、2.1%、1.3%、1.4%、2.3%、1.6%、1.9%。應(yīng)用該方法測定了5批射干藥材中9種成分的含量。結(jié)論 該方法準(zhǔn)確、可靠,可為射干藥材的質(zhì)量控制提供參考依據(jù)。

Abstract: Objective To develop an RP-HPLC method for simultaneous determination of mangiferin, tectoridin, iridin, tectorigenin, iristectorigenin B, iristectorigenin A, irigenin, dichotomin and irisflorentin in Belamcandae Rhizoma. Methods Separation was carried out on an LeapsilTM C18 column (100 mm×2.1 mm, 3 ?m) with an isocratic mobile phase consisting of acetonotrile and formic acid at a flow rate of 0.5 mL/min; The detection wavelength was set at 265 nm; the column temperature was 40 ℃. Results The linear ranges of mangiferin, tectoridin, iridin, tectorigenin, iristectorigenin B, iristectorigenin A, irigenin, dichotomin and irisflorentin were 0.214 0– 2.568 ?g (r=0.999 5), 0.437 0–5.244 ?g (r=0.999 3), 0.460 0–5.520 ?g (r=0.999 9), 0.078 40–0.940 8 ?g (r=0.999 6), 0.138 0–1.656 ?g (r=0.999 3), 0.051 00–0.612 0 ?g (r=0.997 5), 0.113 0–1.356 ?g (r=0.999 9), 0.051 63–0.619 6 ?g (r=0.999 8) and 0.151 0–1.812 ?g (r=0.999 9), respectively. The average recoveries were 97.73%, 96.81%, 97.78%, 97.55%, 96.86%, 98.60%, 97.77%, 98.04% and 97.89%, respectively; the relative standard deviations were 0.70%, 1.1%, 2.3%, 2.1%, 1.3%, 1.4%, 2.3%, 1.6% and 1.9%, respectively. This method was used to determine the contents of nine active ingrients in 5 batches of Belamcandae Rhizoma. Conclusion The method is accurate and reliable, which can be used for the quality control of Belamcandae Rhizoma.
