目的 建立同時(shí)測(cè)定六味地黃膠囊中毛蕊花糖苷、馬錢(qián)苷、芍藥苷和丹皮酚4種成分含量的高效液相色譜（HPLC）測(cè)定方法。方法 應(yīng)用HPLC-梯度洗脫法，采用Kromasil C₁₈（250 mm×4.6 mm，5 μm）色譜柱，以1%冰醋酸為流動(dòng)相A，乙腈為流動(dòng)相B進(jìn)行梯度洗脫，體積流量為1.0 mL/min，檢測(cè)波長(zhǎng)為230 nm。結(jié)果 毛蕊花糖苷、馬錢(qián)苷、丹皮酚和芍藥苷測(cè)定濃度的線性范圍分別為6～60、15～150、50～500 μg/mL和5～50 μg/mL，r值均大于0.999，平均加樣回收率分別為98.3%、99.3%、99.0%和99.0%，相對(duì)標(biāo)準(zhǔn)偏差（RSD）值均小于0.9%（n=9）。結(jié)論 該實(shí)驗(yàn)方法簡(jiǎn)便、結(jié)果準(zhǔn)確，可有效地用于六味地黃膠囊的質(zhì)量控制。

Objective An HPLC method was established for determining four constituents (verbascoside, loganin, paeoniflorin, and paeonolum ) in Liuwei Dihuang Capsule. Methods HPLC-gradient elution method was applied. The column was Kromasil C₁₈ (250 mm × 4.6 mm, 5 μm). The mobile phase was 1% acetic acid solution (A) and acetonitrile (B). The detection wavelength was set at 245 nm. Results The linear range of density was 6—60 μg/mL for verbascoside, 15—150 μg/mL for loganin, 50—500 μg/mL for paeonolum, and 5—50 μg/mL for paeoniflorin, respectively. The correlation coefficient of all curves were better than 0.999. The average recoveries of four analytes were 98.3% for verbascoside, 99.3% for loganin, 99.0% for paeonolum, and 99.0% for paeoniflorin, and the RSD values were less than 0.9% (n = 9). Conclusion The developed HPLC method could be used for the quality control of Liuwei Dihuang Capsule.
