目的:建立同时测定民族药芒萁中芦丁、槲皮苷、山柰酚-3-O-α-L-鼠李糖苷、槲皮素和山柰酚的RP-HPLC测定方法。方法:采用PntulipsTMBP-C18色谱柱(4.6 mm×250 mm,5μm),以乙腈(A)-0.5%磷酸(B)为流动相,梯度洗脱(0~10 min,15%A;10~11 min,15%A→25%A;11~20 min,25%A→55%A;20~30 min,55%A→15%A),流速1 m L·min~(-1),检测波长360 nm,柱温30℃。结果:在选定的实验条件下,芦丁、槲皮苷、山柰酚-3-O-α-L-鼠李糖苷、槲皮素和山柰酚得到良好的分离,质量浓度分别在77.2~694.8μg(r=0.999 8,n=6)、43.6~392.4μg(r=0.999 9,n=6)、288.0~2 592.0μg(r=0.999 9,n=6)、38.4~354.6μg(r=0.999 9,n=6)和43.8~394.2μg(r=0.999 2,n=6)范围内呈良好线性关系,平均回收率分别为97.6%(RSD=1.94%)、98.6%(RSD=1.11%)、96.9%(RSD=1.22%)、97.1%(RSD=1.97%)和95.3%(RSD=2.01%)。4个不同产地芒萁的含量测定结果表明,山柰酚-3-O-α-L-鼠李糖苷为芒萁的主要成分,其次为槲皮苷。不同产地的芒萁中5种成分的含量差异变化不大,芦丁、槲皮苷、山柰酚-3-O-α-L-鼠李糖苷、槲皮素和山柰酚的含量分别为0.109~0.176、0.584~0.686、2.416~2.627、0.088~0.131和0.018~0.031 mg·g~(-1)。结论:该方法简单易行,高效快速,可用于民族药芒萁的品质评价及质量控制。
OBJECTIVE: To establish a RP-HPLC method for the simultaneous determination of rutin, quercitrin, kaempferol-3-O-α-L-rhamnoside, quercetin and kaempferol in the medicinal herb Manglietia. Methods: The mobile phase was eluted with gradient elution (0-10 min, 15% A; 10-11, using Pntulips TMBP-C18 column (4.6 mm × 250 mm, min, 15% A → 25% A, 11-20 min, 25% A → 55% A, 20-30 min, 55% A → 15% A) at a flow rate of 1 m L · min -1 Wavelength 360 nm, column temperature 30 ℃. Results: Under the selected experimental conditions, rutin, quercitrin, kaempferol-3-O-α-L-rhamnoside, quercetin and kaempferol were separated well with mass concentrations of 77.2 (R = 0.999 9, n = 6), 43.6-392.4 μg (r = 0.999 9, n = 6), 288.0-2 592.0 μg (r = 0.999 9, n = 6) and 43.8 ~ 394.2μg (r = 0.999 2, n = 6). The average recoveries were 97.6% (RSD = 1.94%) and 98.6% (RSD = 1.11%), 96.9% (RSD = 1.22%), 97.1% (RSD = 1.97%) and 95.3% (RSD = 2.01%). The results of determination of M. margarita in four different areas showed that kaempferol was the main component of kaempferol, followed by quercitrin. The contents of five components of Mangosteen in different areas did not change much. The content of rutin, quercitrin, kaempferol-3-O-α-L-rhamnoside, quercetin and kaempferol were 0.109 ~ 0.176, 0.584 ~ 0.686, 2.416 ~ 2.627, 0.088 ~ 0.131 and 0.018 ~ 0.031 mg · g -1, respectively. Conclusion: The method is simple, rapid and efficient, which can be used to evaluate the quality and control the quality of the national medicine.
