摘 要:利用交替三線(xiàn)性分解(ATLD)算法輔助高效液相色譜-光二極管陣列檢測器(HPLC-DAD),用于快速、綠色定量檢測枳實(shí)中六種黃酮類(lèi)化合物。該方法得益于二階校正方法獨特的“二階優(yōu)勢”,部分“物理或化學(xué)分離”可以用“數學(xué)分離”替代,因此樣品的預處理步驟得到了簡(jiǎn)化,在存在重疊峰和未知干擾情況下,仍實(shí)現了對中藥枳實(shí)中六種黃酮類(lèi)化合物的同時(shí)、綠色、精準定量檢測,并且單樣本檢測時(shí)間小于7 min,具有良好的線(xiàn)性和令人滿(mǎn)意的回收率。結果表明,本方法可以作為一種高效的策略用于同時(shí)定量檢測中藥中的多種化學(xué)成分,為中藥品質(zhì)把控提供一定指導。 |

Abstract:In this work, a fast analysis strategy that the high-performance liquid chromatography-diode array detection (HPLC-DAD) coupled with the alternating trilinear decomposition (ATLD) algorithm was proposed for simultaneous quantitation of 6 flavonoids in fructusaurantiiimmaturus (AFI). Instead of "chemical separation", "mathematical separation" was chose to simplifysample pretreatment, which benefited from the "second-order advantages", making the accurate, green quantitation of 6 flavonoids in AFI within 7 min with satisfactory results. Experimental results indicated that the proposed method was a high-efficiencystrategy for simultaneous determination of multi-components in complex traditional Chinese medicines. |
