Combined Approach To The Choice Of Chromatographic Methods For Routine Determination Of Hederacoside C In Ivy Leaf Extracts, Capsules, And Syrup

Developed methods for routine analysis of medicines should be considered in terms of analytical efficiency, economic cost, as well as their environmental impact. Different chromatographic methods for the routine quantitative analysis of hederacoside C in ivy leaf extract and its original dosage forms (capsules and syrup) are developed. The performance of HPLC and UPLC methods should be done using ACE C18 (150 mm x 4.6 mm, 5.0 mu m) and ACQUITY UPLC BEH C18 (50 mm x 2.1 mm, 1.7 mu m) columns, respectively, and both of them require a mixture of water and acetonitrile in the ratio 71/29 as a mobile phase. The HPTLC procedure is carried out using the stationary phase pre-coated silica gel 60 F-254 glass sheets and a mixture of anhydrous formic acid/acetone/methanol/ethyl acetate (4:20:20:30 v/v). The most suitable conditions of preparation for each sample are established, for instance, the solid-phase extraction (SPE) for the analysis of syrup is applied. Analytical methods are compered by analytical accuracy, calculation of expenses, and assessment of their influence on ecology. All methods are recognized as accurate, precise, and reliable. However, the assessment of the environmental impact shows that HPTLC is the less green method. On the another hand, it is found to be the cheapest, the costs of performing HPTLC are 2.3 and 1.6 times lower than for HPLC and UPLC, respectively.
