Method Development and Validation for Simultaneous Analysis of Eleven Components for Quality Control of Geumgwesingihwan Using HPLC–DAD and UPLC–MS/MS

Abstract

Geumgwesingihwan (GGSGH) is an oriental herbal formula made by adding Achyranthes bidentate Blume and Plantago asiatica L. to Yukmijiwhanghwan. It has been used for the treatment of edema since ancient times. The purpose of this study is to develop and validate a method for simultaneous quantification of 11 components: gallic acid (1), 5-(hydroxymethyl)furfural (2), geniposidic acid (3), morroniside (4), loganin (5), paeoniflorin (6), acteoside (7), cornuside (8), benzoic acid (9), benzoylpaeoniflorin (10), and paeonol (11), using high-performance liquid chromatography with a diode array detector (HPLC–DAD) and ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS). Compounds 1–11 were separated on a Capcell Pak UG 80 C18 column (250 mm × 4.6 mm, 5 μm) using a mobile phase of a distilled water–acetonitrile system, both containing 0.1% formic acid. In UPLC–MS/MS, compounds 1–11 were separated on an Acquity UPLC BEH C18 column (100 mm × 2.1 mm, 1.7 µm) using a mobile phase of a distilled water–acetonitrile system containing 1.0% acetic acid. Using these methods, samples of GGSGH were determined to contain 0.13–2.87 mg/g (HPLC–DAD) and not detected–4.60 mg/g (UPLC–MS/MS) of compounds 1–11. The developed HPLC–DAD assays for simultaneous determination of all analytes were validated with respect to linearity, limits of detection and quantification, recovery, and precision. The established HPLC assay will be used to obtain basic data for quality evaluation of GGSGH and related oriental herbal formulas.
