Discrimination of cinnamon bark and cinnamon twig samples sourced from various countries using HPLC-based fingerprint analysis

Influence of herbal combinations on the extraction efficiencies of chemical compounds from Cinnamomum cassia , Paeonia lactiflora , and Glycyrrhiza uralensis , the herbal components of Gyeji-tang, evaluated by HPLC method

“…Gallic acid (1), isoliquiritin (7), ononin (8), and glycyrrhizin (16) were purchased from ChemFace (Wuhan, Hubei, China). Albiflorin (2), benzoic acid (6), coumarin (9), and cinnamyl alcohol (11) were from Wako Pure Chemical Industries Ltd. (Osaka, Japan).…”

“…These analytical techniques have also been employed to identify marker compounds in CC, PL, and GU, that is, cinnamic acid, cinnamaldehyde, coumarin, cinnamyl alcohol, and 2-methoxy cinnamaldehyde in CC [7][8][9]; gallic acid, albiflorin, paeoniflorin, 1,2,3,4,6-pentagalloylglucose, benzoic acid, and benzoylpaeoniflorin in PL [10,11]; and liquiritin, liquiritigenin, glycyrrhizic acid, ononin, and isoliquiritin in GU [12,13]. Thus, we considered these compounds could be used as markers of CC, PL, or GU, because they represent the chemical make-up of those herbs, and could be used for quality control or quality assessment.…”

Study of Chemical Fingerprint for Yuanhu Zhitong Tablet by Uplc/Q-Tof-MS

“…[3][4][5] Consequently, in recent years the fingerprint technique has been the focus of attention and has also been accepted as a feasible technique for the quality control of TCM. [6][7][8][9][10] The recently developed ultra-performance liquid chromatography coupled with quadrupole time of flight tandem mass spectrometry (UPLC=Q-TOF-MS) technique has shorter analysis time and higher sensitivity. [11,12] Importantly, this technique could identify components based on MS=MS mode, which greatly facilitate the research of fingerprint.…”

Manufacturer identification and storage time determination of “Dong’e Ejiao” using near infrared spectroscopy and chemometrics

“…The analysis is often based on chromatographic separation techniques such as gas chromatography (GC), high-performance liquid chromatography (HPLC), and capillary electrophoresis (CE), combined with ultraviolet (UV), diode array detector (DAD), evaporative light scattering detector (ELSD), or mass spectrometry (MS) (Xie et al, 2006;Liu et al, 2007;Alaerts et al, 2010;Ding et al, 2011). Such fingerprints can reflect the information of a few compounds with specific chromatographic properties and characteristic detection signals, but are unsuitable for holistic chemical composition.…”
