Corydalis bungeana Turcz. is an anti-inflammatory medicinal herb used widely in traditional Chinese medicine for upper respiratory tract infections. It is demonstrated that corynoline is its active anti-inflammatory component. The nuclear factor-erythroid-2-related factor 2 (Nrf2)/antioxidant
OBJECTIVE
To isolate and purify corynoline and acetylcorynoline from Corydalis bungeana and develop a reversed-phase HPLC method of determining the two components in C. bungeana.
METHODS
Alkaloids were isolated from the ethanolic extract with column gel chromatography, and identified on the basis of
Corynoline, the major isoquinoline alkaloid component derived from Corydalis bungeana Herba, has greatly impressed many scientists due to its various pharmacological effects. However, there is little information on its pharmacokinetics. In this study, a sensitive and rapid liquid chromatography with
Corynoline and acetycorynoline, the major active components derived from Corydalis bungeana Herba, showed multiple pharmacological activities. However, quantification of the two compounds in human urine has not been reported. A simple liquid chromatography with tandem mass spectrometry method for
Corynoline, a bioactive compound isolated from Corydalis bungeana Turcz., has been known to have anti-inflammatory activity. However, its effects on the inflammation of the cardiovascular system have not been reported yet. The aim of this study was to investigate the anti-inflammatory effects of
Corynoline (CRL), an isoquinoline alkaloid, is the major constituent derived from Corydalis bungeana Herba, which is a well-known Chinese herbal medicine widely used in many prescriptions. The purpose of this study was to comprehensively investigate the metabolism and bioactivation of CRL, and
BACKGROUND
Corydalis bungeana Turcz. (CB; family: Corydalis DC.) is an anti-inflammatory medicinal herb used widely in traditional Chinese medicine (TCM) for upper respiratory tract infection, etc., but its anti-inflammatory active molecules are unknown. This study was designed to screen for the
Corynoline, isolated from Corydalis bungeana Turcz, has been reported to possess anti-inflammatory and antibacterial activities. In this study, we aimed to explore the treatment effect of corynoline on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. In the present study, the
From the herbs of CORYDALIS BUNGEANA, 16 alkaloids were isolated; 3 of them were identical with acetylcorynoline ( 2), corynoline ( 5), protopine ( 9), which had been obtained before from this plant. A further 11 known alkaloids: dihydrosanguinarine ( 1), acetylisocorynoline ( 3), 11-epicorynoline (
Corynoline and acetycorynoline are active compounds of Corydalis bungeana Turcz. with various pharmacological effects such as sedation, anti-leptospira and liver injury protection effects. A specific, simple and sensitive UHPLC-ESI-MS/MS method was developed and validated for the pharmacokinetic
High-speed counter-current chromatography (HSCCC) was successfully applied for the preparative separation and purification of alkaloids from Corydalis bungeana Turcz. (Kudiding in Chinese) for the first time. After the measurement of partition coefficient of seven target alkaloids in the nine
Pharmacokinetic studies were conducted on rats for protopine, corynoline, 7'-(3',4'-dihydroxyphenyl)-N-[(4-methoxyphenyl)-ethyl]propenamide, acetylcorynoline, and 8-oxocorynoline, five main active components from Corydalis bungeana Turcz (C. bungeana Turcz). An ultra high performance liquid
Natural product corynoline is a unique isoquinoline alkaloid extracted from traditional Chinese medicine Corydalis bungeana Turcz, whereas its anticancer properties have not been investigated. In this study, we found that corynoline potently impairs the growth of melanoma cells, B16F10, and A375 in
UPLC-ESI-Orbitrap-MS/MS was used to analyze,identify and attribute the chemical constituents in Pudilan Antiphlogistic Oral Liquid. The analysis was performed on an Agilent Eclipse XDB-C18(4.6 mm × 150 mm,3.5 μm) with a gradient mobile phase of methanol-0.1% formic solution system at the flow rate
