dihydrochelerythrine/macleaya

The antifungal activities of dihydrosanguinarine and dihydrochelerythrine, isolated from the leaves of Macleaya microcarpa, were evaluated on 12 plant pathogenic fungi; the two compounds exhibited the highest antifungal activity against Botrytis cinerea Pers. Among the 11 tested plant pathogenic

Ichthyophthirius multifiliis is a holotrichous protozoan that invades the gills and skin surfaces of fish and can cause morbidity and high mortality in most species of freshwater fish worldwide. The present study was undertaken to investigate the antiparasitic activity of crude extracts and pure

A specific and reliable HPLC-MS/MS method was developed and validated for simultaneously determination of sanguinarine, chelerythrine and their metabolites (dihydrosanguinarine and dihydrochelerythrine) in chicken tissue for the first time. This is important because these compounds are related to

Ongoing study on the chemical constituents of the roots of Macleaya microcarpa led to the isolation of eight compounds of derivatives of triterpenes and organic acids in addition to some previously identified benzophenanthridines. The eight compounds were identified by spectroscopic methods as well

BACKGROUND Some isoquinoline alkaloids from Macleaya cordata (Willd). R. Br. (Bo Luo Hui) exhibited antibacterial, antiparasitic, antitumor, and analgesic effects. The targets of these isoquinoline alkaloids are undefined. This study aims to investigate the compound-target interaction network and

OBJECTIVE To study the alkaloids of Macleaya cordata. METHODS The alkaloids were isolated and purified by various column chromatography as well as recrystallization. Their structures were identified by physico-chemical properties and spectral analysis. RESULTS Thirteen alkaloids were isolated and

To study the alkaloids from the fruit of Macleaya cordata. The alkaloids were isolated and purified by silica gel column chromatography and preparative high performance liquid chromatography,and the structures were elucidated based on the spectral data. Eight alkaloids were obtained from the

Macleaya cordata (plume poppy) is a source of bioactive compounds, mainly isoquinoline alkaloids which are used in phytopreparations with anti-inflammatory and antimicrobial activities. In this study, the alkaloids sanguinarine, chelerythrine, their dihydro derivatives, protopine and allocryptopine

A method for the analysis of alkaloids in Macleaya cordata (Willd.) R. Br. using high-performance liquid chromatography with diode array detection and electrospray ionization mass spectrometry (HPLC-DAD-ESI/MS) was developed. Using protopine (PRO), allocryptopine (ALL), sanguinarine (SA), and
