A new Erythrina alkaloid from Erythrina herbacea

Journal of Natural Medicines, 2008
A new Erythrina alkaloid, 10-hydroxy-11-oxoerysotrine (1), has been isolated from the flowers of Erythrina herbacea together with five known compounds: erytharbine (2), 10,11-dioxoerysotrine (3), erythrartine (4), erysotramidine (5) and erysotrine-N-oxide (6). The structure of the new compound was elucidated on the basis of its spectral data, including

Biosynthesis of Erythrina alkaloids in Erythrina crista-galli

Phytochemistry, 1999
A precursor application system was developed to allow the study of Erythrina alkaloid formation in Erythrina crista-galli. Fruit wall tissue of this species was recognized as the major site of alkaloid biosynthesis. The application of radioactively and 13C-labelled potential precursors showed that the hitherto assumed precursor (S)-norprotosinomenine ...

Erythrina alkaloids from leaves of Erythrina arborescens

Tetrahedron, 2019
Continued interest in Erythrina alkaloids resulted in the isolation of 38 alkaloids including 7 undescribed ones from the leaves of Erythrina arborescens Roxburgh. Among the new compounds, erythrivarines H-I were two dimeric alkaloids, while others were Erythrina alkaloid glucosides.

[Erythrina alkaloids from stems of Erythrina corallodendron].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2021
This study aims to investigate Erythrina alkaloids from the stems of Erythrina corallodendron. Eighteen Erythrina alkaloids were isolated from the 95% ethanol extract of the stems of E. corallodendron by silica gel,octadecyl silica( ODS),Sephadex LH-20 column chromatography and preparative HPLC.

Erythrina sp.III: Chemical Constituents of Erythrina Suberosa Roxb.Seeds

Journal of Pharmaceutical Sciences, 1970
Abstract A phytochemical investigation of Erythrina suberosa seeds has resulted in the isolation of erythraline, erysodine, erysotrine, and hypaphorine.This is the first time that erysotrine has been found to occur naturally, although it is well known as a conversion product of other eryso-alkaloids.The alkaloidal constituents were found to vary in

Three new erythrina alkaloids from the roots of Erythrina corallodendron

Journal of Asian Natural Products Research, 2021
Three new erythrina alkaloids, eryalkals A (1), B (2), and C (3), were isolated from the roots of Erythrina corallodendron L. Their structures, including their absolute configurations, were elucidated based on analyses of HR-ESI-MS, 1D/2D NMR and single-crystal X-ray diffraction techniques.
