Dimeric Erythrina Alkaloids from the Flower of Erythrina variegata

Organic Letters, 2014
Unprecedented dimeric Erythrina alkaloids, spirocyclic (6/5/6/6) erythrivarine A (1) and spiro-fused (6/5/7/6) rings erythrivarine B (2), were isolated from the cultivated plant, E. variegata. The structures were determined on the basis of 1D and 2D NMR, FTIR, UV, and mass spectroscopic data and X-ray crystal diffraction. The biogenetic relationship of

Extractives from Erythrina eriotriocha

Journal of Natural Products, 1990
From the stem bark of Erythrina eriotriocha, a novel isoflavone, eriotriochin has been isolated and characterized, in addition to known compounds auriculatin, dihydroauriculatin, and 3'-O-methylorobol. The structure of compound 1 was determined by COSY, selective INEPT, 2D HMBC, NOESY, DEPT, and other spectroscopic techniques.

Anticonvulsant activity of hydroalcoholic extracts from Erythrina velutina and Erythrina mulungu

Journal of Ethnopharmacology, 2007
The anticonvulsant effects of hydroalcoholic extracts (HAEs) from the stem bark of Erythrina velutina and Erythrina mulungu on pentylenetetrazole (PTZ) and strychnine-induced seizure tests and the potentiation of pentobarbital-induced sleeping time in mice with the extracts were examined in this study.

Synthesis of the Erythrina Alkaloid Erysotramidine

The Journal of Organic Chemistry, 2014
A concise synthesis of erysotramidine (an alkaloid belonging to the erythrina family) was achieved starting with an inexpensive phenol and amine derivative. The synthesis is based on oxidative phenol dearomatizations mediated by a hypervalent iodine reagent and includes a novel route to a key indolinone moiety.
