lycoctonine/consolida

A new norditerpene alkaloid was isolated, 18-demethylpubescenine (1), in addition to four known compounds, 14-demethyltuguaconitine (2), takaosamine (3), gigactonine (4), and delcosine (5), from fresh, whole plants of Consolida orientalis. The structure of 1 was established by spectroscopic methods,

The structures of three new norditerpenoid alkaloids named dehydrodeltatsine (1), 14-O-acetyltakaosamine (2), 18-demethoxypubescenine (3) isolated from the aerial parts of Consolida orientalis (GAY) SCHROD., were elucidated by 1D and 2D NMR spectroscopy and HR-EIMS. Twelve known norditerpenoid

Larkspurs (Delphinium spp.) are toxic plants that contain numerous diterpenoid alkaloids which occur as one of two structural types: (1) lycotonine, and (2) 7,8-methylenedioxylycoctonine (MDL-type). Among the lycoctonine type alkaloids are three N-(methylsuccinimido) anthranoyllycoctonine

Four new diterpenoid alkaloids, olivimine (1), olividine (2), 8-O-methylcolumbianine (3), and 7alpha-hydroxycossonidine (4), were isolated from the aerial parts of Consolida oliveriana. Compounds 1 and 2, 3, and 4 belong to the lycoctonine-azomethine, aconitine, and hetisine types, respectively, and

Fourteen norditerpenoid alkaloids present in larkspur (Delphinium) species associated with cattle poisoning on grazing land in the western United States have been toxicologically assessed in a mouse bioassay. Toxicity data for these alkaloids have established the tertiary nitrogen atom and

Seven diterpenoid alkaloids : delcosine(1), delsoline(2), gigactonine(3), lycoctonine(4), takaosamine(5), atisine(6) and hetisinone(7) have been isolated from the aerial parts of Consolida regalis subsp. paniculata var. paniculata. The presence of compounds 1,2,5,6 and 7 in this plant has not been

The purpose of this study was to determine whether larkspur toxins conjugated to protein carriers would promote active immunity in mice. Mice were injected with several larkspur toxin-protein conjugates or adjuvant alone to determine whether the resulting immunological response altered animal
