THE TITLE COMPOUND (SYSTEMATIC NAME 5,6β-dihy-droxy-1α,14α,16β-trimeth-oxy-4-methyl-7β,8-methyl-enedi-oxy-20-ethyl-aconitan-6-yl acetate acetone monosolvate), C(27)H(41)NO(8)·C(3)H(6)O, was isolated from Delphinium bonvalotii Franch, and is a typical C(19)-diterpenoid alkaloid. The mol-ecule has a lycoctonine carbon skeleton with four six-membered rings and three five-membered rings. Three six-...

how the seeds of delphinium staphisagria promote hair growth in humans is yet to be discovered. this lack of information leads us to the investigation of hair promoting effects of seeds of delphinium staphisagria in vitro. extract prepared from the seed of delphinium staphisagria (esds) - traditionally used for hair loss treatment - was selected and tested for the cytotoxic and angiogenic poten...

The outcome of species interactions is often difficult to predict, depending on the organisms involved and the ecological context. Nectar robbers remove nectar from flowers, often without providing pollination service, and their effects on plant reproduction vary in strength and direction. In two case studies and a meta-analysis, we tested the importance of pollen limitation and plant mating sy...

There are numerous species of larkspur (Delphinium spp.) in North America. Larkspurs are a major cause of cattle losses on western ranges in the USA, especially on foothill and mountain rangelands. The toxicity of larkspur species is due to various norditerpenoid alkaloids. In this article, we review the current knowledge regarding larkspur ecology and distribution, analytical technologies to s...

A new aconitine-type norditerpenoid alkaloid, kohatenine (1) [10β-hydroxy-1α,8β,16β-trimethoxy6α,14α-diacetyl-N-ethyl aconitane], along with four known alkaloids, condelphine (2), talatisamine (3), peregrine (4), and 14-O-acetyltalatisamine (5), was isolated from the aerial parts of Delphinium kohatense Munz. The structure of the new compound was deduced on the basis of combined MS (EI and FAB)...
