The title compound, C(26)H(39)NO(7), which was isolated from Delphinium anthriscifolium var. majus, has a lycoctonine carbon skeleton containing four six-membered rings (A, B, D and E) and three five-membered rings (C, F and G). Rings A, B and E adopt chair conformation, while ring D adopts a boat conformation. Rings C and F adopt envelope conformations.

Delphiniflexine, a new norditerpenoid alkaloid, together with the three known norditerpenoid alkaloids methyllycaconitine, ajadine, and acoseptrigenine were isolated from the aerial parts of Delphinium flexuosum. The structure of delphiniflexine was established on the basis of 1H, 13C, DEPT, homonuclear 1H COSY, NOESY, HSQC, and HMBC NMR studies.

Delphinium caucasicum C.A. Mey. is illustrated from plants cultivated at the Royal Botanic Gardens, Kew. Its history, nomenclature and ecology are described instructions for its successful cultivation given.

Molecular sequence data show that the three species oDelphinium subg. Staphisagria (J. Hill) Peterm. form the sister clade to Aconitum L., Aconitella SpachConsolida (DC.) S.F. Gray, and all remaining species of Delphinium L. To account for this finding we resurrect Staphisagria J. Hill (1756). Names in Staphisagria are available for two of the species. We here make the required new combination ...

The taxonomic status of Thamnurgus rossicus was evaluated with respect to the morphologically similar T. petzi using genetic markers. Nucleotide data from the mitochondrial COI gene revealed 2.4% variation between the European Alps and Russian steppe populations. The two nuclear DNA markers CAD and EF1á were identical across populations. In view of their similar morphology, genetic composition,...

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...
