Alkaloids constitute the largest class of plant secondary compounds, occurring in 20 to 30% of perennial herbaceous species in North America. Alkaloid-containing plants are of interest, first because alkaloids often have pronounced physiological reactions when ingested by livestock, and second because alkaloids have distinctive taste characteristics. Thus, alkaloids may kill, injure, or reduce ...

By killing cattle and otherwise complicating management, the many species of larkspur (Delphinium spp.) present a serious, intractable, and complex challenge to livestock grazing management in the western United States. Among the many obstacles to improving our understanding of cattle-larkspur dynamics has been the difficulty of testing different grazing management strategies in the field, as t...

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...
