Diterpenoid Alkaloids from Delphinium liangshanense
CHEMISTRY & BIODIVERSITY(2024)
Abstract
Two new C-19-diterpenoid alkaloids of the lycoctonine-type (liangshanine A and liangshanine B) and nineteen known compounds (3-21) were isolated from the whole plant of Delphinium liangshanense W. T. Wang, and all the compounds were identified by different spectroscopic analyses, such as IR, HR-ESI-MS and NMR. All the compounds were isolated from this plant for the first time and tested for the anti-proliferation effects on MH7 A and SF9 cells to figure their anti-rheumatoid arthritis and anti-insect activity, but none of them showed remarkable activity.
