Diterpenoid Alkaloids from Delphinium ajacis
Five new diterpenoid alkaloids, ajacisines A–E (1–5), were isolated from Delphinium ajacis, along with seven known alkaloids (6–12). On the basis of their spectral data (IR, UV, HR‐ESI‐MS, 1D and 2D NMR) and chemical properties, the structures of compounds 1–12 were identified. All isolated compounds were evaluated for their in vitro antiviral activities against respiratory syncytial virus, and...
متن کاملNew diterpenoid alkaloids from the roots of Delphinium tiantaishanense.
Four new diterpenoid alkaloids: tiantaishansine (1), tiantaishannine (2), tiantaishanmine (3), and tiantaishandine (4) have been isolated from the roots of Delphinium tiantaishan. Their structures were elucidated by chemical evidence and spectral analyses, including ESI-MS, HR-EI-MS, 1D- and 2D-NMR.
متن کاملPharmacologically Active C-19 Diterpenoid Alkaloids from the Aerial parts of Aconitum laeve Royle
Two new lycoctonine type C19-diterpenoid alkaloids, swatinine-A (1), and swatinine-B (2), along with four known C19-diterpenoid alkaloids, foresticine (3), neoline (4), delvestine (5), and chasmanine (6), were isolated from the aerial parts of the Aconitum laeve Royle. The structures of compounds 1 and 2 were deduced on the basis of spectroscopic techniques (EI-MS, HREI-MS, H NMR, C NMR, HMQC, ...
متن کاملNorditerpenoid alkaloids from Delphinium kohatense Munz
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)...
متن کاملNorditerpenoid alkaloids from Delphinium flexuosum Bieb.
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.
