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 کاملAnticancer Activities of C18-, C19-, C20-, and Bis-Diterpenoid Alkaloids Derived from Genus Aconitum.
Cancer is one of the most common lethal diseases, and natural products have been extensively studied as anticancer agents considering their availability, low toxicity, and economic affordability. Plants belonging to the genus Aconitum have been widely used medically in many Asian countries since ancient times. These plants have been proven effective for treating several types of cancer, such as...

Three new flavanols, 5-p-hydroxybenzoxy-7-hydroxyl-8-ethoxycarbonyl-( - )-afzelechin (1), 5-p-hydroxybenzoxy-7-(2, 3, 5-trihydroxybenzoxy)-8-ethoxycarbonyl-( - )-afzelechin (2), and 5-p-hydroxybenzoxy-7-(2, 3, 5-trihydroxybenzoxy)-8-methoxycarbonyl-( - )-afzelechin (3), were isolated from Daphne giraldii Nitsche and their structures were elucidated by spectroscopic methods, especially by 2D-NMR...
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)...
