  abstractNote={<jats:title>Abstract</jats:title><jats:p>Three new diterpene alkaloids, tangutidines A–C (<jats:bold>1</jats:bold>–<jats:bold>3</jats:bold>), and four known alkaloids (<jats:bold>4</jats:bold>–<jats:bold>7</jats:bold>) were isolated from the whole plant of <jats:italic>Aconitum tanguticum</jats:italic>, from which amphoteric diterpene alkaloids (<jats:bold>1</jats:bold>–<jats:bold>3</jats:bold>) were obtained for the first time. The structures of <jats:bold>1</jats:bold>–<jats:bold>3</jats:bold> were elucidated by detailed interpretation of spectroscopic data, including MS and NMR data. All of them were evaluated for their cytotoxic activities.</jats:p>
