Diterpenoid Alkaloids of Aconitum sungpanase

Trans-2,2′,4,4′-tetramethyl-6,6′-dinitroazobenzene from Aconitum sungpanense

Trans-2,2',4,4'-tetramethyl-6,6'-dinitroazobenzene from the leaves of Aconitum sungpanense was reported as a new compound. The structure was determined by spectroscopic methods and X-ray diffraction analysis.

New norditerpenoid alkaloids from Aconitum hemsleyanum var. leueanthus

Four new norditerpenoid alkaloids, leueantines A (1), B (2), C (3), and D (4), were isolated from the roots of Aconitum hemsleyanum var. leueanthus. The structures of 1-4 were established by spectroscopic evidence.

New norditerpenoid alkaloids from Aconitum hemsley anum var. pengzhouense

Two new norditerpenoid alkaloids, 13-deoxyludaconitine (1) and 8-deacetylsungpaconitine (3), were isolated from the roots of Aconitum hemsleyanum Pritz var. pengzhouense and their structures were elucidated by spectral data.
