Abstract:

On the basis  of biosynthsis, distribution of diterpenoid  alkaloids  as
well as morphological evolution of Chinese species L. (Ranunculaceae), chemotaxonomy
of the genus Aconitum is discussed:
     1,  Subgen. Lycoctonum, containing lycoctonine-type alkaloids and Subgen. Aconi-
tum containing aconitine-type alkaloids, were probably differetiated at the early stage
of evolution of the genus Aconitum and evolved respectively in their own ways.
     2,  In Subgen. Aconitum: (1) Ser. Bullatifolia, containing mainly atisine-, veat-
chine-type alkaloids, and amino, alcohol and ester base of aconitine-type, and distribu-
ted in Hengduan Mountain and Jingsha River valley, where is the centre of modern
differentiation of species of Aconitum, is probably a series from which Chinese species
of the genus Aconitum were derived; (2) Ser.  Inflata,  containing mainly aconitine,
mesaconitine and bypaconitine, is an advanced group; (3) Ser. Grsndituberosa, conta-
ining mainly aconitine and songorine, is related to Ser.  Bulatifolia; (4) Ser. stylosa
and Ser. volubilia, containing mainly yunaconitine and other anisyl ester alkaloids form
another advanced branch.
     3,  Ser. Tangutica and A. naviculare of Ser. Rotaundifolia, containing atisine and
lactone-type alkaloids may be a specialized group in high mountains and have occurred
at early stage of evolution of the genus Aconitum.
     4,  Subgen. Gymnaconitum, containing atisine-type alkaloids and amino alcohol of
aconitine type, may als be a specialized group in high mountains.
     5,  A. franchetii Finet. et Gagnep. mainly containing ester bases of aconitine-type
and closed to A. chasmanthum Stapf, is best placed into Ser. Ambigua.
