Abstract:
The plant chemotaxonomical marker of Fritillaria L. is discussed in this
paper according to the information on chemical components. Plenty of evidence
shows that 5α-cevanine isosteroidal alkaloids are the characteristic constituents of
this genus. In the light of the biogensis of this kind of alkaloids, the C-13 and
C- 17 of the molecular structures may be rational positions uniting a nitrogenous
group in their biosyntheses which make two kinds of 5α-cevanine isosteroidal
alkaloids, the dihydrogen of C- 13 and C- 17 being at the state of
trans-configuration (e. g. verticine, verticinone) and at the state of cis-
configuration (e.g. delavine, chuanbeinone and songbeinine). Meanwhile, this
paper reports the existence and content of some 5α-cevanine isosteroidal alkaloids
in main Chinese fritillarias. This result reveals that there may be a relationship
between the formation of characteristic constituents on one hand and other
morphological characters and distribution of the plants concerned on the other,
which encourages further investigation.
