Abstract:

Reversed-phase high performance liquid chromatography was used to analyze water-soluble amino acids in the
normal Amorphophallus Konjac, Amorphophallus albus, Amorphophallus bulbifer, and the soft rot Amorphophallus Konjac,
to determine the relationship of the different soft-rot resistant Konjac varieties and the proportion and content of
the multiple water-soluble amino acids. The results showed that there are remarkable differences in the content and
proportion of water-soluble amino acids in different resistant varieties and the same variety of normal and diseased
leaves of Amorphophallus. In this study, the bank of fingerprint chromatogram was established and can be used to
analyze the related characteristic peaks and the resistance of Amorphophallus.

Key words: Konjac leaf blade, resistance , water-soluble amino
acids, reversed-phase high performance liquid chromatography (RP-HPLC)
