[Analysis on yield and quality of different Houttuynia cordata].
OBJECTIVE
To study the yield of different Houttuynia cordata and the changing regularity of their main officinal components in different periods, and provide a basis for harvesting in good time and breeding new varieties.


METHODS
The main officinal composition and wet weight of overground parts per acreage of different accessions were determined periodically. The plot yields were tested when harvested and analyzed by analysis of variance.


RESULTS
The difference of the yields of different accessions was significant. The varying tendency of the content of main officinal component methyl nonyl ketone and its total content per acreage of different accessions were different.


CONCLUSIONS
The integrate characters of Qionglai and Wangyu wild accessions are relatively better, worthy to be widely applied in production.
