ZHOU Ri-bao GAO Jing TONG Qiao-zhen HE You-shun QU Wei-hong LUO Mu-he(Traditional Chinese Medicine College of Hunan, Changsha,410004,China)  
Objective To compare quality of Herba Houttuyniae of different strains. Method Periodically sample in order to quantitatively determine the contents of methyl-n-nonyl-ketone,moisture, ashes and extracts.Determine output of individual zones upon harvest and give a variance analysis to data.Result Contents of methyl-n-nonyl-ketone and its total amount of unit zone significantly vary with strains. Agricultural nature and output also vary. Conclusion Strain with green stem is more robust and has a larger output. However, strain with red stem has a higher content of methyl-n-nonyl-ketone and a higher total amount of unit zone than strain with green stem. Therefore, the red-stem strain is favored and recommendable.
