From the figure 3, the content of RA and STV indicate the two components percentage in total
glycosides, respectively. It can be seen from the figure 3, the total glycosides of the leaves is 14.63% in
organic manure cultivation condition, while it is 13.38% in chemical fertilizer cultivation, so the total
glycosides organic manure cultivation is significantly higher than the chemical fertilizer cult ivation. The
STV and RA percentage of organic manure cultivation is 9.33% and 67.2%, respectively, while the STV
and RA percentage of other treatment is 66.8% and 9.65%. Organic manure can improve the total
glycosides of the leaves significantly, but there is no effect on the content of RA and STV.
