TABLE 1 determination of the Total Saponin content in Polygonatum sibiricum Red
Total saponin content
Example 1 Polygonatum sibiricum planted by the method 4.543mg/g
Example 2 Polygonatum sibiricum planted by the method 2.652mg/g
Example 3 Polygonatum sibiricum planted by the method 2.136mg/g
Comparative example 1 sealwort planted by the method 1.328mg/g
The data in table 1 show that the total saponin content of the polygonatum sibiricum prepared in examples 1-3 is far higher than that of the polygonatum sibiricum planted in the method of comparative example 1.
