The ruthenium can be further divided into RA, RC, RD, RE and the like, wherein RA is a colorless crystal. The sweetness is 450 times that of sucrose, and the sweetness is pure, similar to sucrose.

RC accounts for 10%-15%, and RD and RE account for a small proportion.
The cockroaches can be divided into two types, DA and DB. Among them, DB and RC are the same substance, DA is also relatively small in dry leaves, and the sweetness is about 150 times that of sucrose.
