1, the external morphology is different: Notoginseng Notoginseng is the Notoginseng that retains the rhizome. The rhizome of panax notoginseng is easy to fall off in the process of sun-drying. Therefore, if it is necessary to obtain cut Notoginseng, it should be tied with rubber bands in the process of drying. Notoginseng without scissors has only one cone-like main root. The drying process of Notoginseng Radix without cutting is relatively simple.
2. The content of chemical active ingredients is different: triterpenoid saponins are the effective ingredients in Panax notoginseng. Cutting plays a role in transporting nutrition during the growth of Panax notoginseng. Therefore, the content of triterpenoid saponins in the cut of Panax notoginseng is higher than that in other positions. Therefore, the triterpenoid saponin content of Notoginseng Radix is higher than that of Notoginseng Radix without Notoginseng Radix.
