  1. Rh-01 ~ 10 represent free anthraquinones, combined anthraquinones, anthranones and their dimers, flavanols and their polymers, gallic acid and gallotannins, stilbene glycosides, naphthalene glycosides, butyrylbenzenes and their glycosides, chromones, and flavonoid (flavonol) glycosides in turn; The ordinal number after the values represents the order in each efficacy (the smaller the number, the higher the contributions of this category to the efficacy)
