OBJECTIVE To explore the once sampling quantitation of Houttuynia cordata through its DNA polymorphic bands that carried information entropy, from other form that the expression of traditional Chinese medicine polymorphism, genetic polymorphism, of traditional Chinese medicine. METHOD The technique of inter simple sequence repeat (ISSR) was applied to(More)
OBJECTIVE To establish and experimental verification the mathematical model of the balance groups that is the steady-state of traditional Chinese medicine in extraction. METHOD Using the entropy and genetic principles of statistics, and taking the coefficient of variation of GC fingerprint which is the naphtha of the Houttuynia cordata between strains in(More)
