Research Status and Analysis of Main Active Ingredients in Kuandonghua(Farfarae Flos)from Different Habitats
Kuandonghua(Farfarae Flos)is the dried flower buds of the Kuandonghua(Tussilago farfara L.),and is one of the most commonly-used Chinese herbal medicines in our country.Kuandonghua(Farfarae Flos)is rich in chemical compo-nents,and has high medicinal value and a good clinical efficacy.However,due to the influence of factors such as environment and cultivation conditions,there are differences in the growth state,physicochemical properties,medicinal properties and secondary metabolite accumulation of Kuandonghua(Farfarae Flos)from different origins.In particular,the main chemical components of Kuandonghua(Farfarae Flos)in different regions are uneven,leading to an uneven quality of medicinal materials.Based on this,many years of research results of our country producing Kuandonghua(Farfarae Flos)were provided in this paper,Kuandonghua(Farfarae Flos)is collated in research literatures,meanwhile the main chemical composition of sesquiterpenoids,phenolic acids,flavonoids and alkaloids was summarized by using data collection and transverse comparison.The research status of components of Kuandonghua(Farfarae Flos)from different producing areas was summarized in this paper while peering into its component differences from the perspective of its iconic components,which provided data support for the research on common and individual characteristics of Kuandonghua(Farfarae Flos)from different producing areas.
