Difference of effective component content of traditional Chinese medicine harvested in different years based on the theory of'materials prepared by a particular year'in Huangdi Neijing
According to the theory of'correspondence between heaven and man'and the theory of five movements and six qi,Huangdi Neijing constructs the theory of'materials prepared by a particular year'to ensure the quality of drugs,and explains the mechanism of collecting drugs corresponding to climate change according to the characteristics of climate change in different years,which lays a theoretical foundation for the so-called'genuine medicinal materials'in future generations.In recent years,many Chinese pharmaceutical professionals have used different detection methods such as high performance liquid chromatography,bromocresol green colorimetry,phenol sulfuric acid method and response surface method,and so on to detect the content of effective components of different traditional Chinese medicines such as Acanthopanacis Senticosi Radix Et Rhizoma Seu Caulis,Sophorae Flavescentis Radix,Polygonati Rhizoma,Ginseng Radix Et Rhizoma,Curcumae Radix,Alpiniae Officinarum Rhizoma,Gastrodiae Rhizoma collected in different years,which confirms the scientificity of the theory of'materials prepared by a particular year'of drugs according to the change of luck in each year.At the same time,it provides important reference value for the most suitable harvest year of traditional Chinese medicine,its quality evaluation and control,and the effective development and utilization of traditional Chinese medicine resources.
