摘要(Abstract):

[Objectives]To study the differences in the content of aqueous extract and total flavonoids in different parts of Sichuan Ophiopogon japonicus 1,and provide a scientific basis for the comprehensive utilization of O. japonicus resources. [Methods] According to Volume I of 2015 Chinese Pharmacopoeia,and with reference to literature methods,taking water as extraction solvent,hot dip method was used to determine the content of aqueous extract; taking ethanol as extraction solvent,the content of total flavonoids was determined using hot dip method,Ultraviolet-Visible Spectrophotometry. [Results]The content of aqueous extract and total flavonoids in the root tubers of Sichuan O. japonicus1 was higher than that of traditional O. japonicas; the content of aqueous extract in the root tubers of Sichuan O. japonicus 1 was higher than that in the leaves of Sichuan O. japonicus 1; the content of total flavonoids in leaves of Sichuan O. japonicus 1 was higher than that in the root tubers; the content of aqueous extract and total flavonoids in Sichuan O. japonicus 1 in the second year was higher than that in the first year.[Conclusions]The quality of new cultivar of Sichuan O. japonicas 1 was significantly higher than the traditional O. japonicus. Nowadays,the main part of drug use in O. japonicas is root,but as to the content of total flavonoids,fibrous roots and leaves are more dominant,it is feasible to develop and utilize the resources of flavonoids in the fibrous roots and leaves. The content of aqueous extract and total flavonoids from the second year O. japonicus was higher than that in the first year O. japonicus,but its increased amount did not meet the requirements of economic benefits.
