Evaluation on Quality and Utilization Value of Bupleurum falcatum Linne

[Objectives]This study aimed to evaluate the quality of Bupleurum falcatum Linne interplanted with walnut in Ganluo and study the development and utilization value of other parts.[Methods]The contents of saikosaponins a and d were determined with RP-HPLC,and the contents of 7 kinds of harmful elements were determined by ICP-MS.The quality of B.falcatum Linne was compared with that of other Bupleurum species.[Results]The total saikosaponin content in Radix Bupleurum Falcatum(15.894 mg/g)was higher than that in Radix Bupleuri of other origins(8.748 mg/g).The total saikosaponin content in leaves of B.falcatum Linne(7.518 mg/g)is more than twice the limit promulgated by Chinese Pharmacopoeia.The contents of Al,Cr,Cu,As,Cd,Pb and Hg in B.falcatum Linne were all lower than the limits promulgated by the pharmacopoeia.In short,the quality of Radix Bupleurum Falcatum was better than that of Radix Bupleurum Marginatum(S3,S4)and Radix Bupleurum Sachalinense(S5).The leaves of B.falcatum Linne contained more saikosaponins and less harmful elements.[Conclusions]The method and technology of interplanting B.falcatum Linne with walnut in Ganluo are mature.The quality of the medicinal materials produced is superior,and the leaves are also rich in saikosaponins a and d,and can be used as the raw material for extracting saikosaponins a and d.This study provides a basis for further in-depth research on the cultivation of B.falcatum Linne in the domestic market.
