Liang Nan-xi, Yu Hong, Zhang Li‐juan

Abstract

A TLC method for determination of scutellarin in individual Erigeron breviscapus was established,for choosing the plant contained high scutellarin.The mobile phase was ethyl acetate-formic acid-water(5∶1∶1) and the detecting wavelength was 337?nm.The linear relationship ranged from 0.204?μg to 1.632?μg with a correlation coefficient 0.999?5,the average recovery was 96.7%,RSD was 3.90%.This method is simple,sensitive and accurate.It can be used in screening a good individual among a great deal of plants.
