Abstract: To compare total sugar and flavone contents in Radix Ranunculi Ternati from different places.Anthronevitriol colorimetry was used to determine total sugar content in Radix Ranunculi ternati using glucose as observation index.Spectrophotometry was used to determine flavone contents using rutin as observation index and NaNO₂-Al(NO₃)₃-NaOH as coloration system.The contents of total sugar in Radix Ranunculi Ternati derived from Xinyang Henan,Anhui,Zhejiang,Shanxi and Shandong were 18.93%,15.46%,11.78%,9.21%,9.46%,the contents of flavone were 0.95%,0.32%,0.47%,0.19%,0.28%,respectively.Total sugar and flavone contents in Radix Ranunculi ternati from different places are significantly different,and the highest is the one from Xinyang Henan.

Key words: Radix Ranunculi Ternati, total sugar, flavone, spectrophotometry, content determination
