| Abstract: | The content of total polyphenol in eggplant root was determined by using improved Folin-Ciocalteu colorimetry.The results showed that in the range of 0.009 6-0.076 8 mg,the linear relationship of standard curve of reference substance was good.The average content of total polyphenol in 75% alcohol extract from eggplant root was 0.272% and its RSD was 0.98%.The average recovery of standard addition of this method and its RSD were 97.47% and 3.64% resp. |
