Abstract
A research was conducted to determine the active ingredient in Angelica sinensis using TLC and HPLC analysis. Angelica was extracted by using three difference slovents; which is water, methanol and methanol - fomic acid (95:5). From the analysis it was found that methanol and methanol - fomic acid (95:5) are best for exracting the phenolic compounds. Results showed that about 11.5% of ferulic acid was extracted by water, 17.5% of ferulic acid was extracted by methanol and 7.81% of ferulic acid was extracted by methanol formic acid (95:5). The thin layer chromatorgraphy of the three extracts showed the presence of eight spots out of which one spot has a Rf value close to ferulic acid The retention time found from the HP LC analysis of the sample also confirmed the presence of this compound in Angelica sinensis.
