Abstract

I assessed the B(a)P content from the Ginseng extract, Red ginseng extract, and Ssangwha extract which have high viscosities. It wasn`t easy to extract oil from these samples, consequently measuring of B(a)P was difficult. In order to know the exact detecting contents, I injected standard material of B(a)P to the above extractions and pre-treated for measurement but it was also difficult to measure of contents exactly. To improve of detecting method, I removed mucinous materials using a 85% phosphoric acid solution or 10% citric acid solution and then processed continuously with 60℃ hot water. The analysis revealed that extracting the samples contained B(a)P determined the rate of each 70%, 55%, 67% could increase. As a result the detecting method of B(a)P contents could be improved.
