Abstract
In order to provide data for clarifying the contents of sterols in ginseng, the determination of sterols was performed. The fresh ginseng was taken as the test samples. The methods for total sterols and monomeric sterol were established based on spectrophotometry-H3PO4-H2SO4-FeCl3 coloration and high performance liquid chromatography-evaporative light scattering detection (HPLC-ELSD), respectively. In the chapter, the content of total sterols is determined by spectrophotometry-H3PO4-H2SO4-FeCl3, and the monomeric sterol was detected by HPLC-ELSD. For the ginseng in same area, the sterol content of 5-year-old ginseng was the highest, and the sterol content of 6-year-old ginseng was the lowest. For the ginseng from various areas, the contents of sterol were different. In general, the distribution of sterol in 45 samples was different but lacks regularity.
