Due to its’ convenience, high-speed, sensitivity and fairly accuracy, it has been widely used in the areas of production of medicine, foodstuff, and environment etc.This thesis establishes several detection methods by Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC). It includes two sections—review and research report. In the review section, information about high performance liquid chromatography such as history, principles, HPLC equipment and the applications in the medicine analysis was summarized.

Simultaneous Determinations of Five Components in Beeswax Tablets by Reversed-Phase High-Performance Liquid ChromatographyA reversed high-performance liquid chromatographic method was employed to the determination of ferulic acid, benzoic acid, salicylic acid, cinnamic acid and quercetin in beeswax tablets. These five compounds were analyzed simultaneously with a shim-pack VP-ODS (150×4.6 mm, 5.0μm) and a guard column (10×4.6 mm, 5.0μm) by gradient elution using 0.2 % (v/v) phosphoric acid in water-methanol as the mobile phase.
