OBJECTIVES: A high-performance liquid chromatography (HPLC) method was developed to examine five isoflavonoids present in Chinese herbal medicinal products containing Radix Puerariae. METHODS: Five isoflavonids, puerarin, daidzin, genistin, daidzein and genistein, were measured by HPLC. The HPLC system was equipped with an ODS-AM-303 column (250 mm x 4.6 mm i.d., 5 microm) and established gradient system comprising glacial acetic acid/water and glacial acetic acid/acetonitrile...

OBJECTIVE: To prepare chitosan coated puerarin liposomes and investigate their physicochemical properties. METHODS: Puerarin liposomes were prepared by reverse phase evaporation technique and then coated with chitosan. Using encapsulation efficiency as index of examination and designing an orthogonal experiment, the optimal formulation of liposomes was determined. The physicochemical properties of uncoatd and chitosan coated puerarin liposomes were investigated, respectively...
