3、tion Platycosides, the primary constituents of Platycodi Radix, are known to have numerous and varied biological activities, exerting anti-inflammation, anti-allergy, anti-tumour, anti-obesity and anti-hyperlipidemia effects. However, effective methods for isolating and purifying platycosides from P
4、latycodi Radix are not currently available. Objective To develop an efficient method for the preparative separation of six platycosides from Platycodi Radix by high speed counter-current chromatography (HSCCC) coupled with an evaporative light scattering detection (ELSD) system. Methodology Preparat
5、ive separation was performed by water extraction using reversed-phase C18 column chromatography on an HSCCC-ELSD system. A two-phase solvent system comprised hexanen-butanolwater (1:40:20, v/v) and (1:10:5, v/v) was employed. Two other key parameters, revolution speed of the separation column and fl
6、ow-rate of the mobile phase, were also investigated for optimum HSCCC performance. Each peak fraction obtained from separation of the platycosides was collected according to the ELSD elution profile and determined by HPLC. Results Using the described method, six platycosides, all with purities of ov

16、ricum perforatum L., a typical traditional Chinese medicine, is used all over the world for the treatment of depression. Additionally, it has been reported that the extracts of H. perforatum may have an inhibitory effect, on human bladder cancer cells , and act as an antioxidant and anticonvulsant.
17、The extracts of H. perforatum contain many constituents with documented biological activity such as quinic acids, phloroglucinols and a broad range of flavonoids . Exposure of the extracts of H. perforatum to light may lead to the degradation of phloroglucinols, which are extremely sensitive to oxid

Then the aqueous phase containing 2% NH4OH (eluter base) was pumped into the inlet of the column at a flow-rate of 3.0 mL/min in the head to tail elution mode, while the apparatus was rotated at 750 rpm. After peaks I and II were eluted out of the column, the mobile phase was changed to the aqueous phase containing 0.2% NH4OH until peak III were eluted out. Following this, the mobile phase was changed to the aqueous phase containing 0.01% TFA to elute peaks VI and
