Nowadays,high performance liquid chromatography（HPLC）is the most widely used analytical method.In this review,we summarize the principle of the choice of HPLC column and mobile phase,discuss and compare the features of various detections such as UV,fluorescence detection,electrochemical detection,chemilummescence detection,UV-MS etc.Recent developments in HPLC including ultra-LC and miniaturization of LC（micro-LC,capillary-LC,and nano-LC）,are also discussed.展开更多

The structure of the new compound was elucidated by sepctral techniques, viz. 1D, 2D NMR spectra and HR-ESI-MS. Compared with berberine hydrochloride, typicalvone A showed moderate anti-bacterial activities, especially against the Gram-negative Paeudomonas aeruginosa ATCC-9027 and Escherichia coli ATCC-25922, with MBC values of 1000 and 500 μg/mL, respectively. In addition, it exhibited weak inhibitory activities against the tumour cells.展开更多
