RESUMEN
Objective:To study the quality standard for Fujie lotion. Methods:The qualitative identification of Sophora alopecu-roides L, Cnidium monnieri ( L. ) Cuss and borneol was detected by TLC. The quantitative determination of matrine was detected by HPLC. Results:The identification by TLC was highly specific, and the content determination method was accurate and repeatable. The linear range of matrine was 0. 013 0-1. 30 mg·ml-1, and the average recovery was 97. 1% with RSD of 1. 7%(n=6). Conclu-sion:The standard can effectively control the quality of Fujie lotion.
RESUMEN
Object To isolate the active compounds on reversing multidrug resistance (MDR) of tumor cell from the ethanol extract in the seeds of Cnidium monnieri (L ) Cuss Methods The fractionation directed by bioactivity was carried out with silica gel chromatography and RP HPLC Results Three active coumarins were obtained: imperatorin (Ⅰ), edultin (Ⅱ) and 3′ isobutyryloxy O acetyl columbionetin (Ⅲ) Their sturctures were identified by spectroscopic analysis Conclusion These three compounds have a medium reversing MDR of KBV200 in vitro
