用超声波提取、薄层扫描法测定止血定痛片中人参皂甙Ｒｇ１ 的含量， 方法简便， 结果准确。薄层条件为： 含０－２％ ＣＭＣ－ Ｎａ 的硅胶Ｇ 板， ［ 正丁醇－ 乙酸乙酯－ 水（３∶２∶５）］ 上层液－ 甲醇（１０∶１） 为展开剂（ 展开缸预先用氨蒸汽饱和半小时） ， １０ ％ 硫酸乙醇加热显色。扫描波长λｓ ＝ ５３０ｎｍ ，λＲ＝ ７００ｎｍ ， 平均回收率为９６－３８ ％ ， ＲＳＤ 为１－０５ ％ 。
The content of ginsenoside Rg1 in hemostatic and pain tablets was determined by ultrasonic extraction and thin layer scanning. The method was simple and accurate. Thin layer conditions were: Silica gel G plate containing 0-2% CMC-Na, [n-butanol-ethyl acetate-water (3:2:5)] supernatant liquid-methanol (10:1) as developing solvent (Expanded The cylinder was pre-saturated with ammonia vapor for half an hour), and 10% sulfuric acid ethanol heated the color. Scanning wavelength λs = 530nm, λR = 700nm, the average recovery was 96-38%, and RSD was 1-05%.
