柴胡多见于保健强壮、消炎排脓等处方中,含有柴胡皂甙a、c、d等。1 HPLC定量法——柴胡中柴胡皂甙a、c、d的定量试剂及标准品氨水-甲醇溶液,即取1ml浓氨水加甲醇定容至20ml。柴胡皂甙a、c、d标准品为生药实验用,系和光纯药产。实验材料 9个柴胡样品。标准溶液分别精密称取柴胡皂甙a(8mg)、c(10mg)、d(10mg),用甲醇溶解并定容至20ml即可。实验方法精密称取0.5g通过48目筛
Bupleurum is more common in health care, anti-inflammatory pus and other prescriptions, containing saikosaponin a, c, d and so on. 1 Quantitative HPLC method - quantitative reagents for saikosaponin a, c, and d in Bupleurum chinense and standard aqueous ammonia-methanol solution, that is, 1 ml of conc. ammonia water and methanol are added to a volume of 20 ml. The saikosaponin a, c, and d standards are used for crude drug experiments and are produced by Wako Pure Chemical Industries. Experimental material 9 samples of Bupleurum. The standard solution was accurately weighed, respectively saikosaponin a (8mg), c (10mg), d (10mg), dissolved in methanol and set the volume to 20ml. The experimental method accurately weighed 0.5g through 48 mesh sieve
