摘　　要：本文用浓硫酸—苯酚法测定了胶囊中南沙参多糖的含量，工作曲线线性关系良好ｒ＝０．９９９４７；平均回收率１０１．６６％；ＲＳＤ＝２．７４％；精密度高；日内差异１．４９％；月间差异２．０３％；最低检测限量为９．５０μｇ／ｍｌ，３６小时内稳定性好。本法可作为胶囊中南沙参多糖含量测定及有关质量控制的一种准确、可行的方法。The Radix Adenophorae Polysaccharides(RAPS)in Capsule is meadured with dense sulphwrue alid Phenol methid The result showed that this method adopt not only the studly of the concentration of(RAPS) but alse the control of relatively quality of RAPS in capsule.linage of work curve:r=0.99947;Mean rate of recovery:101.66%,RSD:2.47%;Differense in one day:1.49%and that of during days:2.9%;Minimun measure limit dose:9.50μg/ml.the stability of method in 36 hours is good.
