It has been reposed (8, 9, 10) that by boiilng sulfonic acid type ion exchage resin with certain plant drugs, the alkaloids in the latter could be transferred quantitatively to the resin and could be determined subsequently In this paper a1e reported the results obtained with ion cxdlange resms nt sulfonic acid typc and an ion exchange fabric of phosphoric acid type Nine to ten kinds of plant drugs were studied in each casc Five uf theset Areca catechu L., Fritillaria thunbergii Miq., Stemona lobgroga Lout., Sopholra flavescens Ain. And Leonurus heteropbyllus Sweet, could be determined by ion exchange rCSIDS and tour, namelv. Atropa belladonna L., Areca calecku L., Leonurus hetcrophyUus Sweet and Coptis chinensls Franch, by thc ion exchange fabric. Where the method worked, it was simple ranid and gave the same results as those obtalned with the pharmacopeiacal methods.

本文研究了在不同pH的底液中，一些生物碱（鸟头碱、小黎碱、番术蟹础、幸可宁、白届菜碱、那可汀、奎宁）与四苯硼钠闻反应条件，观察了二者形成沉淀的关系，通过试验，提出在进行生物蹴滴定时，根据生物碱的性强强弱，可计算出底液适宜的pH，井提出以四苯硼钠滴定生物碱的安培方法。

洋地黄叶提出物在甲酰胺作固定相的畦藻土薄层上，甩氧仿-丙酮-醋酸乙酯-乙醇-甲酰胺（8∶2∶0.5∶0.5∶饱和），破氯仿-丁醇-甲酰胺（9∶1∶饱和），破氢仿-醋酸乙酯-革-甲酰胺（1∶3∶2∶饱和）作展开剂，分别分离毛花洋地黄-级甙，紫花洋地黄-般甙，或二级甙。晨开后的板，于100℃烤去甲酰胺，碘蒸气显点，用吸取嚣将色点吸下，以咕吨氢酵的冰醋酸溶液洗脆。洗脱菔申加凡-定盘盐酸后，显色稠定。冒测定了六种纯强心甙的回牧率，除羟基洋地盘毒甙因色点有拖尾，结果儡低，为87.7%外；毛花洋地黄甙甲、乙、丙，洋地黄毒甙，异羟基洋地蒉毒甙等的回收率均在94.9-97.6%间，标准偏差0.6-2.6%。

本文用GLC等方法鉴定和鉴定了海州香薷挥发油中对聚撒花素（10.43%），百里香酣（30.05%），香荆拌酚（33.39%），ɑ-反式-香柠檬烯（1.64%）等12个成分，井与川香薷挥发料I的成分进行了分析比较。
