百部生药学研究——Ⅸ.中国百部属植物块根中总生物碱的测定与评估

An acid-dye colorimetric method was reported for the determination oftotal alkaloids in 53 samples of Baibu drugs from their growing destricts in 14 provincesand municipalities and its average recovery and its linear range were 96. 1% ( CV <4%)and 20～150μg respectively. The relationship between the total alkaloid content, geogra-phical origins and morphology were discussed. The results showed that: 1. the content of totalalkaloids of stemona was 0.26～3. 1 %; 2. that of Stemona sessilifolia was 0.26～2.17%with the highest content of the sample from Nanyang country in Henan Province; 3.that of S. japonica was 0.83～1.43%; 4. that of S. tuberosa was 0.53～3.1% with thehighest content of sample from Hengyang in Hunan Province; 5.that of S.parviflora was 0.22～0.74% with the highest content of sample from Qongzhong in Hainan Province;and 6.thatof more yellow, solider and stronger samples was higher than that of any other samples.Howerver, that of all bigger samples in shape was not higher than that of smaller ones.     

麦冬类中药的药源调查和商品鉴定

对我国麦冬类中药分布较广的浙江、四川、湖北、贵州、云南、福建、江苏、安徽等省进行药源调查,经分类学研究,已鉴定出以麦冬或野麦冬为名的有沿阶草属(Ophiopogon Ker-Gawl.)和山麦冬属(Liriope Lour.)植物23种和3变种。对从24个省,市(区)收集到的69件麦冬样品进行了商品鉴定,发现有9种2变种沿阶草属和山麦冬属植物的块根,并发现一种伪品,基本弄清了我国麦冬类中药的主流商品种类和产销情况。
