我们于1973～1974年对我省不同产地及不同生长期的北三豆根的总生物硷含量进行了分析,现将结果报告如下: 一、测定方法:取北山豆根生药粉末(过60目筛)6g,置于带磨口塞三角瓶中,加入苯60ml,振摇10分钟,再加入10％氨水5ml,随时振摇二小时,静置12小时,取上清液用脱脂棉过滤,取3Oml(相当生药3g)移于分液漏斗中,用0.5％H_2SO_4分次振摇提取共五次(每次用 From 1973 to 1974, we analyzed the total contents of bio-germanium in different producing areas and different growing seasons in our province. The results are reported as follows: I. Measurement method: Take Beishan bean root crude drug powder (60 mesh sieve) ) 6g, placed in a grinding stopper triangle bottle, add benzene 60ml, shake 10 minutes, then add 10% ammonia 5ml, shake at any time for two hours, let stand for 12 hours, take the supernatant with cotton wool filter, take 3Oml (Some crude drug 3g) was transferred to a separatory funnel and extracted five times with 0.5% H_2SO_4 shaking (each use
