云南省德钦县、维西县和贡山县有相当多的胡黄连分布,其原植物经鉴定为玄参科植物 Picrorrhizascrophulariaeflora Pannell。我们测定滇产胡黄连的苦味度比值为70(进口胡黄连为70),其水浸出物为45.92%(进口胡黄连为35.82%),其60%乙醇浸出物为55.83%(进口胡黄连为40.78%),故认为二者同样可供药用。为了进一步明确滇产胡黄连与进口胡黄连在化学成分方面是否相同,进行了下述的实验比较。毛管象的测定:取胡黄连粉末4g,加60%乙醇,在水浴上回流30分钟,放冷,滤过。滤液即为检液,按2、4、8,16、32倍稀释于小烧杯中,取 Whatman
Deqin County, Weixi County and Gongshan County in Yunnan Province have a considerable number of distributions. The original plant was identified as Picrorrhiza scrophulariaeflora Pannell. We measured the bitterness ratio of peperostracene in production of 70 (Imported Huhuanglian was 70), its water extract was 45.92% (35.82% for imported Huhuanglian), and its 60% ethanol extract was 55.83% (Imported Huhuanglian was 40.78%), it is considered that the two are also available for medicinal purposes. In order to further clarify whether the chemical composition of Huhuanglian and imported Huhuanglian is the same, the following experimental comparisons were conducted. Determination of capillary images: Take 4g of Huhuanglian powder, add 60% ethanol, reflux on a water bath for 30 minutes, let cool and filter. The filtrate is the test solution, diluted 2,4,8,16,32 times in a small beaker. Whatman
