Polygonum capitatum Buch.Ham.ex D.Don is a commonly used medicine in Zhuang people’s settlements,which has antipyretic,wind and evil-dispelling,dehumidifying and analgesic effects.The research on the chemical composition of P.capitatum began in the 1980 s.Modern scientific research has shown that it has antibacterial,cooling and blood sugar lowering effect.In order to better develop and utilize P.capitatum,this paper reviewed the progress of the chemical composition and pharmacological research of P.capitatum.

贵州省野生头花蓼的品质评价

目的:综合评价贵州不同产地野生头花蓼的品质。方法:采用分子鉴定法、红外光谱法、高效液相色谱法对贵州5个不同产地的野生头花蓼进行品质评价。结果:分子鉴定对比各个产地的头花蓼样品扩增ITS-2序列完全相同;运用聚类分析处理中红外图谱的结果为:剑河县柳川镇关口村6组所产头花蓼与安顺市龙宫镇克马村的头花蓼品质相近;剑河县久仰乡久丢村3组、剑河县南明镇凯寨村的头花蓼品质相近;剑河县太拥镇九仪村与其它几个产地的品质相差较远;不同产地头花蓼中槲皮素、山奈酚含量有明显差异,除贵州省剑河县太拥镇九仪村样品外,其余样品均达到药用要求。结论:贵州野生头花蓼的品质如下:安顺市龙宫镇克马村的头花蓼品质较优,剑河县久仰乡久丢村3组、剑河县柳川镇关口村6组、剑河县南明镇凯寨村次之,剑河县太拥镇九仪村品质有所退化,品质较差。

头花蓼盆炎颗粒的喷雾干燥工艺研究

目的：优化苗药头花蓼盆炎颗粒的喷雾干燥工艺。方法：用单因素考察法优选辅料种类和比例，用正交试验法对影响喷雾干燥的因素（浸膏相对密度、进风温度、进料速度）进行优选。结果：最佳工艺参数为：按5％的比例加入可溶性淀粉到相对密度为1．10的流浸膏中，进风温度230℃，进料速度40～50mL·min^-1。结论：该工艺合理、稳定，为工业化生产提供了实验依据。
