A subspecies of Paeonia mascula (Paeoniaceae) from W. Asia and SE. Europe

The plant from eastern Aegean islands, S. Turkey, Cyprus, Lebanon, Syria and N. Iraq is recognized as a subspecies of Paeonia mascula based on a large quantity of herbarium specimens from the major herbaria in Europe. The subspecies, Paeonia mascula subsp. orientalis (Thiebaut) D. Y. Hong, is characterized by nearly always having some leaflets segmented and the total number of leaflets and segments ranging from (9) 12 to 18 (23); leaflets and segments broadly elliptical to ovate-rounded and usually glabrous or sparsely villous on the lower surface.     

分光光度法测水红花子中花旗松素含量

目的:检测水红花子中花旗松素的含量.方法:采用紫外分光先度法,在常温下(25℃)290nm处,对水红花子乙醇提取物进行吸光度测定.结果:此方法线性范围:0.002～0.01 g/L,花旗松素浓度与吸光度线性关系:y=0.0724x 0.007,r2=0.9986;平均回收率为99.37%,RSD=0.897%.结论:紫外分光光度法测定水红花子中花旗花素合量操作简便、快速和准确度高,具有一定实用价值.
