全蝎粉末显微特征主要为两种刚毛及体壁碎片,体壁碎片上有多边形纹理、圆形乳头状突起及毛窝。纸层析用正丁醇—冰醋酸—乙醇—水(4:1:1:2)做展开剂,0.5％茚三酮显色,显3个斑点,只Rf值为0.26、0.34、0.45。纸上电泳爪甲酸—乙酸缓冲液,200V恒压电泳2.5小时,0.5％茚三酮显色,显7个斑点,泳动值为6.4、11.3、12.4、14.1、15.2、17.1、17.9(cm)。紫外光谱测定在258.9nm处显示最大吸收。
The microscopic features of the whole thorium powder are mainly two kinds of bristles and body wall fragments. The body wall fragments have polygonal texture, round papillary protrusions and hair follicles. Paper chromatography was performed with n-butanol-glacial acetic acid-ethanol-water (4:1:1:2) as a developing agent, and 0.5% ninhydrin was developed to show three spots. The Rf value was only 0.26, 0.34, and 0.45. Electrophoresis formic acid-acetate buffer on paper, constant voltage electrophoresis at 200 V for 2.5 hours, color development with 0.5% ninhydrin, 7 spots, 6.4, 11.3, 12.4, 14.1, 15.2, 17.1, 17.9 (cm) . Ultraviolet spectroscopy showed a maximum absorption at 258.9 nm.
