摘  要:
以黑刺菝葜为试材,应用紫外可见分光光度法,研究测定其6-酮型甾体皂苷类化合物含量的方法;以LG-C为标准品,依据显色剂对LG-C反应的专属性和灵敏度,确定紫外可见分光光度法的显色体系和最大吸收波长;在单因素试验的基础上,通过星点设计-响应面法,确定最适显色反应条件。结果表明:紫外可见分光光度法的显色体系为茴香醛-硫酸法Ⅱ,最大吸收波长为429nm;最佳显色温度82.4℃,反应时间24min,显色剂用量1.2mL。优化反应条件后,在7.51~50.90μg范围内,LG-C与吸光度值呈良好线性关系,r=0.996 9;平均加样回收率为103.37%,RSD 2.2%。该方法灵敏度高、专属性强,重复性好,可以作为黑刺菝葜中6-酮型甾体皂苷含量的测定方法。

摘  要:
To develop a method for the determination the contents of 6-ketone steroidal saponins fromSmilax scobinicaulis C.H.Wright,using LG-C as standard substance,different chromogenic agents,the optimal UV-VIS spectrophotometry and the optimize the chromogenic condition were studied.The results showed that the proposed method was anisaldehyde sulphuric acid Ⅱin the circumstances,and,the maximum absorption wavelength was 429 nm.The optimal temperature was 82.4 ℃,the best reaction time was 24 min,and 1.2mL chromogenic agent was fitted.The calibration curve of LG-C showed good linearity in the range of 7.51-50.90μg,with r=0.996 9.The recovery was detected to be 103.37%,with RSD being 2.2%,respectively.The established colorimetric method provided sensitive,specific and accurate for determination of 6-ketone type steroidal saponins in Smilax scobinicaulis C.H.Wright.
