摘 要:目的:考察独一味不同提取物中总环烯醚萜苷、总黄酮和总苯乙醇苷的含量。方法:独一味水提物经聚酰胺和大孔树脂通过串联及并联方法,分别富集得到水洗脱物、70%乙醇溶液洗脱物Ⅰ(70%乙醇溶液洗脱聚酰胺柱)、70%乙醇溶液洗脱物Ⅱ(70%乙醇溶液洗脱大孔树脂柱),采用一阶导数紫外分光光度法测定总环烯醚萜苷的含量;双波长紫外分光光度法、硝酸铝-亚硝酸钠显色分光光光度法测定总黄酮和总苯乙醇苷的含量。结果:建立的一阶导数紫外分光光度法测定总环烯醚萜苷的含量,在252 nm波长处加样回收率为104.40%,RSD分别为0.64%;建立的紫外分光光度法可以测定总黄酮和总苯乙醇苷的含量,总黄酮在268,363 nm波长处平均加样回收率分别为96.23%,104.48%,RSD分别为7.27%,3.61%;总苯乙醇苷在332 nm波长处加样回收率为100.26%,RSD 2.92%。结论:一阶导数紫外分光光度法测定总环烯醚萜苷的含量可行;紫外分光光度法可以测定总黄酮和总苯乙醇苷的含量。Objective: To investigate determination of total iridoid glycoside,total flavonoids and total phenethanol glycosides from different extractive of extract of Lamiophlomis rotata. Method: Water extract of L. rotata were separated and enriched obtain water eluate and 70% ethanol solution eluateⅠ(70% ethanol solution eluted polyamide column),70% ethanol solution eluate Ⅱ (70% ethanol solution eluting macroporous resin column) by polyamide and macroporous resin. Total iridoid glycosides ingredients were assayed by the first derivative spectrophotometry;the total flavonoids and total benzene glycosides were assayed by dual wavelength UV spectrophotometry,aluminum nitrate-sodium nitrite UV spectrophotometry. Result: Recoveries of the total iridoid glycosides was 104.40%,RSD was 0.64% at 252 nm wavelength by the first derivative UV spectrophotometry. Recoveries of the total flavonoids were 96.23% and 104.48%,RSDs were 7.27% and 3.61% at the 268 nm and 363 nm wavelengths by UV spectrophotometry. Recoveries of the total benzene glycosides was 100.26%,RSD was 2.92% at 332 nm wavelength. Conclusion: The first derivative ultraviolet spectrophotometry can determine the total iridoid glycosides. The ultraviolet spectrophotometry can determine the total flavonoids and total benzene glycosides.
