摘 要:
[目的]采用高速逆流色谱法(HSCCC)分离纯化雪白睡莲花中的酚类成分。[方法]HSCCC分离过程分为两步,分别采用乙酸乙酯∶甲醇∶水(4∶1∶5)和乙酸乙酯∶正丁醇∶水(4∶1∶5)两个体系,固定相均采用上相,流动相均采用下相,流速为2.0 m L/min,主机转速设定为850 r/min,紫外检测波长为254 nm。高效液相色谱(HPLC)检测纯度。[结果]第一步从200 mg的睡莲花提取物中分离得到异槲皮苷(I,41.4 mg)、紫云英苷(II,40 mg)和一混合物85 mg;第二步从混合物中分离纯化得到isostrictiniin(III,50.1 mg)和烟花苷(IV,26.3 mg),上述4种物质的纯度分别为73.53%、92.42%、82.36%和85.65%。[结论]HSCCC可快速的分离纯化雪白睡莲花中的酚类成分。

摘 要:
[Objective] To isolate and purify phenolic constituents from Nymphaea candida Presl by high-speed counter-current chromatography( HSCCC). [Methods] HSCCC was employed to separate phenolic compounds from N. candida with two steps. Two solvent systems were ethyl acetate ∶ methanol ∶ water( 4 ∶ 1 ∶ 5) and ethyl acetate ∶ n-butanol ∶ water( 4 ∶ 1 ∶ 5). HSCCC was executed under the conditions of2. 0 m L / min flow rate,850 r / min rotation speed and 254 nm detection wavelength. The purities of compounds were determined by HPLC.[Result]In the first separation step,isoquercitrin( I,41. 4 mg),astragalin( II,40 mg) and mixtures of III and IV( 85 mg) were extracted from 200 mg sample. In the second step,mixtures of III and IV were obtained: isostrictiniin( III,50. 1 mg) and nicotiflorin( IV,26. 3 mg).The purities of these compounds were determined as 73. 53%,92. 42%,82. 36% and 85. 65% by HPLC. [Conclusion]Phenolic compounds from N. candida can be quickly isolated and purified by HSCCC.
