目的:建立高速逆流色谱分离纯化新疆圆柏枝叶中的黄酮类成分的方法。方法:以氯仿∶甲醇∶正丁醇∶水(4∶3∶0.5∶2)为溶剂系统,上相为固定相,下相为流动相,在流速2.0 m L/min、转速850 r/min、检测波长254 nm的条件下,对新疆圆柏中的黄酮类成分进行分离纯化。结果:从新疆圆柏提取物中分离纯化得到3个化合物:异槲皮苷(a,91.89%)、槲皮苷(b,98.45%)、槲皮素-3-O-(6″-O-乙酰基)-β-D-吡喃葡萄糖苷(c,95.35%),其中c为首次从圆柏属植物中分离得到的化合物。结论:该法快速简便,能够高效分离新疆圆柏中的黄酮类成分。
Objective: To establish a method for the separation and purification of flavonoids from the branches and leaves of Sabina vulgaris by high-speed countercurrent chromatography. Methods: The solvent system was chloroform: methanol: n-butanol: water (4: 3: 0.5: 2). The upper phase was stationary phase and the lower phase was mobile phase. , The detection wavelength of 254 nm under the conditions of the Sabina vulgaris flavonoids were isolated and purified. Results: Three compounds were isolated and purified from Sabina vulgaris: isoquercitrin (a, 91.89%), quercitrin (b, 98.45%), quercetin-3-O- -acetyl) -β-D-glucopyranoside (c, 95.35%), of which c is the first compound isolated from Sabina; Conclusion: This method is fast and easy, Flavonoids.
