目的:测定不同产地窝儿七中槲皮素、鬼臼毒素、山奈素的质量浓度。方法:采用DiamonsilC18(4.6 mm×250 mm,5μm)色谱柱,甲醇-0.4%的冰醋酸水溶液为流动相,梯度洗脱;检测波长:290 nm,流速:1.0 mL/min,柱温30℃。结果:不同产地的窝儿七中槲皮素、鬼臼毒素、山奈素的差异较大,其中,眉县红河谷石海产窝儿七中槲皮素的质量浓度最高,为11.50 mg/g;太白县产窝儿七中鬼臼毒素的质量浓度最高,为106.69 mg/g;甘肃天水产窝儿七中山奈素的质量浓度最高,为8.36 mg/g。结论:产地对窝儿七中槲皮素、鬼臼毒素、山奈素有一定的影响。
Objective: To determine the concentrations of quercetin, podophyllotoxin, kaempferol in different producing areas. METHODS: Diamonsil C18 column (4.6 mm × 250 mm, 5 μm) was used as the mobile phase, gradient elution was performed with methanol-0.4% glacial acetic acid. The detection wavelength was 290 nm, the flow rate was 1.0 mL / min and the column temperature was 30 ℃. Results: Quercetin, podophyllotoxin and kaempferol occurred in different areas. Among them, quercetin was the highest concentration of 11.50 mg / g. The highest concentration of podophyllotoxin in Taibai seven was 106.69 mg / g, and the highest concentration was 8.36 mg / g. Conclusion: The origin of Querk seven quercetin, podophyllotoxin, kaempferol have a certain impact.
