摘要
目的:建立HPLC法测定濒危野生药用植物中华补血草中槲皮素和木犀草素含量的方法,为中华补血草的质量控制提供理论依据。方法:采用高效液相色谱法同时测定中华补血草中槲皮素和木犀草素的含量。色谱柱:TURNERKromasilTMC18柱(250iTlrn×4.6mm,5μm),流动相为甲醇:0.2%o磷酸溶液(55:45)进行等度洗脱,流速为1ml·min-1,检测波长为360nm。结果:槲皮素在浓度0.92-92μg·ml-1范围内有良好的线形关系,相关系数r为0.9996,平均加样回收率为98.87%,RSD为1.68%(n=6)。木犀草素在0.412~41.2μg·ml-1范围内有良好的线形关系,相关系数r为0.9998,平均加样回收率为99.33%,RSD为1.89%(n=6)。结论:方法简便可行、灵敏准确,可作为我国沿海野生中华补血草质量评价的方法之一,该研究对于保存中华补血草野生品种相关资料。
ABSIllACT:OBJECTI~'E To establish a determination method for the contents of quercetin and luteolin in Limonium sinense (Girard) Kuntze by HPLC. METHODS TURNER KromasilTMGscolumn(250 ~ 4. 6 mm, 5 /~m) was used, the mobile phase was consisted of methanol: 0. 20/00 phosphoric acid(55:45), the flow rate was 1 ml.min 1 and the detection wavelength was set at 360 nn% Column temperature was 30~C. ~ULTS Quercetin was linear over the concentration range of 0. 92 - 92/~g. ml- (r = 0. 999 6), the average result of recovery was 98. 870/oo and RSD was 1.68~ (n = 6). Luteolin was linear over the concen tration range of 0. 412 - 41.2/,g-ml ~ (r= 0. 999 8), the average result of recovery was 99. 33~//00 and RSD was 1.89%0 (n = 6).CONCLUSION The proposed method is simple, highly sensitive, precise, accurate and can be used for reliable quantitation and evaluation of Limonium sinense (Girard) Kuntze.
