摘要: |
目的 建立番石榴叶中金丝桃苷的HPLC含量测定方法。方法 采用Dikma Kromasil C18色谱柱(4.6 mm×250 mm,5 mm),以甲醇-0.1%磷酸溶液(45∶55)为流动相,流速为1.0 mL·min-1,检测波长为254 nm。结果 金丝桃苷在0.020 48~ 0.204 8 μg内呈良好的线性关系(r=0.999 9),平均回收率为98.4%,RSD为1.5%。结论 本方法简单、准确、重复性好、专属性强,可用于番石榴叶药材及制剂中金丝桃苷的含量测定。 |

Abstract: |
OBJECTIVE To establish a determination method for hyperin in Psidium guajava leaf by HPLC. METHODS HPLC was performed on a Dikma Kromasil C18 column(4.6 mm×250 mm, 5 mm) with methanol-0.1% phosphoric acid solution(45∶55) as the mobile phase at a flow rate of 1.0 mL·min-1, and the detection wavelength was 254 nm. RESULTS It showed a good linearity at the range of 0.020 48~0.204 8 mg(r=0.999 9), and the average recovery of hyperin was 98.4%(RSD=1.5%). CONCLUSION The method is sensitive, accurate, reproducible, specific and could be used to determine hyperin in Psidium guajava leaf. |
