title: [Determination of hyperin in Sanguisorba Officinalis L. by high performance liquid chromatography].
abstract: An HPLC method for the determination of hyperin in Sanguisorba officinalis L. was investigated. 0.5 g of dried powdered crude drug was weighed accurately in a 50 mL volumetric flask added with 40 mL methanol, supersonicated for 30 min and then made up to volume with methanol. The sample solution was separated on a Shim-pack ODS column(6.0 mm i.d. x 150 mm, 5 microns) with methanol-0.025 mol/L phosphoric acid (adjusted to pH 3.0 by using triethylamine)(50:50) as the mobile phase and detected at UV-370 nm. Calibration curve of hyperin was obtained for the concentration range of 0.046-0.2 microgram. The corresponding regression equation was Y = 154 x 10(4) X-0.28 x 10(4), r = 0.9998. The recovery was 98.7% and relative standard deviation was 1.9%. The results showed that this method is simple, specific and accurate.
