Objective: To study the isolation and determination of verbascoside from Callicarpa longissima. Method: Verbascoside was extracted by 95% ethanol
isolated and purified by column chromatography and PHPLC from the stem and branch of C. longissima. A HPLC method was set up to determine the content of verbascoside in C. longissimae
using ECOSIL ODS-EXTEND(4.6 mm×250 mm
5 μm) column
and acetonitrile -0.2% phosphoric acid water solution as the mobil1-9e phase
the UV detection wavelength was at 334 nm
with the flow rate of 1.0 mL·min-1 at room temperature. Result: A good linear was obtained in the range of 0.051 9-0.829 6 μg and the average recovery was 99.13% (RSD 1.80%). Conclusion: Verbascoside was isolated from C. longissima for the first time.The method can provide useful references to quality control of C. longissima.
