Abstract:

Objective: To establish a high performance liquid chromatography (HPLC) method for the determination of
proanthocyanidins in lotus seed shell extract. Methods: HPLC analysis was carried out using Diamonsil C18 (4.6 mm × 250 mm,
5 μm), and the mobile phase consisted of methanol-water-formic acid-isopropyl alcohol (13:73:8:6, V/V) at a flow rate of
1.0 mL/min. The detection wavelength was set at 525 nm, the column temperature was set at 35 ℃, and the injection volume
was 10 μL. Results: A good linearity of proanthocyanidins was achieved in the range of 37.6–300.8 μg/mL (r = 0.999 5).
The average recovery was 99.2%, with relative standard deviation (RSD) of 0.30%. Conclusion: This method is simple,
reproducible, accurate and reliable and thus can be used for quality control of lotus see shell extract.

Key words: lotus seed shell extract, proanthocyandins, high performance liquid chromatography (HPLC)
