Hypothesis

The study aims to enhance the HPLC separation and validation of astilbin in Lysiphyllum strychnifolium stems using Box–Behnken Design.

Conclusion

The optimized HPLC method significantly reduced the retention time of astilbin to 12.10 minutes, achieving a 68.57% reduction in analysis time.

Supporting Evidence

  • The optimal HPLC settings resulted in a 26-minute reduction in working time.
  • The limit of detection for astilbin was found to be 0.10 μg/mL.
  • The calibration curve showed excellent linearity with an R2 value of 0.9991.
  • Recovery values ranged from 95.56% to 105.57%, confirming the method's accuracy.
  • The method demonstrated high precision with intraday RSD values from 0.069% to 1.892%.
  • The optimized method is suitable for routine applications in the pharmaceutical and herbal industries.

Takeaway

The researchers found a faster way to separate a plant compound called astilbin, making it easier to study and use.

Methodology

The study used Box–Behnken Design to optimize the HPLC separation process by adjusting the percentage of acetonitrile, flow rate, and temperature.
