ABSTRACT
OBJECTIVE:
To establish HPLC fingerprint of flavonoids from Bauhinia blakeana and to provide reference for harvest, application and quality evaluation of B. blakeana.METHODS:
RP-HPLC method was used to determine the content of flavonoids from 10 batches of B. blakeana from different habitats and in different harvest periods with rutin and quercetin as control. The similarity was calculated using TCM fingerprint similarity evaluation system. The separation was performed on Hypersil ODS C18(250 mm?4.6 mm,5 ?m) column with mobile phase consisted of methanol-0.4% phosphoric acid solution (gradient elution) at flow rate of 0.7 mL?min-1 lasting for 40 min. The UV detection wavelength was set at 360 nm and column temperature was at 25℃.RESULTS:
The results showed that 14 peaks were common. The similarity index of 10 batches B. blakeana samples were between 0.88 and 0.94. The results indicated chemical components were similar but content of the compounds was different.CONCLUSION:
Established HPLC fingerprint of B. blakeana is stable, reliable and reproducible, which is valuable for harvest, application and quality evaluation of B. blakeana.
