RP-HPLC determination of two hosenkosides in seeds of Impatiens balsamina L.
To determine two hosenkosides(hosenkoside K and Hosenkoside A)in the seeds of Impatiens balsamina.
METHODS AND RESULTS:
:Using RP-HPLC with ELSD method.Separation was carried out on Eclipse XDB-C18 column(4.6 mm×250 mm,5 μm).A linear solvent gradient was used,with a mobile phase of methanol-water(0-22 min,50∶50;22-50 min,54∶46).The flow rate was 0.8 mL·min-1 at 25 ℃.The gas(air)flow rate was 2.5 L·min-1 and the temperature of drift tube for measurement was 89 ℃.The linearity was in the range of 5-20 μg for hosenkoside K and A,and the correlation coefficients(n=6)were 0.9995 and 0.9992 respectively;The average recoveries(n=6)for hosenkoside K and A were 98.0%(RSD=1.3%)and 98.0%(RSD=1.3%)respectively.
CONCLUSIONS:
This method is accurate,reliable and reproducible for determination of hosenkoside K and A in the seeds of Impatiens balsamina.
