Simultaneous Determination of 8 Flavonoid Glycosides in Sedum bulbiferum by HPLC
OBJECTIVE:To establish a metho d for sim ultaneous determination of 8 flavonoid glycosides in Sedum bulbiferum . METHODS:HPLC method was adopted to determine the contents of kaempferol- 3-O-β-D-glucopyranoside-(1→2)-α-L-glucopy- ranoside-7-O-α-L-glucopyranoside(KGGR),kaempferol-3-O-β-D-glucopyranosyl-7-O-α-L-rhamnopyranoside(KGR),quercetin-3- O-α-L-rhamnose-7-O-α-L-rhamnoside(QRR),BulbiferumosideⅡ,kaempferol-3-O-(6-coumarinyl)-β-D-glucose-(1→2)-β-D-glu- cose-7-O-α-L-rhamnoside(KcGGR),kaempferol-3-O-(2-β-D-glucose)-α-L-rhamnose-7-O-α-L-rhamnoside(KGRR),kaempferol-3- O-α-L-rhamnoside-7-O-α-L-rhamnoside(KRR),kaempferol-3-O-(6″-acetyl-β-D-glucose)-7-O-α-L-rhamnoside(KaGR)in S. bulbi- ferum. The determination was performed on Waters CORTECS C 18 column with mobile consisted of acetonitrile - 0.1% phosphoric acid water solution (gradient elution )at the flow rate of 0.8 mL/min. The detection wavelength was set at 254 nm,and column temperature was 35 ℃. The sample size was 5 μL. RESULTS:The linear range of 8 constituents were 0.013-0.052,0.005-0.018, 0.008-0.031,0.010-0.042,0.009-0.038,0.008-0.030,0.009-0.037,0.032-0.130 μg,respectively(all r were not less than 0.999 0). The limits of detection were 0.08,0.14,0.11,0.21,0.42,0.35,0.23,0.28 μg/mL,respectively. The limits of quantification were 0.25,0.47,0.38,0.69,1.40,1.17,0.77,0.93 μg/mL,respectively. RSDs of precision ,reproducibility and stability tests (24 h) were all lower than 3%(n=6 or n=7). The average re coveries were 99.67%-104.20%(RSDs=0.17%-1.59%,n=6). Average contents of above 8 constituents in 13 batches of samples were 0.893 8,0.312 6,0.490 8,0.964 9,0.751 2,0.502 2,0.606 2, 1.915 7 mg/g(n=3). CONCLUSIONS : The method is simple, acourate and reproducible , and can be used for simultaneous determination of 8 flavonoid glycosides in 才〔2016〕5677) S. bulbiferum .
