ABSTRACT

OBJECTIVE:

To establish a method for simultaneous determination of hyperoside,quercitrin,luteoloside, kaempferol,quercetin,rutin,luteolin and isorhamnetin in total flavanones of Sedum sarmentosum Bunge.

METHODS:

UPLC-MS/MS method was adopted. The determination was performed on ZOBAX SB C18column with mobile phase consisted of methanol-5 mmol/L ammonium formate aqueous solution(4555,V/V)at the flow rate of 0.4 mL/min. The column temperature was 30 ℃, and sample size was 2 μL. The electrospray ionization source(ESI)was used;ion source temperature was 400 ℃;desolvation temperature was 300 ℃;desolvation gas flow was 600 L/h;capillary voltage was 3 000 V;nebuliser pressure was 45 psi;the work mode was multiple reaction monitoring mode;detection mode was negative ion mode. The established method was used to determine the contents of 8 components in 3 batches of total flavanones of Sedum sarmentosum Bunge.

RESULTS:

The linear ranges of hyperoside,quercitrin,luteoloside,kaempferol,quercetin,rutin,luteolin and isorhamnetin were 10.0-640.0,0.5-32.0, 4.5-288.0,8.0-512.0,50.0-3 200.0,2.0-128.0,12.5-800.0 and 25.2-1 612.8 ng/mL(r≥0.991 4),respectively. The limits of detection were 5.0,0.25,2.25,4.0,25.0,1.0,6.25 and 12.6 ng/mL,respectively.The limits of quantitation were 10.0,0.5,4.5, 8.0,50.0,2.0,12.5 and 25.2 ng/mL,separately. RSDs of precision,stability(24 h)and reproducibility tests were no more than 4.3%(n=6). The recoveries were 95.9%-100.6%,and RSDs were 1.5%-3.8%(n=6). The contents of hyperoside,quercitrin, luteoloside,kaempferol,quercetin,rutin,luteolin and isorhamnetin in 3 batches of total flavanones of Sedum sarmentosum Bunge were 507.88-560.37,42.95-50.36,63.52-71.80,1 695.10-1 753.27,10 569.28-10 612.99,25.76-30.13,2 795.22-2 877.43 and 4 869.55-4 971.30 μg/g,respectively.

CONCLUSIONS:

The established method can be used for simultaneous determination of 8 components in total flavanones of Sedum sarmentosum Bunge.
