| 英文摘要 | For the first time an rp-lc method with diode-array detection has been developed for simultaneous analysis of three flavonoids [rhamnocitrin-3-o-beta-d-galactopyranoside-4'-o-beta-d-glucospyranoside (rgg), rhamnocitrin-3-o-beta-d-galactopyranoside (rg), and 10-methoxymedicarpin (mc)] in a methanol extract of oxytropis kansuensis bunge whole plant. separation was achieved on an ods column within 18 min. the effect of mobile phase ph on separation of the three flavonoids was investigated. compared with relative errors obtained by use of least-squares linear regression and logarithmic regression for data processing, weighted least-squares linear regression was more accurate. response was a linear function of concentration in the ranges 0.0091-3.4, 0.013-4.9, and 0.0085-3.2 mg ml(-1) for rgg, rg, and mc, respectively, with correlation coefficients > 0.9997. the amounts of the three flavonoids in o. kansuensis bunge were successfully analyzed with satisfactory repeatability and recovery. |
