摘要
通过参数优化,建立了HPLC法同时测定李果实中5种花色苷(飞燕草素-3-葡萄糖苷、飞燕草素-3-芸香糖苷、矢车菊素-3-葡萄糖苷、矢车菊素-3-芸香糖苷、芍药素-3-葡萄糖苷)含量的方法,并比较了HPLC法与p H值示差法在测定李果实花色苷总量上的差异。结果表明:以乙腈-水(0.3%磷酸)为流动相,梯度洗脱,检测波长为510 nm,50 min内可实现5种花色苷的完全分离,线性范围为1~100μg·ml-1(R~2=0.9980~0.9997),加样回收率为97.34%~103.17%、RSD为0.83%~1.24%。HPLC法与p H值示差法测定李花色苷总含量的对比结果表明,两者间的差距与花色苷含量有关,花色苷含量越高,两者相差越大,且HPLC法的测定值较高;相反,花色苷含量越低,两者相差越小,且HPLC法的测定值较低。
A reverse ph ase HPL C method was utilized to investigate anthocyanin gategories( delphin-3-glucoside, delphin-3-richinoside, cyanidin-3-glucoside, cyanidin-3-richinoside and peonidin-3-glucoside) and content in fruits of different plum cultivars.The total anthocyanin content in plum fruit was measured by HPLC method and p H differential method, respectively and the differences between two methods were compared. The results showed that the anthocyanin gategories were thoroughly separated within 50 min under the condition of using acetonitrile-water(contained 0.3% phosphoric acid) as mobile phase with gradient elution at a detection wavelength of 510 nm. The method exhibited a linear range from 1 to 100 μg·ml-1( with the correlation coefficients ranged from0.9980 to 0.9997), the recovery rate was from 97.34% to 103.17%, and the RSD was 0.83% to 1.24%. There was remarkable difference between HPLC method and p H differential method for the determination of total content of anthocyanin. The results also showed that the difference was related to the content of anthocyanin. If a cultivar contained more anthocyanin, the value of HPLC method was much higher than that of p H differential method; on the contrary, if a cultivar contained litter anthocyanin, the values became close to each other, and even the value of HPLC method was less than that of p H differential method.
