中文摘要 | a novel, sensitive and selective hplc-flc method coupled with pre-column derivatization was developed for amino acid determination in hippophae rhamnoides l. fruit from qinghai-tibetan plateau. the method is based on the derivatization reaction of amino group with 2[2-(dibenzocarbazole)-ethoxylethyl chloroformate (dbcec) and the derivatives could be measured at 390 nm (excitation wavelength: 300 nm). detection limits (calculated as the signal-to-noise ratio 3:1) were 12.85-51.68 mol for the labeled amino acids. linearity was observed with coefficients > 0.9991 and the recoveries ranged from 92.7-105.4 %. results in this research showed that the amount of essential amino acids accounted for 70.42 % of free amino acids and 22.68 % of the total amino acids, respectively, which benefits people's health through drinking the juice or eating the related products. proline was dominating among free amino acids in samples, which plays a vital role for hippophae rhamnoides l. in resisting to drought, tolerating soil salinity and lowing temperature in qinghai-tibetan plateau. |
