Atractylodis rhizoma, is the dried rhizomes of Atractylodes lancea (Thunb.) DC. or A. chinensis (DC.) Koidz. Both of two are pharmacologically and economically important, while with differences in efficacy. Therefore, an authentication system is vital for evaluation the quality and discrimination adulteration of Atractylodis rhizoma. Fructooligosaccharides (FOS), which are regarded as functional ingredients in Atractylodis rhizoma, have not been used for quality control of Atractylodis rhizoma for shortage of reference compounds. A HPLC-ELSD method was developed for the quantification of FOS in Atractylodis rhizoma. And chemometrics analysis showed that 2 markers including content of degree of polymerization (DP) 12 and total content of DP 3-15 could be used as the main distinctive elements for quality evaluation of Atractylodis rhizome. Actually, the separation and purification of high DP FOS, such as DP 12, is still a challenge because of high polarity. Then DP 5-based qualification evaluation was investigated for quality control of Atractylodis rhizoma. The results showed that A. lancea and A. chinensis could be clearly separated. DP 5-based quantification method was credible and effectively adopted for solving the shortage of reference compounds and improving the quality control of Atractylodis rhizoma

基于寡糖的白术质量评价及简化质量控制的策略

Atractylodis rhizoma，是 Atractylodes lancea (Thunb.) DC 的干燥根茎。或 A. chinensis (DC.) Koidz。两者在药理学和经济上都很重要，但功效不同。因此，鉴定体系对于评价白术的质量和鉴别掺假至关重要。低聚果糖（FOS）被认为是白术的功能成分，由于缺乏对照品，尚未将其用于白术的质量控制。建立了 HPLC-ELSD 方法用于白术中 FOS 的定量。化学计量学分析表明聚合度(DP) 12 含量和DP 3-15 总含量2个标志物可作为白术品质评价的主要特征要素。实际上，由于高极性，高 DP FOS（如 DP 12）的分离和纯化仍然是一个挑战。然后研究了基于DP 5的资格评价用于白术的质量控制。结果表明，茅草和中华茅草可以明显分离。采用基于DP 5 的定量方法可靠有效地解决了对照品短缺问题，提高了白术的质量控制
