摘要

目的:研究硫黄熏蒸对党参二氧化硫残留和炔苷含量的影响,为科学合理评价党参质量提供参考.方法:以 208 批次党参为研究对象,分别采用酸碱滴定和高效液相色谱法研究了硫黄熏蒸对二氧化硫和炔苷含量的影响,同时通过模拟硫黄熏蒸探究硫熏时间对炔苷含量的影响.结果:二氧化硫含量不合格率达到 7.21%,二氧化硫含量超过 600 mg/kg的样品批次占比达到5.77%.此外,硫熏时间延长,党参炔苷含量显著下降,平均值由0.213 6 mg/g下降至0.128 5 mg/g.结论:硫黄熏蒸时间延长,导致党参二氧化硫含量上升,炔苷含量下降,为保障市场党参质量,在控制党参二氧化硫残留量的同时,应加强对党参炔苷含量的控制.

Abstract

Objective:The effects of sulfur fumigation on sulfur dioxide residue and alkyne glycosides content of Codonopsis pilosula are studied,in order to provide a reference for the scientific and reasonable evaluation of the quality of Codonopsis pilosula.Methods:208 batches of Codonopsis pilosula are used as research objects,and the effects of sulfur fumigation on the content of sulfur dioxide and alkyne glycosides are studied using acid-base titration and high-performance liquid chromatography,respectively.Meanwhile,by simulating sulfur fumigation,the effect of sulfur fumigation time on the content of alkyne glycosides is explored.Results:The results show that the unqualified rate of sulfur dioxide content reached 7.21%,and the proportion of sample batches with sulfur dioxide content exceeding 600 mg/kg reached 5.77%.In addition,the sulfur fumigation time is prolonged,and the content of Codonopsis pilosula alkyne glycosides significantly decreased,with an average value decreasing from 0.213 6 mg/g to 0.128 5 mg/g.Conclusion:The prolonged sulfur fumigation time leads to an increase in sulfur dioxide content and a decrease in alkyne glycoside content in Codonopsis pilosula.Therefore,in order to ensure the quality of market Codonopsis pilosula,while controlling the residual sulfur dioxide in Codonopsis pilosula,it is also necessary to strengthen the control of the content of alkyne glycosides.
