目的 梳理并展望黄花菜采后贮藏保鲜及其活性成分提取的新技术和新方法，以期为黄花菜产业发展提供理论依据。方法 对近年来黄花菜保鲜贮藏方法进行综述，包括冷藏保鲜、生物化学保鲜和辐射保鲜等，并对黄花菜中的多糖、黄酮、多酚等活性成分的提取方法进行总结。结果 选择适宜的保鲜技术可以在一定程度上延长黄花菜的贮藏期，有助于黄花菜产业健康发展;活性成分提取研究报道主要集中在几种黄酮类与多酚类的成分上，提取技术以微波提取法、超声提取法和溶剂萃取法为主。结论 单一保鲜技术的应用对延长蔬菜贮藏期的效果有限，保鲜技术的综合应用才是今后黄花菜保鲜的发展方向，黄花菜活性成分的提取方法以及提取物的功能验证方面研究还不够系统。

The work aims to sort out and look forward to the new technologies and methods that might be used in the postharvest storage and the bioactive components extraction of daylily (Hemerocallis citrina Baroni), so as to provide theoretical basis for the development of daylily industry. The technologies used to store fresh daylily in recent years were summarized, including low temperature preservation, biochemical preservation and irradiation preservation. Then, the extraction methods of polysaccharides, flavonoids, polyphenols and other bioactive components in daylily were reviewed. The suitable preservation technologies selected for daylily could extend the storage period of daylily to a certain extent and contribute to the healthy development of daylily economy. The research reports on the extraction of bioactive components mainly focused on several flavonoids and polyphenols and the extraction methods mainly included microwave extraction, ultrasonic extraction and solvent extraction. The application of a single preservation technology has limited effect on extending the storage period of daylily and the integrated application of preservation technologies is the development direction of future fresh daylily storage. The research on the extraction methods of bioactive components and functional verification of extracts from daylily is not systematic enough.
