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.
