“…This irregular terpene has a floral fruity aroma and has been documented in more than 45 families of seed plants, including Rosaceae, Malvaceae, and Apiaceae (Knudsen et al, 2006;Widjaja et al, 1996). At least nine volatiles from this study were reported by Jiao et al (2016), including b-myrcene, (E)-b-ocimene, b-linalool, allo-ocimene, b-caryophyllene, a-farnesene, (E)-nerolidol, phenylethyl alcohol, and indole. Lin et al (2003) also reported phenylethyl alcohol, as well as acetoin, 2-ethyl-1-hexanol, and benzaldehyde.…”

“…Terpenoids dominated the fragrance profile of every daylily evaluated in this study. Similarly, Jiao et al (2016) reported that terpenoids represented more than 80% of the total volatiles released, with (E)-b-ocimene appearing in the volatile profile of 45 of the 46 daylilies they evaluated. This compound is one of the most common components of floral scent, occurring in more than 70% of seed plant families (Knudsen et al, 2006).…”

“…Over the years, the focus on flower color, pattern, and form in daylily breeding resulted in at least one unfortunate, unintended consequence: the loss of fragrance. Although a number of the daylily species have noticeable, distinct fragrances, those fragrances are thought to be greatly reduced or largely absent in modern hybrids (Jiao et al, 2016). Loss of fragrance is not a phenomenon unique to daylilies.…”

“…Only two studies have been conducted on daylily fragrance, both in China (Jiao et al, 2016;Lin et al, 2003). Lin et al (2003) subjected Hemerocallis flava flowers to simultaneous distillation-solvent extraction.…”

“…However, depending on the extraction process, the aroma of an essential oil can differ from the aroma experienced by a person smelling the flower from which the oil came (Tholl et al, 2006). Using headspace solid-phase microextraction and GC-MS, Jiao et al (2016) evaluated the volatile emissions of seven daylily species, one botanical variety, and 38 cultivars. They identified 37 volatiles, most of which were terpenoids.…”

For the past century, daylily (Hemerocallis) hybridization focused almost exclusively on enhancing the diversity of flower forms, colors, and color patterns. This focus on the visual characteristics of daylilies resulted in the development of thousands of hybrids that come in a fantastic array of colors and color patterns. However, these modern daylilies exhibit little to none of the floral fragrance possessed by some of the daylily progenitor species. Because little work has been done on daylily floral volatiles, the objective of this research was to evaluate the floral volatile profiles of a variety of daylily species and hybrids and assess the state of fragrance among modern hybrids. Using a field collection system and gas chromatography–mass spectrometry (GS-MS), this study evaluated the fragrance profiles of 147 daylily genotypes. Eighteen volatile organic compounds, primarily terpenoids, were identified and their variations among the genotypes were investigated. Results suggest that fragrance could be a trait pursued in a breeding program to enhance the sensory phenotypes of new daylily cultivars.

The volatile aroma released from agricultural products is closely related to the health status and quality of their growth, thus endowing the related detection with great significance. For example, the dynamic variation of the volatile chemical composition of a banana during the growth process can reflect its ripeness. Also important for quality monitoring and storage is to precisely and swiftly identify volatile compounds produced by mildew in rice and wheat. In this endeavor, the current detection technologies such as gas chromatography‐mass spectrometry method (GC‐MS) cannot meet the pressing needs of smart agriculture in terms of real‐time monitoring, cost‐effectiveness, sensitivity, and detection speed, thereby necessitating alternative strategies to simultaneously satisfy these requirements. Aiming to provide an overall development trend in this field, this paper summarizes the existing detection technologies including GC‐MS, E‐nose, and sensory analysis with their respective shortcomings and challenges, and then proposes the application prospects. This work can effectively enrich the reliable monitoring methods for volatile agricultural fragrance while promoting the long‐run development of smart agriculture.

Sleep disorders are widespread. Inhaled aromatherapy has shown advantages over medication in treating insomnia. Daylily (Hemerocallis fulva) has been found to positively affect sleep either by ingestion or inhalation, but there is a lack of research on the sleep aid effect of its inhalation route. At present, the floral scent characteristics of daylily are not obvious, and the extraction rate of essential oil is low. Based on the above problems, this study developed daylily essence which replicates the natural aroma of plants and investigated the effect of inhaling daylily essence aroma on sleep activity by using Pittsburgh Sleep Quality Index (PSQI) and electroencephalogram (EEG). According to PSQI results, inhaling the aroma of daylily essence improved participants' subjective sleep quality. The difference between men and women was statistically significant (p < .05). The slow‐wave sleep activity of EEG in the experimental group was significantly stronger than that in the control group (p < .01). In addition, the frontal and central regions were more responsive to aroma stimuli (p < .05). The results of this study show that the aroma of daylily can promote the subjective and objective sleep quality of healthy college students, and the use of fragrance intervention is a potential scheme to improve sleep quality and insomnia.
