Actually by-products from lettuce and cabbage have not been properly used despite the fact that they are rich in bioactive compounds as lutein. It is known that lutein plays an important role in the prevention of degenerative diseases. Lutein, is recommended as a health supplement for the prevention of cancer and diseases related to retinal degeneration or to ameliorate the effects of degenerative diseases such as age-related macular degeneration. The aim of this work was to extract lutein from a mix of dried cabbage and lettuce using supercritical fluid extraction with CO 2 as solvent (SFE-CO 2 ), under different combinations of pressure and temperature in order to determining the lutein yield, total yield and antioxidant capacity. Also the extraction kinetic of lutein from cabbage and lettuce is shown in this work. The best lutein yield was obtained at 350 bar and 65°C, while the highest antioxidant capacity was at 400 bar and 85°C.

“…The flowers of daylily have been widely consumed as cuisine food for thousands of years. The extracts from daylily flowers have been shown to inhibit cell proliferation, induce cancer cells to undergo differentiation (Cichewicz et al ., ) and exhibit strong antioxidant activity owing to its bioactive components (Hsu et al ., ; Lin et al ., ). However, perishable characteristic of the daylily and its huge output in booming season cry for the preservation processing.…”

Drying kinetics of fresh daylily flower buds (Hemerocallis Citrine Baroni cv. Mengzihua) in a microwave oven at 60, 120, 180 and 240 W, respectively, were investigated. The results indicated that, drying rate increased at the initial time (a warm-up period) and then decreased at the end time (a falling rate period) after reaching a plateau (a constant rate period). A third-order polynomial model could well describe the relationships between effective diffusivity and moisture content, and the model's coefficients correlated linearly with microwave power level. A logistic model could well present the relationships between activation energy and moisture content. The curves of energy consumption vs. microwave power level indicated that in the initial phase of drying, the energy utilisation efficiency was almost the same at different microwave output power levels; however, at the end phase of drying, drying at lower microwave levels was worse in energy utilisation.

“…The medicinal value of Hemerocallis species has received more attention in recent years. The flower buds seem to be enriched with antioxidants, such as stelladerol and caffeoylquinic acid derivatives Hsu et al, 2011;Lin et al, 2011;Jiao et al, 2016). These secondary metabolites are used to treat anxiety and swelling (Uezu, 1998;Gu et al, 2012;Yi et al, 2012;Du et al, 2014;Liu et al, 2014), and for other applications in modern medicine and biology (Venugopalan and Srivastava, 2015).…”

Hemerocallis spp. commonly known as daylilies and night lilies, are among the most popular ornamental crops worldwide. In Eastern Asia, H. citrina is also widely cultivated as both a vegetable crop and for medicinal use. However, limited genetic and genomic resources are available in Hemerocallis. Knowledge on the genetic diversity and population structure of this species-rich genus is very limited. In this study, we reported transcriptome sequencing of H. citrina cv. 'Datonghuanghua' which is a popular, highyielding variety in China. We mined the transcriptome data, identified and characterized the microsatellite or simple sequence repeat (SSR) sequences in the expressed genome. From ∼14.15 Gbp clean reads, we assembled 92,107 unigenes, of which 41,796 were annotated for possible functions. From 41,796 unigenes, we identified and characterized 3,430 SSRs with varying motifs. Forty-three SSRs were used to fingerprint 155 Hemerocallis accessions. Clustering and population structure analyses with the genotypic data among the 155 accessions reveal broader genetic variation of daylilies than the night lily accessions which form a subgroup in the phylogenetic tree. The night lily group included accessions from H. citrina, H. lilioasphodelus, and H. minor, the majority of which bloom in the evening/night, whereas the ∼100 daylily accessions bloomed in the early morning suggesting flowering time may be a major force in the selection of night lily. The utility of these SSRs was further exemplified in association analysis of blooming time among these accessions. Twelve SSRs were found to have significant associations with this horticulturally important trait.
