“…Besides, palmitic and linoleic acids, the main fatty acids in the four flowers species studied, can be added to coatings used by the food industry, as well as to cosmetics and some industrial polymers (Rajput, Hundiwale, Mahulikar, & Gite, 2014). Centaurea is rich in fiber that can have several applications, such as dietary fibers, and in biodegradable films, natural fiber composites, biopolymers, and pharmaceuticals (Ramawat & Ahuja, 2016). However, in the present study, other phytochemicals, such as flavonoids, anthocyanins, and tannins, also present in edible flowers (Loizzo et al, 2016;Rachkeeree et al, 2018;Navarro-González et al, 2015), were not evaluated.…”

The present study aimed to evaluate the nutritional and bioactive potential of four edible flowers (borage, centaurea, camellia, and pansies). Significant differences were observed among the four. Water was the main constituent (> 76%, fresh weight-fw). Linoleic and palmitic acids were the major fatty acids found in borage and red and yellow pansies, while in camellia it was the arachidic acid. In white pansies, behenic and arachidic acids were predominant. Concerning vitamin E, α-tocopherol was the major vitamer. Carotenoids values varied between 5.8 and 181.4 mg β-carotene/100 g dry weight (dw) in centaurea and borage, respectively, being particularly rich in lutein. Malic acid was the major organic acid, except in centaurea, where succinic acid was predominant. Fructose, glucose and sucrose were detected in all flowers. These results can contribute to the knowledge of these edible flowers and consequently increase their popularity among consumers and in the food industry.

“…Some plants have been used for fibers since Neolithic times [2], while others were brought to attention only lately [3,4]. Fibers can be obtained from various organs of certain plants depending on the species, such as stem, bark, leaf, root, fruit or seed [4][5][6]. Today, plant-based natural fibers are considered highly convenient bio-degradable materials due to their low cost, recycling possibilities and lack of polluting emissions into the environment [7,8].…”

Comparative FT-IR Prospecting for Cellulose in Stems of Some Fiber Plants: Flax, Velvet Leaf, Hemp and Jute

Plant fibers are sustainable sources of materials for many industries, and can be obtained from a variety of plants. Cellulose is the main constituent of plant-based fibers, and its properties give the characteristics of the fibers obtained. Detailed characterization of cellulosic fibers is often performed after lengthy extraction procedures, while fast screening might bring the benefit of quick qualitative assessment of unprocessed stems. The aim of this research was to define some marker spectral regions that could serve for fast, preliminary qualitative characterization of unprocessed stems from some textile plants through a practical and minimally invasive method without lengthy extraction procedures. This could serve as a screening method for sorting raw materials by providing an accurate overall fingerprint of chemical composition. For this purpose, we conducted comparative Fourier Transform Infrared Spectroscopy (FT-IR) prospecting for quality markers in stems of flax (Linum usitatissimum L.), velvet leaf (Abutilon theophrasti Medik.), hemp (Cannabis sativa L.) and jute (Corchorus olitorius L.). Analysis confirmed the presence of major components in the stems of the studied plants. Fingerprint regions for cellulose signals were attributed to bands at 1420–1428 cm−1 assigned to the crystalline region and 896–898 cm−1 assigned to the amorphous region of cellulose. The optimization of characterization methods for raw materials is important and can find immediate practical applications.

“…Kenaf fiber is characterized chemically by cellulose (58%-63%) and lignin (12%-14%), which are also traits that are important for improving fiber quality [30][31][32]. However, cellulose content in kenaf is relatively low compared with other fiber crops such as flax (78%-80%), hemp (75%-80%), jute (60%-65%), and ramie (70%-75%) [33]. Cellulose is a polymer of β-(1→4)-glucose residues that form a linear unbranched chain.…”

Kenaf is a source of fiber and a bioenergy crop that is considered to be a third world crop. Recently, a new kenaf cultivar, "Jangdae," was developed by gamma irradiation. It exhibited distinguishable characteristics such as higher biomass, higher seed yield, and earlier flowering than the wild type. We sequenced and analyzed the transcriptome of apical leaf and stem using Pacific Biosciences single-molecule long-read isoform sequencing platform. De novo assembly yielded 26,822 full-length transcripts with a total length of 59 Mbp. Sequence similarity against protein sequence allowed the functional annotation of 11,370 unigenes. Among them, 10,100 unigenes were assigned gene ontology terms, the majority of which were associated with the metabolic and cellular process. The Kyoto encyclopedia of genes and genomes (KEGG) analysis mapped 8875 of the annotated unigenes to 149 metabolic pathways. We also identified the majority of putative genes involved in cellulose and lignin-biosynthesis. We further evaluated the expression pattern in eight gene families involved in lignin-biosynthesis at different growth stages. In this study, appropriate biotechnological approaches using the information obtained for these putative genes will help to modify the desirable content traits in mutants. The transcriptome data can be used as a reference dataset and provide a resource for molecular genetic studies in kenaf.
