“…These results showed that the rutin and kaempferol were identified in all Chamaerops extracts, a higher content was obtained in methanol extracts of leaflets (33 ± 2 µg g -1 ), water was extracted three times less rutin LW (10.9 ± 0.54 µg g -1 ). On a previous study rutin was identified from the C. humilis leaves (Hirai et al, 1986) and Phoenix dactylifera L. fruits (Hamad et al, 2015).…”

On this study, heated reflux extraction method has been used to identify the phenolic compounds from C. humilis var. argentea leaflets, rachis and fruits. Extractions were performed in both ultrapure water and 80% methanol solvents. The efficiency of procedures was determined in terms of the quality and quantity of phenolic acids and flavonoids identified. Chamaerops extracts have been characterized by high concentrations of phenolic compounds, which play a crucial role in protection against various diseases. LC-MS/MS was used to determine the chemical profile of various extracts obtained from Chamaerops. The results showed that the major components in leaflets and fruits extracts were quinic, malic and chlorogenic acids. On addition, nine minor acidic components were identified. Dn the other hand, rutin and hesperidin were found to be the major flavonoids. The methanol extract was shown as being the most efficient to identify phenolic compounds in C. humilis. Keywords: Chamaerops humilis L.; LC-ESO-MS/MS; phenolic compounds; chemical composition; extracts.Practical Application: Chamaerops humilis L. rich in flavonoids and phenolic acids was a great promising source of different bioactive components.

“…The existence of a genetic map (Mathew et al, 2014) makes it possible to choose useful genes, clone them and transform them into date palms to increase the yield or to improve agronomic qualities. Targeted genetic improvement programs will allow increasing the quantitative and specific secondary metabolites (Hamad et al, 2015) in planta. The in vitro culture of date palm is well establi-shed, and shoot tips are primarily used as explants for micropropagation.…”

Date palm (Phoenix dactylifera L.) is the source of fruit and palm oil, which is broadly used in the food industry.The regeneration of recalcitrant date palm genotypes through somatic embryogenesis or organogenesis is difficult to achieve. Micropropagation, however, provides a way to obtain a sufficient number of true-to-type elite, healthy (disease-free) and vigorous plants to satisfy local and international markets. This mini-review highlights some of the main achievements in the tissue culture of date palm. In particular, explant selection and disinfection, shoot induction, multiplication and elongation, root induction and acclimatization are highlighted. In addition to using the in vitro tissue culture as the basis for an in vitro gene banking, a mid-term low-temperature storage of germplasm is possible by careful selection of the osmotic agent. A long-term storage of date palm using cryopreservation, with or without synthetic seeds is also possible. Molecular markers, as well as sex-specific markers, have been useful to discriminate germplasms and to identify somaclonal variants derived from tissue cultures. The genetic transformation of date palm can be achieved by either particle bombardment or Agrobacterium -based protocols. Thus, biotechnology is an important element of date palm germplasm development and its sustainable improvement.

“…Metabolic profiling of different varieties of date palm revealed varying level of chemical ingredients such as phenolics, amino acids and minerals. Efficacies of various biological activities have also been reported to be dependent upon the type of cultivars and on the ripening stage of fruits (Amira et al 2012;Hamad et al 2015). Al-Dous et al (2011) identified 32 SNP (in total 3.5 million) in the genomes of the three date palm varieties.…”

Medicinal plant research is growing significantly in faith to discover new and more biologically compatible phytomedicines. Deposition of huge genome/trancriptome sequence data assisted by NGS technologies has revealed the new possibilities for producing upgraded bioactive molecules in medicinal plants. Growing interest of investors and consumers in the herbal drugs raises the need for extensive research to open the facts and details of every inch of life canvas of medicinal plants to produce improved quality of phytomedicines. As in agriculture crops, knowledge emergence from medicinal plant's genome/transcriptome, can be used to assure their amended quality and these improved varieties are then transported to the fields for cultivation. Genome studies generate huge sequence data which can be exploited further for obtaining information regarding genes/gene clusters involved in biosynthesis as well as regulation. This can be achieved rapidly at a very large scale with NGS platforms. Identification of new RNA molecules has become possible, which can lead to the discovery of novel compounds. Sequence information can be combined with advanced phytochemical and bioinformatics tools to discover functional herbal drugs. Qualitative and quantitative analysis of small RNA species put a light on the regulatory aspect of biosynthetic pathways for phytomedicines. Inter or intra genomic as well as transcriptomic interactive processes for biosynthetic pathways can be elucidated in depth. Quality management of herbal material will also become rapid and high throughput. Enrichment of sequence information will be used to engineer the plants to get more efficient phytopharmaceuticals. The present review comprises of role of NGS technologies to boost genomic studies of pharmaceutically important plants and further, applications of sequence information aiming to produce enriched phytomedicines. Emerging knowledge from the medicinal plants genome/transcriptome can give birth to deep understanding of the processes responsible for biosynthesis of medicinally important compounds.
