“…Important developmental plant processes, such as photosynthesis, protein synthesis, and carbohydrate, and lipid metabolism, are negatively affected when subjected to salt stress [31]. To deal with salt-induced ionic toxicity, osmotic stress, and secondary oxidative stress, salt-tolerant plant species often develop a variety of strategies to adapt to saline environments, such as detoxifying ROS and regulating ionic homeostasis [32].…”

Populus euphratica Oliv. is a model tree for studying abiotic stress, especially salt stress response. Salt stress is one of the most extensive abiotic stresses, which has an adverse effect on plant growth and development. Salicylic acid (SA) is an important signaling molecule that plays an important role in modulating the plant responses to abiotic stresses. To answer whether the endogenous SA can be induced by salt stress, and whether SA effectively alleviates the negative effects of salt on poplar growth is the main purpose of the study. To elucidate the effects of SA and salt stress on the growth of P. euphratica, we examined the morphological and physiological changes of P. euphratica under 300 mM NaCl after treatment with different concentrations of SA. A pretreatment of P. euphratica with 0.4 mM SA for 3 days effectively improved the growth status of plants under subsequent salt stress. These results indicate that appropriate concentrations of exogenous SA can effectively counteract the negative effect of salt stress on growth and development. Subsequently, transcripts involved in salt stress response via SA signaling were captured by RNA sequencing. The results indicated that numerous specific genes encoding mitogen-activated protein kinase, calcium-dependent protein kinase, and antioxidant enzymes were upregulated. Potassium transporters and Na+/H+ antiporters, which maintain K+/Na+ balance, were also upregulated after SA pretreatment. The transcriptome changes show that the ion transport and antioxidant enzymes were the early enhanced systems in response of P. euphratica to salt via SA, expanding our knowledge about SA function in salt stress defense in P. euphratica. This provides a solid foundation for future study of functional genes controlling effective components in metabolic pathways of trees.

“…Determination of liquid phase conditions: The three components F1, F2, F3 collected were scanned at full wavelength (200-800 nm) with the longest absorption wavelength at 210 nm. And it is known by TLC that component F1 is a highly polar substance and it is difficult to further separate it under the current liquid phase conditions [35]; F2, F3 are medium-polar substances, which can be effectively separated by a medium-polar eluent. The HPLC spectra of F1, F2 and F3 are shown in Fig.…”

Natural biologically active substances have received continuous attention for the potentially beneficial health properties against chronic diseases. In this study, bacteriostatic active substance from Camellia oleifera meal, which is a major byproduct of the Camellia oil processing industry, were extracted with continuous phase change extraction (CPCE) method and separated by HSCCC. Compared with traditional extraction methods, CPCE possessed higher extraction efficiency. Two main substances were separated and purified (above 90.0%). The structure of them were further identified by UV, LC-ESI-MS-MS, 1H-NMR, and 13C-NMR as flavonoids F2 kaempferol 3-O-[β-d-glucopyranosyl-(1 → 2)-α-l-rhamnopyranosyl-(1 → 6)]-β-dglucopyranoside and J2 kaempferol 3-O-[β-d-xylopyranosyl-(1 → 2)-α-l-rhamnopyranosyl-(1 → 6)]-β-d-glucopyranoside for the first time in C. Oleifera meal. The results of antibacterial activity measurement showed that both compounds have excellent antibacterial activity. And the antibacterial stability of F2 were finally confirmed: F2 showed broad spectrum antibacterial activity against Escherichia coli, Staphylococcus aureus, Salmonella enteriditis, Bacillus thuringiensis, Aspergillus niger and Rhizopus nigricans. Besides, F2 exhibited relatively high stable property even at high temperature, acid and metal ion solutions. The findings of this work suggest the possibility of employing C. oleifera meal as an attractive source of health-promoting compounds, and at the same time facilitate its high-value reuse and reduction of environmental burden.

“…Global consumers of saffron give high importance to saffron's quality because on one hand, the quality can affect consumers' health (Sereshti et al, 2018), and on the other hand, due to its high price, it is susceptible to fraudulent practices (Petrakis & Polissiou, 2017;Kiani et al, 2018).…”

Saffron, the stigmasof the plant Crocus sativusL.,hasattracted the worldwide interest for its specific organoleptic and pharmacological characteristics. Cultivation of saffron in Afghanistan began in recentyears and in very short time Afghan saffron hit higher record. Till now,there is no scientific study which has analyzed its characteristicsaccording to ISO methods. In this study, the maincomponentsof Afghan saffron have been described, and quality parameters along with its characteristics were analyzed accordingto ISO-3632-2test methods. The results of moisture analysis (5.12 to 5.74%)and determination of crocin (230.52-255.15) of Afghan saffron were at the range of standard as described for category I of saffron in ISO 3632-2 test methods. However, the results of some samples for safranal and picrocrocin (38.52-40.21 for safranal and 68.86-72.63 for picrocrocin) were higher than the range of category I of ISO 3632-2.
