“…For example, a mixture of solvents, dimethylacetamide (DMA)/lithium chloride (LiCl); dimethylformamide (DMF)/LiCl; 1,3‐dimethyl‐2‐imidazolinone (DMI)/LiCl; and dimethylsulfoxide (DMSO)/tetrabutylammonium fluoride (TBAF) are commonly used. A mixture of DMSO/(C 2 H 5 ) 3 N/SO 2 is a salt‐free solvent for cellulose 22–24 . Sometimes, it is necessary to heat the mixture to a high temperature (150–170°C) before the cellulose is dissolved in these solvents.…”

The present study provides an overview of scientific developments made in the last decade in the field of green adsorbents focusing on the modifications in cellulose and starch and their applications such as drug delivery, wastewater treatment, and ion exchange. For this purpose, an introduction to the various methods of modifying cellulose and starch is first given, and then the properties, application, and future priorities of green adsorbents are also discussed. Methods of modification of cellulose and starch under homogeneous and heterogeneous conditions using modifiers with different properties are also described. Various methods for modifying cellulose and starch and the use of the obtained green adsorbents are reviewed. A comparison of the sorption properties of green adsorbents based on cellulose and starch and other adsorbents used in industry has also been carried out. Future perspectives on green adsorbents based on cellulose and starch are as also highlighted.

“…The outermost stratum corneum of the skin is a barrier between the external environment and the internal environment, which can prevent water loss and foreign body invasion. Plant polysaccharides can form a film on the skin surface by absorbing moisture in the air and playing a moisturizing role (Li et al, 2022). Both Bletilla striata polysaccharides and Panax ginseng polysaccharides have excellent moisturereserving abilities (Thacker et al, 2020) and Tremella fuciformis polysaccharides can bind with the hydrogen in water molecules and are highly capable of locking and reserving water.…”

The purpose of this study was to prepare a multi-functional skin care product and apply more plant resources to the skin care industry. The crude polysaccharides from Bletilla striata, Panax ginseng, and Tremella fuciformis were extracted under different conditions based on the characteristics of the plants. The formula ratio of the compound Bletilla striata essence was optimized through an orthogonal experiment. The moisturizing, whitening, and antioxidant properties of the compound essence were evaluated by the weighing method, tyrosinase activity test, and DPPH free radical scavenging test, respectively. Finally, the improvement degree of skin condition was detected using a skin water and oil test instrument. The results showed that the polysaccharide contents of Bletilla striata, Panax ginseng, and Tremella fuciformis were 18.00±0.5, 41.70±0.7, and 20.25±0.6%, respectively. The optimal formula for the essence was: Bletilla striata extract 12 mg, Panax ginseng extract 8 mg, Tremella fuciformis extract 8 g, sodium hyaluronate 20 mg, and ultrapure water 50 mL. The moisture retention rate of the essence was 80.00±3.0%, the tyrosinase inhibition rate was 69.04±2.2%, and the DPPH radical scavenging rate was 71.03±2.5%. The skin water and oil test results showed that the compound essence can increase skin moisture and reduce skin oil. The product can reduce the content of pores, stains, wrinkles, roughness, acne and pigmentation, and has the potential to become a functional, natural and safe skin care product.

“…Moreover, they can be modified by various methods (e.g., acetylation, selenization, or phosphorylation) to improve their effectiveness. Proteins and polysaccharides have shown various promising biological effects in animal models, but there is a need for more clinical trials that would allow them to be introduced as functional foods, nutraceuticals, and pharmaceuticals [ 58 , 59 , 60 , 61 , 62 , 63 , 64 ].…”

Seeds contain a variety of phytochemicals that exhibit a wide range of biological activities. Plant-derived compounds are often investigated for their antioxidant, anti-inflammatory, immunomodulatory, hypoglycemic, anti-hypercholesterolemic, anti-hypertensive, anti-platelet, anti-apoptotic, anti-nociceptive, antibacterial, antiviral, anticancer, hepatoprotective, or neuroprotective properties. In this review, we have described the chemical content and biological activity of seeds from eight selected plant species—blackberry (Rubus fruticosus L.), black raspberry (Rubus coreanus Miq.), grape (Vitis vinifera L.), Moringa oleifera Lam., sea buckthorn (Hippophae rhamnoides L.), Gac (Momordica cochinchinensis Sprenger), hemp (Cannabis sativa L.), and sacha inchi (Plukenetia volubilis L). This review is based on studies identified in electronic databases, including PubMed, ScienceDirect, and SCOPUS. Numerous preclinical, and some clinical studies have found that extracts, fractions, oil, flour, proteins, polysaccharides, or purified chemical compounds isolated from the seeds of these plants display promising, health-promoting effects, and could be utilized in drug development, or to make nutraceuticals and functional foods. Despite that, many of these properties have been studied only in vitro, and it’s unsure if their effects would be relevant in vivo as well, so there is a need for more animal studies and clinical trials that would help determine if they could be applied in disease prevention or treatment.
