  1. 6. The immunomodulatory properties of C-Med 100 an extract of the plant Uncaria tomentosa

    Författare :Christina Silver; Diabetes - immunovirologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; survival; proliferation; inhibition; NF-kB; Uncaria tomentosa; quinic acid;

    Sammanfattning : Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. LÄS MER

  3. 7. Pressurised Fluid Extraction of Bioactive Species in Tree Barks : Analysis using Hyphenated Electrochemical Mass Spectrometric Detection

    Sammanfattning : Analytical chemistry has developed throughout time to meet current needs. At present, the interest in biorefinery is growing, due to environmental awareness and the depletion of fossil resources. Biomass from agricultural and forestry industries has proven to be excellent raw material for different processes. LÄS MER

  4. 8. Enzymatic hydrolysis coupled to hot water extraction for determination of flavonoids in plants

    Författare :Sofia Lindahl; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extraction; flavonoids; quercetin; biocatalysis; beta-glucosidase; sustainable chemistry; hyphenation; molecularly imprinted polymers; onion;

    Sammanfattning : The word sustainability is more and more frequently used within the field of chemistry and in many other fields. Green or sustainable chemistry was introduced during the 90 ́s as a field of chemistry where the environmental and health impacts of processes and products are evaluated and improved. LÄS MER

  5. 9. Development of Methods for Analysis of Valuable Compounds in By-products from Agricultural and Forestry Industrial Sectors

    Författare :Mikael E Fridén; Per J R Sjöberg; Jonas Bergquist; Marja-Liisa Riekkola; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; industry by-products; flavonoids; triterpenes; mass spectrometry; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

    Sammanfattning : A growing interest in sustainable development has made efficient utilisation of starting materials and, if they occur, by-products become increasingly important. Vast amounts of by-products are generated by the forestry and food industry. LÄS MER

  7. 10. Hydrophobization of cellulose for bio-based materials

    Författare :Tianxiao Huang; Monica Ek; Merima Hasani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Betulin; Cellulose; Hydrophobicity; Mechanical properties; Polymer-matrix composites; Sustainability; Textile; Betulin; Cellulosa; Hydrofobicitet; Hållbarhet; Mekaniska egenskaper; Polymer-matriskompositer; Textil; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulosa, vilken är huvudkomponenten i växter förekommer rikligt i naturen, både på land och i havet. Cellulosabaserade material har i tusentals år använts av människan för dagliga förnödenheter som bränsle och konstruktionsmaterial. Cellulosa isolerades först av den franske forskaren Anselme Payen 1838. LÄS MER
