Texte intégralLignin is the most abundant component of wood after cellulose and is separated from whilepaper production. Within this lingo-cellulosic biomass, in case of graminous, ferulic acid is a crosslinkingagent binding lignin to polysaccharide fibers to increase its mechanical properties. If lignin iscomplex and poorly degradable, ferulic acid, as it is present free, is extractible in alkali media frommany resources (beetroot pulp, wheat, corn, rice...).By its aromatic nature, this p-hydroxycinnamic acid seems interesting to prepare new polymersincorporating biobased aromatic units. Indeed, if biobased polymers are more and more nowadays,today biobased aromatic units are still missing.In this aim, into the APSYNTH team, we developed a new class of biobased bisphenols obtainedthrough enzymatic catalysis. These bisphenols were then implicated in different strategies to developnew copolyesters, polyurethanes and polyphenolic oligomers. This work describes the synthesis andcharacterization of this new bisphenols derived from ferulic acid, as well as the resulting polymers

Oxidative stress contributes to skin aging and can adversely affect skin health, which means supplement antioxidants active may support skin health, and suppress the production that the epidermis bacterium can reduce the whelk and comedo. Our objective supplemented carbon source: glucose, glycerol, trehalose, maltose and citric acid; or extra 2% nitrogen source: KNO3 and MSG fermentation 5, 10 and 15 days to obtain aqueous extract and methanolic extracts of Monascus rice with different oligomeric tea extracts to experimental valuate the antioxidant properties, antibacterial activity and protective effects on UV-induced damage in HaCaT keratinocytes effect. Supplement KNO3 and MSG fermentation extracts have higher reducing powers, DPPH radical scavenging ability, inhibition of tyrosinase activity and NO-suppressing activity, and furthermore them has higher phenolic and kojic acid yield. Both extracts were active against S. aurous. Suppress MSG ferment 10 days water exctracts protect UV-induced damage in HaCaT keratinocytes, and protect nitric oxide induced damage. Oligomeric tea fraction to medium molecular weight tea (MMT), high molecular weight tea (HMT), and unfractionated total molecular weight tea (TMT). The results showed that HMT has well yield at phenolic and kojic acid. Our data showed that MMT has the highest antioxidant activity and higher antibacterial activity than Monascus rice extracts. Three kinds of tea extracts have the bioactivity on against S. aurous, but it’s no different of statistics. The results showed MMT has the best protective effects on UV-induced damage in HaCaT keratinocytes. And the various extracts from tea can increased cell viability at the concentration of 100 μg/ml in HaCaT cell line. It’s no apparent different of statistics. The research proves that Monascus has phenolic acid, anti-oxidatives and antibiotic ability. And it’s can protect cell against UV and free radical damage. Supplement KNO3 and MSG fermentation extracts can increase antioxidant activity. High polyphenolic tea extract showed higher activity than Monasucs rice extract. The medium oligomeric polyphenolic tea has more excellent effects than high oligomeric polyphenolic tea.

Previous research is proved that absorption of consumption polyphenolic-rich subsidiaries can decrease the incidence of diseases, such as cancer and coronary artery disease. The aim of this thesis was to investigate the influence of oligomeric polyphenolics from tea and longan flower on the growth of human colorectal carcinoma cell lines(SW480 and Colo 320DM). The tea was fractionated to oligomer-rich and polymer-rich extract by membrane separation. Cell cycle analysis, mitochondria membrane potential, membrane alteration and protein expression were determined in this thesis. All the extracts contained polyphenolic compounds and showed prominent antioxidant activity. The results showed that oligomeric polyphenolics, especially longan flower, systemically inhibited the proliferation of SW480 and Colo 320DM in a dose dependent manner. Longan flower tea extract showed strong S phase blocking activity at the concentration of 200 μg/mL to 400 μg/mL on these two cell lines. Protein expression results showed the close relationship between S phase arrest and cell cycle regulators cyclin A and cyclin E. The mitochondria membrane potential of treated cells was also loss. Longan flower extract increased apoptoic cell death at the concentration of 400 μg/mL on SW480 and 200 μg/mL on Colo 320DM. According to these results revealed that oligomeric polyphenol have anti-proliferative, S phase blocking, mitochondria membrane potential loss and apoptosis inducing activity. These results provide a further evaluation for its application as a nature cancer chemopreventive agent and health food.
