Abstract: Flavonoids belong to a class of plant secondary metabolites that have a polyphenol structure. Flavonoids show extensive biological activity, such as antioxidative, anti-inflammatory, anti-mutagenic, anti-cancer, and antibacterial properties, so they are widely used in the food, phar- maceutical, and nutraceutical industries. However, traditional sources of flavonoids are no longer sufficient to meet current demands. In recent years, with the clarification of the biosynthetic pathway of flavonoids and the development of synthetic biology, it has become possible to use synthetic metabolic engineering methods with microorganisms as hosts to produce flavonoids. This article mainly reviews the biosynthetic pathways of flavonoids and the development of microbial expression systems for the production of flavonoids in order to provide a useful reference for further research on synthetic metabolic engineering of flavonoids. Meanwhile, the application of co-culture systems in the biosynthesis of flavonoids is emphasized in this review.

A two-stage procedure for the extraction was adopted. The first extraction step was performed at ambient temperature (22C) and the second at elevated temperatures ranging 50-100C. The first step mainly gave a mixture of polysaccharides together with small amount of flavonoids. At the *Corresponding author.

The yield of solubilised carbohydrates steadily increased with a rise in the temperature, while the overall yield of flavonoids reached its optimum at 70C. An additional increase in the temperature resulted in a decrease in the yield. Model experiments using dihydroflavonols confirmed the occurrence of oxidative dehydrogenation and/or intramolecular rearrangement during the hydrothermal treatment at higher temperatures. The crude water extracts showed strong feeding deterrent activities against the subterranean termite, Coptotermes formosanus, in a choice paper disc assay.

Glycosylation usually improves flavonoid solubility but access to flavonoid glycosides is limited by their low production levels in plants. In this thesis work, the focus was placed on the development of new glucodiversification routes of natural flavonoids by taking advantage of protein engineering. Two biochemically and structurally characterized recombinant transglucosylases, the amylosucrase from Neisseria polysaccharea and the α-(1→2) branching sucrase, a truncated form of the dextransucrase from L. Mesenteroides NRRL B-1299, were selected to attempt glucosylation of different flavonoids, synthesize new α-glucoside derivatives with original patterns of glucosylation and hopefully improved their water-solubility.

Email: [email protected]; Chen Miao. Email: [email protected] Received: 08 June 2020; Accepted: 31 July 2020 Abstract: Sweet potato is a multifunctional root crop and a source of food with many essential nutrients and bioactive compounds. Variations in the flesh color of the diverse sweet potato varieties are attributed to the different phytochemicals and natural pigments they produce. Among them, carotenoids and anthocyanins are the main pigments known for their antioxidant properties which provide a host of health benefits, hence, regarded as a major component of the human diet. In this review, we provide an overview of the major pigments in sweet potato with much emphasis on their biosynthesis, functions, and regulatory control. More- over, current findings on the molecular mechanisms underlying the biosynthesis and accumulation of carotenoids and anthocyanins in sweet potato are discussed. Insights into the composition, biosynthesis, and regulatory control of these major pigments will further advance the biofortification of sweet potato and provide a reference for breeding carotenoid- and anthocyanin-rich varieties.

  • Evaluation of Anticancer Activities of Phenolic Compounds In
    EVALUATION OF ANTICANCER ACTIVITIES OF PHENOLIC COMPOUNDS IN BLUEBERRIES AND MUSCADINE GRAPES by WEIGUANG YI (Under the Direction of CASIMIR C. AKOH) ABSTRACT Research has shown that diets rich in phenolic compounds may be associated with lower risk of several chronic diseases including cancer. This study systematically evaluated the bioactivities of phenolic compounds in blueberries and muscadine grapes, and assessed their potential cell growth inhibition and apoptosis induction effects using two colon cancer cell lines (HT-29 and Caco-2), and one liver cancer cell line (HepG2). In addition, the absorption of blueberry anthocyanin extracts was evaluated using Caco-2 human intestinal cell monolayers. Polyphenols in three blueberry cultivars (Briteblue, Tifblue and Powderblue), and four cultivars of muscadine (Carlos, Ison, Noble, and Supreme) were extracted and freeze dried. The extracts were further separated into phenolic acids, tannins, flavonols, and anthocyanins using a HLB cartridge and LH20 column. In both blueberries and muscadine grapes, some individual phenolic acids and flavonoids were identified by HPLC with more than 90% purity in anthocyanin fractions. The dried extracts and fractions were added to the cell culture medium to test for cell growth inhibition and induction of apoptosis. Polyphenols from both blueberries and muscadine grapes had significant inhibitory effects on cancer cell growth. The phenolic acid fraction showed relatively lower bioactivities with 50% inhibition at 0.5-3 µg/mL. The intermediate bioactivities were observed in the flavonol and tannin fractions. The greatest inhibitory effect among all four fractions was from the anthocyanin fractions in the three cell lines. Cell growth was significantly inhibited more than 50% by the anthocyanin fractions at concentrations of 15-300 µg/mL.

Received September 6, 2010; accepted October 8, 2010 Two new flavonoid glycosides, (1, 2), and eleven known compounds, (3—13), were isolated from from a 70% EtOH extract of the leaves of Chromolaena odorata (Asteraceae). Their structures were elucidated by 1D and 2D NMR spectroscopic interpretation as well as by chemical studies. The newly isolated compounds were tested in vitro for their cytotoxic activities against the LLC and HL-60 cancer cell lines. Compound 1 showed cytotoxicity against LLC and HL-60 cancer cell lines with IC50 values of 28.2 and 11.6 mM, respectively.

    5 CHAPTER I INTRODUCTION GENERAL PATHWAYS OF MICROBIAL DEGRADATION OF AROMATIC COMPOUNDS A number of microorganisms can perform various types of reactions (Fonken and Johnson, 1972; Beukers et al., 1972) such as oxidation, reduction, hydrolysis, esterification, phosphorylation etc. These enzymatic reactions enable the microorganism to either synthesize or degrade complex organic compounds with ease. Such studies have become important from both fundamental and applied considerations. The microorganisms which are frequently used are fungi or bacteria. A great deal of work has been done on the microbiological transformation of steroids (Charney and Herzog, 1967) and a number of transformations have actually been exploited for commercial applications (Briggs and Brotherton, 1970). To cite an example, cortisone (l) an adrenocorticoid hormone which was effective against rheumatoid arthritis, a grave crippling disease was prepared by a sequence of chemical reaction from bile acids involving 32 steps (Peterson, 1963; Briggs and Brotherton, 1970). The formidable step was the introduction of an oxygen function (Carbonyl group) in the position 11 of the steroidal nucleus. With the combined chemical and microbial methods, the sequence of steps was reduced to only 12. Amongst steroids, the compounds studied are hormones of androstane Biit ocidt and pregnane series, estrogens, bile acids, cardenolides and bufadienolides. Studies have also been carried out on the microbial transformation of terpenes (Ciegler, 1969; Abbott and Cledhill, 1971), carbohydrates (Vezinae et al., 1968) and alkaloids (lizuka and Naito, 1967; Vining, 1969). Besides these compounds the microbial transforma­ tion studies were also reported on antibiotics (Sebek and Perlman, 1971; Sebek, 1974), herbicides (Kaufman and Kearney, 1976) and pesticides (Bollag, 1974) etc.
