www.nature.com/scientificreports OPEN Integrated transcriptomic and metabolomic data reveal the favonoid biosynthesis metabolic pathway in Perilla frutescens (L.) leaves Tao Jiang1,3, Kunyuan Guo2,3, Lingdi Liu1, Wei Tian1, Xiaoliang Xie1, Saiqun Wen1 & Chunxiu Wen1* Perilla frutescens (L.) is an important medicinal and edible plant in China with nutritional and medical uses. The extract from leaves of Perilla frutescens contains favonoids and volatile oils, which are mainly used in traditional Chinese medicine. In this study, we analyzed the transcriptomic and metabolomic data of the leaves of two Perilla frutescens varieties: JIZI 1 and JIZI 2. A total of 9277 diferentially expressed genes and 223 favonoid metabolites were identifed in these varieties. Chrysoeriol, apigenin, malvidin, cyanidin, kaempferol, and their derivatives were abundant in the leaves of Perilla frutescens, which were more than 70% of total favonoid contents. A total of 77 unigenes encoding 15 enzymes were identifed as candidate genes involved in favonoid biosynthesis in the leaves of Perilla frutescens. High expression of the CHS gene enhances the accumulation of favonoids in the leaves of Perilla frutescens. Our results provide valuable information on the favonoid metabolites and candidate genes involved in the favonoid biosynthesis pathways in the leaves of Perilla frutescens. Perilla frutescens (L.), which is a self-compatible annual herb, belongs to the family Lamiaceae. Tis species has been widely cultivated in China, Japan, and Korea for centuries. Perilla frutescens is an important medicinal and edible plant in China with medical and nutritional uses 1. Its leaves can be utilized as a transitional medicinal herb, as a vegetable, and as a spice, and its seeds can be processed into foods and nutritional edible oils 2. -

Miguel ABSTRACT Anthocyanins are polyphenols with known antioxidant activity which may be responsible for some biological activities including the prevention or lowering the risk of cardiovascular disease, diabetes, arthritis and cancer. Nevertheless such properties, their stability and bioavailability depend M. G. Miguel on their chemical structure. In the present work a brief review is made on chemical structures, Faculdade de Ciências e Tecnologia, bioavailability and antioxidant/anti -inflammatory of anthocyanins.

Bioengenharia, Universidade do Algarve, Campus de Gambelas, 8005- 139 Faro, PORTUGAL INTRODUCTION Anthocyanins are generally accepted as the largest and most important group of water- soluble pigments in nature (Harborne, 1998). They are responsible for the blue, purple, red and orange colors of many fruits and vegetables. The word anthocyanin derived from two Greek words: anthos, which means flowers, and kyanos, which means dark blue (Horbowicz et al., 2008). Major sources of anthocyanins are blueberries, cherries, raspberries, strawberries, black currants, purple grapes and red wine (Mazza, 2007). They belong to the family of compounds known as flavonoids, but they are distinguished from other flavonoids due to their capacity to form flavylium cations (Fig. 1) (Mazza, 2007). + O Fig 1. Flavylium cation. They occur principally as glycosides of their respective aglycone anthocyanidin- chromophores with the sugar moiety generally attached at the 3-position on the C-ring or the 5- position on the A-ring (Prior and Wu, 2006). -

Phenolic compounds are reactive metabolites in a wide range of plant-derived foods and mainly divided in four groups: phenolic acids, flavonoids, stilbenes and tannins. They work as terminators of free radicals and chelators of metal ions that are capable of catalyzing lipid oxidation. Therefore, this review examines the functional properties of phenolics. Index Terms—Health, functional, phenolic compounds. I. INTRODUCTION In recent years, fruits and vegetables receive considerable interest depending on type, number, and mode of action of the different components, so called as “phytochemicals”, for their presumed role in the prevention of various chronic diseases including cancers and cardiovascular diseases.

Anthocyanin and Glucosinolate Nutrients
ANTHOCYANIN AND GLUCOSINOLATE NUTRIENTS: AN EXPLORATION OF THE MOLECULAR BASIS AND IMPACT OF COLORFUL PHYTOCHEMICALS ON HUMAN HEALTH Abstract: Can eating food of an assortment of colors help one stay healthy? In this study, a randomized con- trolled trial helped evaluate the impact of a colorful diet on 8 healthy human adults (age 20-60) with similar demographic and dietary backgrounds. One of the daily meals of the volunteers was substituted with a hand- picked ration consisting of all colors of the rainbow in the form of a Rainbow Diet Pack (RDP). Fruits and vegeta- bles were chosen based on the exclusive molecular structure and chemical composition of the most prevalent phytonutrient(s) in each. RDP was administered daily to the intervention group (n=5) over a 10-wk interven- tion period. Weight loss, waist circumference, hand grip strength, and stress levels were measured. Analyses re- vealed that eating raspberries, oranges, carrots, broccoli, blueberries, and bananas balanced stress levels and led to weight loss, but did not impact hand-grip strength, demonstrating the healthy outcomes of a colorful diet..

Dietary Fiber Content and Associated Antioxidant Compounds in Roselle Flower (Hibiscus sabdariffa L.) Beverage † ‡ † SONIA G. SÁYAGO-AYERDI, SARA ARRANZ, JOSÉ SERRANO, AND ,† ISABEL GOÑI* Department of Nutrition, Faculty of Pharmacy, Universidad Complutense de Madrid, 28040 Madrid, Spain, and Department of Nutrition and Metabolism, Instituto del Frío, CSIC, Madrid 28040, Madrid Spain The beverage of Hibiscus sabdariffa flowers is widely consumed in Mexico. Polyphenols contained in plant foods are frequently associated with dietary fiber. The aim of this work is to quantify the dietary fiber, associated polyphenols, and antioxidant capacity of the Roselle flower and the beverage traditionally prepared from it and its contribution to the Mexican diet. Roselle flower contained dietary fiber as the largest component (33.9%) and was rich in phenolic compounds (6.13%). Soluble dietary fiber was 0.66 g/L in beverage, and 66% of total extractable polyphenols contained in Roselle flower passed to the beverage and showed an antioxidant capacity of 335 µmoL trolox equivalents/100 mL beverage measured by ABTS. These data suggest that Roselle flower beverage intake in the Mexican diet may contribute around 166 and 165 mg/per serving to the intake of dietary fiber and polyphenols, respectively. The health benefits from consumption of Hibiscus beverage could be of considerable benefit to the whole population.

In present study, we tested the influence of MEO and its most effective compounds α-humulene and trans-nerolidol on the cell adhesion, expression of adhesion molecules (ICAM-1; E-cadherin; β-catenin) and apoptotic molecules (NF-κB, caspases) in colorectal cancer cell line HT29. All parameters were followed up and compared in presence or absence of pro-inflammatory agent TNFα. The results showed that MEO was able to decrease adhesion of colon cancer HT29 cells to collagen. Furthermore MEO, α-humulene and trans-nerolidol significantly suppressed adhesion of TNFα-induced cells probably due to down-regulation of ICAM-1. -

Abstract Anthocyanins are naturally occurring compounds, member of the flavonoid groups of photochemical, involved in defense against the damaging effects of UV irradiation in plants and protect from many oxidants. The anthocyanins, group of pigments are relatively small and diverse flavonoid family in nature, and responsible for the attractive colors, red and purple to blue in many plants. Presence of pigments in flowers and fruits seems to provide attraction for pollination and aiding seed distribution, it also provides antiviral and antimicrobial activities, however their occurrence in the vacuoles remains ambiguous. -
Plant Gems from China©

So many new cultivars with Chinese genetics have been introduced in the landscape plant market. The Chinese love plants and particularly enjoy ten “traditionally famous flowers”: lotus (Nelumbo nucifera), sweet olive (Osmanthus frangrans), peony (Paeonia suffruticosa), azalea (Azalea spp.), chrysanthemum (Chrysanthemum spp.), Mei flower (Prunus mume), daffodil (Narcissus spp.), rose (Rosa spp.), camellia (Camellia spp.) and cymbidium (Cymbidium spp.). Public and university breeders have focused on these taxa. In addition, many species and cultivars commonly grown in China may be of interest to growers and landscape professionals in the U.S, which this manuscript will be focused on. PLANT SPECIES AND CULTIVARS Sweet olive (Osmanthus fragrans). There are mainly four types of sweet olives, Auranticus Group, Luteus Group, Albus Group, orange and Semperflorens Group. Ever-blooming sweet 1 2 olives have peak blooming in the fall like the others, and continue for about six months although not as profusely. Recently there are three variegated cultivars: ‘Yinbian Caiye’ with white leaf margins mature leaves and red/white/green on new growth, ‘Yintian Cai’ with red-margined maroon leaves maturing to white-margined green leaves, and ‘Pearl Color’ with pink new growth.
