    The Vegetation ofRobinson Crusoe Island (Isla Masatierra), Juan Fernandez Archipelago, Chile1 Josef Greimler,2,3 Patricio Lopez 5., 4 Tod F. Stuessy, 2and Thomas Dirnbiick5 Abstract: Robinson Crusoe Island of the Juan Fernandez Archipelago, as is the case with many oceanic islands, has experienced strong human disturbances through exploitation ofresources and introduction of alien biota. To understand these impacts and for purposes of diversity and resource management, an accu­ rate assessment of the composition and structure of plant communities was made. We analyzed the vegetation with 106 releves (vegetation records) and subsequent Twinspan ordination and produced a detailed colored map at 1: 30,000. The resultant map units are (1) endemic upper montane forest, (2) endemic lower montane forest, (3) Ugni molinae shrubland, (4) Rubus ulmifolius­ Aristotelia chilensis shrubland, (5) fern assemblages, (6) Libertia chilensis assem­ blage, (7) Acaena argentea assemblage, (8) native grassland, (9) weed assemblages, (10) tall ruderals, and (11) cultivated Eucalyptus, Cupressus, and Pinus. Mosaic patterns consisting of several communities are recognized as mixed units: (12) combined upper and lower montane endemic forest with aliens, (13) scattered native vegetation among rocks at higher elevations, (14) scattered grassland and weeds among rocks at lower elevations, and (15) grassland with Acaena argentea. Two categories are included that are not vegetation units: (16) rocks and eroded areas, and (17) settlement and airfield. Endemic forests at lower elevations and in drier zones of the island are under strong pressure from three woody species, Aristotelia chilensis, Rubus ulmifolius, and Ugni molinae. The latter invades native forests by ascending dry slopes and ridges.

Stuntz] was determined by HPLC with photodiode array and MS detection. Eight pigments corresponding to the 3-glucosides, 3,5-diglucosides, 3-sambubiosides and 3- sambubioside-5-glucosides of delphinidin and cyanidin were identified, the principal anthocyanin being delphinidin 3- sambubioside-5-glucoside (34% of total anthocyanins). The average total anthocyanin content was 137.6 ± 0.4 mg/100 g of fresh fruit (211.9 ± 0.6 mg/100 g of dry fruit). The relative high anthocyanin content and the important presence of polar polyglycosylated derivatives makes the fruits of A. chilensis an interesting source of anthocyanin extracts for food and phar- maceutical uses.

  • Aristotelia Chilensis
    Vergara et al. Nutrition Journal (2015) 14:27 DOI 10.1186/s12937-015-0008-1 SHORT REPORT Open Access The intake of maqui (Aristotelia chilensis) berry extract normalizes H2O2 and IL-6 concentrations in exhaled breath condensate from healthy smokers - an explorative study Daniela Vergara, Daniela Ávila, Elizabeth Escobar, Catalina Carrasco-Pozo, Andrés Sánchez and Martin Gotteland* Abstract Background: Respiratory diseases are associated with pulmonary oxidative stress and inflammatory processes. Though studies in animal models suggest that dietary polyphenols improve lung injury, no intervention studies were carried out in humans. The aim of this study was to determine whether the intake of an anthocyanin-rich maqui extract improved H2O2 and IL-6 concentrations in exhaled breath condensates (EBCs) from asymptomatic smokers. Findings: 15 asymptomatic smokers with mild cigarette smoking (3 pack-year [2.4 - 7.7]) (mean [CI95%]) were recruited in this exploratory longitudinal study. They ingested 2 g of maqui extract (polyphenol content = 5.18 ± 2.00 g GAE/100 g; FRAP value = 27.1 ± 2.0 mmol Fe++/100 g), twice daily for two weeks. EBCs were collected before and after treatment and the changes in H2O2 and IL-6 concentrations were determined by fluorimetry and Elisa, respectively. The EBC contents of H2O2 and IL-6 H2O2 before and after treatment in smokers were also compared with those determined in single EBC samples from 8 healthy non-smokers subjects. At baseline, the H2O2 concentrations were higher and those of IL-6 lower in the smokers than in the non-smokers. Maqui extract significantly decreased H2O2 (p < 0.0002) and increased IL-6 (p < 0.004) in the EBC from smokers.

Angiosperm ovules are diverse in their position in the ovary, nucellus thickness, number and thickness of integuments, degree and direction of curvature, and histological differentiations. There is a large body of literature on this diversity, and various views on its evolution have been proposed over the course of time. Most recently evo–devo studies have been concentrated on molecular developmental genetics in ovules of model plants. † Scope The present review provides a synthetic treatment of several aspects of the sporophytic part of ovule http://aob.oxfordjournals.org/ diversity, development and evolution, based on extensive research on the vast original literature and on experi- ence from my own comparative studies in a broad range of angiosperm clades. † Conclusions In angiosperms the presence of an outer integument appears to be instrumental for ovule curvature, as indicated from studies on ovule diversity through the major clades of angiosperms, molecular developmental genetics in model species, abnormal ovules in a broad range of angiosperms, and comparison with gymnosperms with curved ovules.

Abstract: A. chilensis (Elaeocarpaceae) is commonly known as maqui, a species widely distributed in Chile. The plant participates in the structure of the Chilean temperate rainforest, currently being found mainly as fragmented forest. Maqui has been listed as the plant with the highest content of phenols when compared with other berries. Multiplication by both, seeds and vegetative has been obtained, opening the possibility to cultivate the plant. Leaves of maqui have been traditionally used in the native herbal medicine to treat diverse ailments. Studies indicate the presence of indolic alkaloids, flavonoids, cyaniding glucosides, delfidine, malvidine, petunidine, cumarines and triterpenes. Recent studies support therapeutic properties of maqui leaves, concluding that extracts obtained with polar solvents showed stabilizing capacity of free radicals and antioxidant capacity of plasma in humans.

  • POLYPHENOL CONTENT and ANTIOXIDANT ACTIVITY of MAQUI (Aristotelia Chilensis [MOLINA] STUNTZ) DURING FRUIT DEVELOPMENT and MATURATION in CENTRAL CHILE
    SCIENTIFIC NOTE POLYPHENOL CONTENT AND ANTIOXIDANT ACTIVITY OF MAQUI (Aristotelia chilensis [MOLINA] STUNTZ) DURING FRUIT DEVELOPMENT AND MATURATION IN CENTRAL CHILE Carolina Fredes1*, Gloria Montenegro1, Juan Pablo Zoffoli1, Miguel Gómez1, and Paz Robert2 Maqui (Aristotelia chilensis [Molina] Stuntz, Elaeocarpaceae) is a Chilean native species which produces small berries that are mainly collected from the wild. The health benefits of maqui fruit are attributed to their high polyphenol content as well as their wide variety of anthocyanins and flavonols. One of the main factors that affect the polyphenol content in fruit is the maturity stage at harvest. The objective of this study was to determine total phenol and total anthocyanin content and antioxidant activity (by ferric reducing ability of plasma [FRAP] assay) of maqui fruits harvested at different fruit maturity stages from two wild populations located in Central Chile. Each maturity stage was determined by days from fruit set, berry size, and soluble solids. Total phenol content declined while total anthocyanin content increased from the green to light red stage. Nevertheless, both total phenol and anthocyanin content increased from the light red to dark purple stage. The highest anthocyanin content and antioxidant activity was found in the late maturity stage (dark purple). The results show that ripening in maqui fruit can be expected with 1100 growing degree-days (91 d after fruit set) in Central Chile. At this moment of harvest, fruits with 18-19 °Brix have the highest anthocyanin content and antioxidant activity (FRAP). This study constitutes the first advances in the understanding of maqui fruit ripening and corresponding antioxidant activity.

The sustainable way to produce raw material on a large scale would be species specific management of the wild resources that guarantees conserva- tion of biodiversity, or bringing the species under cultivation. A checklist proposed by WHO, UICN and WWF (1993) indicates that domestication of any medicinal plant concerns plant selection and breeding, studies about propagation, cultivation techniques, plant protection, time of harvest, among others. The different domestication steps are illustrated for the Chilean maqui (Aristotelia chilensis), a wild tree whose fruits are demanded in increasing volumes by the international market because of its high antioxidant capacity. High yielding plants with good fruit quality have been selected from wild populations and accessions have been cultivated under different environ- mental conditions to select the most suitable genotypes for the establishment of commercial orchards.
