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.

Endress* Institute of Systematic Botany, University of Zurich, Zollikerstrasse 107, 8008 Zurich, Switzerland * E-mail [email protected] Received: 2 March 2011 Returned for revision: 29 March 2011 Accepted: 11 April 2011 Published electronically: 23 May 2011 † Background Ovules as developmental precursors of seeds are organs of central importance in angiosperm Downloaded from flowers and can be traced back in evolution to the earliest seed plants. 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.

ISSN 2153 733X DITTRICHIA GRAVEOLENS (ASTERACEAE) IS NATURALIZED AND INVASIVE IN NEW YORK STATE DANIEL ATHA Center for Conservation Strategy New York Botanical Garden Bronx, New York 10458 [email protected] ZIHAO WANG 30 Van Sicklen Street Brooklyn, New York 11223 [email protected] CATHERINE BARRON P.O. Box 100134 Staten Island, New York 10310 [email protected] HEATHER LILJENGREN Greenbelt Native Plant Center NYC Parks Staten Island, New York 10314 [email protected] ABSTRACT Dittrichia graveolens (Asteraceae) is known from five populations widely scattered on Staten Island, Richmond Co, New York, indicating that the species is naturalized and well-established in New York City and New York state. Dittrichia graveolens (L.) Greuter (stinkwort) was first collected in New York State in 1949 by Harold Moldenke and Joe Monachino in Bronx County ( Moldenke 20555 and Monachino 529 ). Monachino collected the species again in Brooklyn, Kings Co., in October 1959 ( Monachino 632 ). The species was not collected or documented again in New York state until the present work and was thought to be historical (Weldy et al. 2019; Atha & Boom 2018; USDA NRCS 2018; Werier 2017).
