“…Based on the results of group G on U. decumbens germination, further potential allelochemicals isolation was carried out on it. The group G afforded 11 glycosylated avonols, being ve quercetin (1-5), two kaempferol (6-7) and four isorhamnetin derivatives (8-11), identi ed as: Quercetin-3-O-gentiobioside (1), Quercetin-3-O-robinobioside (2), Rutin (3), Hyperin (4), Isoquercitrin (5), Biorobin (6), Nicoti orin (7), Keioside (8), Narcissin (9), Cacticin (10) and Isorhamnetin-3-Oglucoside (11) (Novaes et al 2018).…”

Annona coriacea Mart. is a Brazilian native species whose phytotoxicity was described, although there is no data about the compounds responsible for it. The aim of this study was bioprospecting A. coriacea in relation to phytotoxicity on the elongation of wheat elongation coleoptiles and on germination and initial growth of standard target species (lettuce and tomato) and a weed (Urochloa decumbens (Stapf) R.D. Webster). Thus, the leaf ethanolic extract was subjected to chromatographic separation furnishing the isolation of 11 flavonols: 1 - Quercetin-3-O-gentiobioside, 2 - Quercetin-3-O-robinobioside, 3 - Rutin, 4 - Hyperin, 5 - Isoquercitrin, 6 - Biorobin, 7 - Nicotiflorin, 8 -Keioside, 9 - Narcissin, 10 - Cacticin and 11 - Isorhamnetin-3-O-glucoside. This is the first report of wheat coleoptile bioassay to all these compounds and it is also the first phytotoxicity results for 1, 2, 6, 8 and 10. Compounds 5, 7 and 11 showed elevated phytotoxicity in wheat coleoptiles bioassay (IC50 0.22 mM, r2 0.97; IC50 0.48 mM, r2 0.93; IC50 0.28 mM, r2 0.92, respectively). No correlation was found between the structure of the compounds and their activity. Compounds 5 and 11 were also tested on diaspores. Compound 11 significantly reduced the germination of U. decumbens in almost all concentrations, with values between 50% and 65%. The broad distinction concerning the complexity of the biological systems was suggested as an explanation for the distinct effects observed for coleoptile and germination and initial growth assays.

In 1789, the Annonaceae family was catalogued by de Jussieu. It encompasses tropical and subtropical plants which are widespread in distribution across various continents such as Asia, South and Central America, Australia and Africa. The genus of Annona is one of 120 genera of the Annonaceae family and contains more than 119 species of trees and shrubs. Most species are found in tropical America, where over 105 species have been identified. Due to its edible fruits and medicinal properties, Annona is the most studied genus of Annonaceae family. To date, only a limited number of these species have economic value, including A. squamosa L. (sugar apple), A. cherimola Mill. (Cherimoya), A. muricata L. (guanabana or soursop), A. atemoya Mabb. (atemoya), a hybrid between A. cherimola and A. squamosa, A. reticulata L. (custard apple), A. glabra L. (pond-apple) and A. macroprophyllata Donn. Sm. (ilama). Phytochemically, several classes of secondary metabolites, including acetogenins, essential oils, alkaloids, terpenoids and flavonoids. The pharmacological activities of Annona species leaves and seeds include antibacterial, anticancer, antidiabetic and anti-inflammatory properties.
