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.

“…Using traditional UV spectroscopy techniques, Novaes et al identified in A. coriacea leaves the presence of the quercetin, found in a more significant proportion, followed by kaempferol and isorhamnetin [ 72 ]. In 2019, Novaes and collaborators identified the presence of eleven flavonoids in the leaves of marolinho ( A. coriacea ), emphasizing quercetin-3- O -gentiobioside and quercetin-3- O -robinobioside in a similar way to the previous study, and also for rutin [ 62 ].…”

The Annonaceae family is widely distributed in subtropical and tropical regions. Several species of this family are known for their pharmacological and beneficial properties to human health, mainly attributed to flavonoids. The objective of this work was to carry out an integrative review in order to identify the main flavonoids found in some plant parts belonging to the Annona genus: araticum tree (Annona crassiflora Mart.), graviola tree (Annona muricata), atemoya tree (Annona cherimolia Mill × Annona squamosa L.), pinha tree (Annona squamosa), bananinha tree (Annona leptopetala), and marolinho tree (Annona coriacea). Only articles published between the years 2016 to 2021 that answered the guiding question were considered, in order to obtain recent data. Then, search strategies were designated for each database used: Science Direct, CAPES Periodicals, and Scielo. Most of the studies retrieved from the databases are related to fruits. The results showed that the number of flavonoids identified varies according to the analytical methodology used to identify and quantify the compounds. Quercetin was the most commonly found compound in all fruits of the Annona genus studied, and epicatechin, rutin, and kaempferol were also found to a lesser extent. The presence of these compounds in Annona makes the fruit promising, with potential applicability in the pharmaceutical and food industry.

“…is a species to Brazilian cerrado, [1] popularly known as marolo, araticum‐do‐campo or araticum. Chemical studies with this species have resulted in the discovery of phenolic acids and flavonoids, [2] diterpenoids, [3] alkaloids [4] and acetogenins [4,5] . Acetogenins are natural products mostly found in Annonaceae plants.…”

Our search for candidates for photosynthesis inhibitors is allowing us to report the effect of two acetogenins identified in Annona coriacea Mart. leaves, ACGÀ A and ACGÀ B, a non-adjacent bis-THF and a mono-THF types, respectively. This is an important class of natural products which presents biological properties such as anticancer, neurotoxic, larvicidal and insecticidal. However, this is only the second report associated to its herbicidal activity. Their mechanisms of action on the light reactions of the photosynthesis were elucidated by polarographic techniques. Compounds inhibited the noncyclic electron transport on basal, phosphorylating, and uncoupled conditions from H 2 O to methyl viologen (MV); therefore, they act as Hill reaction inhibitors. Studies on fluorescence of chlorophyll a (ChL a) indicated that they inhibited the acceptor side of PSII between P680 and PQ-pool, exactly as the commercial herbicide DCMU does.
