“…On this basis, studies have focused on evaluating plant biodiversity as a compound reservoir for therapeutic purposes, in addition to elucidating medicinal activities attributed by popular tradition [ 12 , 15 ]. In this context, Turnera subulata (Passifloraceae family) is a species with wide distribution in tropical and subtropical regions [ 16 , 17 ], used in folk medicine due to its pharmacological properties, such as anti-inflammatory, hypoglycemic, antifungal, and antioxidant activity [ 16 , 18 , 19 , 20 , 21 ]. Phytochemical studies with species of the Turnera genus have revealed the presence of flavanols, alkaloids, tannins, cyanogenic glycosides, fatty acids, triterpenoids, and various phenolic compounds related to their bioactivities [ 16 , 22 ].…”

Chemical Characterization of Flowers and Leaf Extracts Obtained from Turnera subulata and Their Immunomodulatory Effect on LPS-Activated RAW 264.7 Macrophages

The anti-inflammatory properties of Turnera subulata have been evaluated as an alternative drug approach to treating several inflammatory processes. Accordingly, in this study, aqueous and hydroalcoholic extracts of T. subulata flowers and leaves were analyzed regarding their phytocomposition by ultrafast liquid chromatography coupled to mass spectrometry, and their anti-inflammatory properties were assessed by an in vitro inflammation model, using LPS-stimulated RAW-264.7 macrophages. The phytochemical profile indicated vitexin-2-O-rhamnoside as an important constituent in both extracts, while methoxyisoflavones, some bulky amino acids (e.g., tryptophan, tyrosine, phenylalanine), pheophorbides, and octadecatrienoic, stearidonic, and ferulic acids were detected in hydroalcoholic extracts. The extracts displayed the ability to modulate the in vitro inflammatory response by altering the secretion of proinflammatory (TNF-α, IL-1β, and IL-6) and anti-inflammatory (IL-10) cytokines and inhibiting the PGE-2 and NO production. Overall, for the first time, putative compounds from T. subulata flowers and leaves were characterized, which can modulate the inflammatory process. Therefore, the data highlight this plant as an option to obtain extracts for phytotherapic formulations to treat and/or prevent chronic diseases.

“…In addition, it is worth noting that the number of species indicated for the flora of Ceará (BFG 2018; Flora do Brasil 2020 under construction) is incomplete. Recent studies linked to the "Flora of Ceará Project: knowing to conserve" have shown how much the floristic diversity of that state is underestimated, confirmed with quotes from new records (Capistrano & Loiola 2015;Tabosa et al 2016;Rocha et al 2018;Lima et al 2018Lima et al , 2020Sampaio et al 2019a) or description of new species (Loiola 2013;Souza et al 2016;Sampaio et al 2016Sampaio et al , 2019bRibeiro et al 2017).…”

This study presents the floristic-taxonomic treatment of Passifloraceae s.s. from the state of Ceará. Identifications were based on the analysis of collections deposited in national herbaria and photos of international herbarium collections, including types specimens, specialized bibliography and samples collected in the field. The family is represented in Ceará by 18 taxa of Passiflora, of which three are new records for the state: P. capsularis, P. kermesina and P. morifolia. Ten species were registered in Conservation Units in Ceará. The species occur in various types of vegetaion, but prefer more humid environments. Identification key, comments, images and distribution maps of the species are provided.

“…Most studies related to Malpighiales undertaken in Brazil have focused on their taxonomy and/or floristic surveys of different families, especially of Euphorbiaceae (Secco et al 2012), Malpighiaceae (Almeida et al 2018), Hypericaceae (Marinho et al 2016;Martins et al 2017;Martins & Shimizu 2018), and Passifloraceae (Costa et al 2015;Costa & Melo 2016). Recent studies of Malpighiales for the Flora of the State of Ceará have focused on Erythroxylaceae (Cordeiro & Loiola 2018), Turneraceae (Rocha et al 2018), Phyllanthaceae (Lima et al 2020), Salicaceae (Nepomuceno et al 2021), and Passifloraceae (Souza et al 2021).…”

Flora of Ceará State, Brazil: Caryocaraceae, Hypericaceae, and Rhizophoraceae

We examined the diversity and distribution of Caryocaraceae, Hypericaceae, and Rhizophoraceae in Ceará State, Brazil. Floristic treatments were carried out based on comparative analyses of the morphological characters of specimens from several Brazilian herbaria (ALCB, EAC, HCDAL, HST, HUEFS, HVASF, IAN, MBM, MOSS, SP, UEC and UFMT), the scientific literature, and photographs of type collections. Each family is represented here by a single species. Caryocar coriaceum occurs predominantly in the southern portion of Ceará State in typical open (cerrado) and forested savannas (cerradão). Vismia guianensis is widely distributed and occurs in several vegetation types, but mainly ombrophilous forests and savannas. Rhizophora mangle has a narrow distribution range, being recorded in coastal vegetation with fluvial and/or lacustrine influences (mangrove swamps). All three species were recorded in designated Conservation Areas. An identification key for the species, morphological descriptions, commentaries on their conservation, habitats and phenologies, as well as photographs and illustrations are provided.
