“…All purified products were analyzed by 1 H and 13 C-NMR spectra and then compared with literature values. Accordingly, lignans 1 – 11 were characterized and identified as asarinin ( 1 ) [ 35 ], fargesin ( 2 ) [ 31 ], horsfieldin ( 3 ) [ 36 ], eudesmin ( 4 ) [ 37 ], planispine A ( 5 ) [ 36 ], planispine B ( 6 ) [ 38 ], yangambin ( 7 ) [ 39 ], acuminatolide ( 8 ) [ 40 ], salicifoliol ( 9 ) [ 41 ], magnolone ( 10 ) [ 42 ], and magnone A ( 11 ) [ 43 ].…”

The speciation of a methanolic extract of Zanthoxylum armatum stem bark has enabled the isolation and characterization of 11 known lignans. Among them, five compounds (6, 8–11) are reported in this plant for the first time. All of the chemical structures were elucidated on the basis of NMR spectral analysis. Additionally, their antifeedant activities against Tribolium castaneum were evaluated scientifically. Among them, asarinin (1), with an EC50 of 25.64 ppm, exhibited a much stronger antifeedant activity than the positive control, toosendanin (EC50 = 71.69 ppm). Moreover, fargesin (2), horsfieldin (3), and magnolone (10), with EC50 values of 63.24, 68.39, and 78.37 ppm, showed almost the same antifeedant activity as the positive control. From the perspective of structure-effectiveness relationship, compounds with the chemical group of methylenedioxy exhibited higher antifeedant activities and have potential to be developed into novel antifeedants or potential lead compounds to protect food and crops in storage.

“…Radical scavenging activities of plant extracts were determined through spectrophotometry using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging radical assay [19]. The radical scavenging ability was calculated by the formula, % I = [(AbsB − AbsA)/AbsB] × 100, and the IC 50 was determined from the linear decrease in the inhibition percentage.…”

Betulinic, ursolic and oleanolic acids isolated from the aerial parts of Eriope blanchetii (Lamiaceae) were subjected to different esterification reactions, yielding 12 C-3 position ester derivatives. All compounds were identified using spectroscopic techniques, such as IR, 1H-NMR and MS. The derivatives were further investigated for their antioxidant level, Artemia salina lethality and antimicrobial activity.

“…O efeito antiproliferativo frente a células tumorais de carcinoma hepatocelular (HepG2) com valor de CI50 de 8,6 µM também foi observado para o diplomeroterpenoide A (192), o qual foi isolado das raízes de M. invisa. 28,29,31 Das raízes de M. ophthalmocentra isolaram-se a Nmetiltriptamina (53) e N,N-dimetiltriptamina (54), que foram ativas (++) como alucinógenos, sendo que a substância 54 foi ainda ativa na propriedade antidepressiva. 32,33 Com isso, confirma-se a ação de plantas do gênero Mimosa L. sobre o SNC devido à presença de alcaloides.…”

The Mimosa Linnaeus genus (Fabaceae), comprises about 540 species distributed mainly in the Neotropical region, predominantly in the South America and Mexico. Mimosa L. species are ubiquitous in the several biomes due to their great environmental adaptation abilities. The present review describes the compilation of the chemical aspects and the biological activities from the genus Mimosa L.. The chemical survey showed the biodiversity of metabolites, represented by 19 species and 199 substances, divided into alkaloids, isoprenoids, saponins, and phenolic compounds, with predominance of two flavonoid subclasses: flavones and flavonols. The evaluation of the extracts, fractions, and isolated substances from different botanical material of Mimosa L. species showed a high potential for antioxidant applications, due to the reactivity of phenolic compounds against free radicals. In addition, the presence of seven indole alkaloids justifies the use of Mimosa plants in mystic-religious ceremonies with hallucinogenic purposes. Therefore, the records of the natural products and biological activities are important accesses to the knowledge of the biodiversity of Mimosa L. species.
