“…[ 25 ]. Aurantiamide acetate ( 4 ) has been isolated previously from Aspergillus penicilloides [ 26 ], two alga species ( Cystoseira corniculata [ 27 ] and Acanthospora specifera [ 28 ]), and several families of higher plants: Euphorbiaceae ( Euphorbia fischeriana [ 29 ] and Croton hieronymi [ 30 ]), Piperaceae ( Piper aurantiacum [ 31 , 32 ]), Leguminosae ( Medicago polymorpha [ 33 ] and Pongamia glabra [ 34 ]), Sterculiaceae ( Pterospermum heyneanum [ 35 ]), Morinagaceae ( Moringa oleifera [ 36 ]), and Rutaceae ( Zanthoxylum setulosum [ 37 ]).…”

“…These data and the measured specific rotation are consistent with those published for N -benzoyl- l -phenylalaninyl- N -benzoyl- l -phenylalaninate, also named asperphenamate. Compound 5 has been isolated previously from fungal species: Aspergillus flavipes [ 38 ], Anaphalis subumbellata [ 39 ], and the Penicillum species P. canadense [ 40 ], P. brevicompactum [ 41 ] and P. megasporum [ 42 ]; and several families of higher plants: Euphorbiaceae ( Croton hieronymi [ 30 ]), Bignognaceae ( Zeyhera digitalis [ 43 ]), Piperaceae ( Piper aurantiacum [ 32 ]), Leguminosaea ( Medicago polymorpha [ 33 ] and Piptadenia gonoacantha [ 44 ]), and Moraceae ( Artocarpus kemando [ 45 ]).…”

Phytochemical investigations on the stem bark and roots of the tropical shrub Clausena anisata led to the isolation and characterization three carbazole alkaloids: girinimbine, murrayamine-A and ekeberginine; two peptide derivatives: aurantiamide acetate and N-benzoyl-l-phenylalaninyl-N-benzoyl-l-phenylalaninate; and a mixture of two phytosterols: sitosterol and stigmasterol. The structures of these compounds were established by nuclear magnetic resonance (1H-NMR, 13C-NMR, COSY, HSQC, HMQC, HMBC and NOESY) spectroscopy and electrospray ionization mass spectrometry (MS).

“…Peptides from C. mollis and C. macrophyllum. DOI: 10.3109/13880209.2013.770536 different plant species from the Piperaceae (Banerji & Ray, 1981) and Moringaceae families (Sashidhara et al, 2009). In the Leguminosae family, compound 1 was only obtained from Mucuma cinerea (Demune et al, 2003), and compound 2 is currently being described for first time in this family.…”

Context: Cratylia mollis Martius ex Benth. and Cenostigma macrophyllum Tul. (Leguminosae) are both endemic Brazilian plants and they are used by the natives as medicinal plants, and the leaves of C. mollis are also employed as forage for cattle during the dry season of region. Objective: Isolation of the compounds responsible for the acetylcholinesterase (AChE) inhibition from the CHCl 3 active extract. Materials and methods: Two peptidic compounds were isolated by chromatographic techniques from the CHCl 3 extract of the leaves of C. mollis and C. macrophyllum. They were identified by spectrometric data analysis (MS and NMR) and they were subjected to AChE inhibition employing Ellman's test.

“…In the course of investigating the chemical constituents from the bark of M. igeum, a new meroditerpenoid, igeumone (1), was isolated along with other nineteen known compounds: b-sitosterol (2), b-daucosterol (3), vanillic acid, auranamide (5) [4], ethyl caffeate (6), lup-20 (29)-ene-3a,27b-diol (7) [5], eugenin (8), naringenin (9), syringalhyde, phlogacantholides B (11) [6], quercetin (12), paederoside (13), 2-hydroxy-3-hydroxymethyl-9,10-anthraquinone (14), 1-methoxy-3-hydroxy-2-carbonmethoxy-9,10-anthraquinone (15) [7], lucidin primeveroside (16) [8], nemoroside (17) [8], picroside (18) [9] and naringin (19). The known compounds were identified by comparing their spectral data with reported data or with those of authentic sample.…”
