Within the Americas, Australia and Indo-Malaysia, 46 species in Brazil and with only few species within the forest within the Savanna vegetation, napeadic and high altitude grassland (1, two). Several plants of this loved ones are employed in folk medicine for their nutritive assets and therapy of quite a few diseases (3, 4, 5). Brazil, in unique has employed many the species inside the remedy of gastrointestinal and respiratory problems too as infectious diseases (6, 7). Previous phytochemical analyses of some species have led to isolation of hydrocarbons, alcohols, steroids, terpenoids, ecdysteroids, flavonoids, saponins, amino acids, butacyanins,* Corresponding author: E-mail: oltados@yahooreducing sugar and ketoses (two, four, 7-13). In spite of some phytochemical and biological activity studies which happen to be performed on certain species on the Amaranthaceae family members, the genus Gomphrena nevertheless remains poorly studied. Gomphrena celosioides can be a sprawling herb, native to Brazil, Paraguay, Uraguay and Argentina but has spread throughout the whole of your tropical planet. Within a study by Botha and Gerritsma-Vander (14), Gomphrena celosioides root extract exhibited weak antibacterial activity, whilst extracts of other parts had been active on nervous autonomic program of rats with sympathetic and parasympathetic symptoms. In our prior biological evaluation of G. celosioides extracts, antimicrobial, anthelmintic and cytotoxic activities have been established and also, 3-(4-hydroxyphenyl) methylpropenoate was isolated (15, 16). Inside the present paper, the isolation and characterization of aurantiamide and its acetateDOSUMU O et al. / IJPR (2014), 13 (1): 143-Figure 1. Sub-structure of aurantiamide.form in the hexane extract of Gomphrena celosioides are reported and this really is the first report with the isolation of those compounds in the plant. Outcomes and Discussion The dried whole plants were extracted by Soxhlet with n-hexane and this resulted in flaky crystals floating on top rated on the solvent on cooling. The floating crystals were collected and washed numerous instances with n-hexane. The TLC on the dissolved crystals showed two spots which cause column chromatographic separation on silica gel with five chloroform in n-hexane (see Experimental). This resulted in isolation of aurantiamide and its acetate. Aurantiamide (1) C25H26O3N2 showed a pseudo molecular ion peak at 384.3057 as a consequence of loss of water molecule. Actual molecular mass (M+ 402.0239, calc. 402.1804). It’s a neutral compound with no characteristic UV absorption. Its IR spectra (KBr) showed the presence of amide carbonyl (3400 cm-1, 1650 and 1639 cm-1) and mono-substituted phenyl moieties (1570, 755 and 720 cm-1) (17).E260 The 1H NMR (CDCl3) showed the presence of those groups with ONH- signals at six.Merocyanin 540 61 (1H, d, J = 7.PMID:24318587 five Hz) and six.52 (1H, d, J = 7.five Hz). The methylene group signals had been amongst 2.90 and 3.45. The 15 aromatic protons inside a benzoyl (between 7.48 7.68) with 3H creating multiplet and 2H generating doublet of doublet with J = 7, 2 Hz; Two benzyl of five protons in each and every group displaying absorption at 7.20 and 7.39, br. One pair of your methylene protons aremagnetically equivalent when the other individuals weren’t as a consequence of exhibition of conformational rigidity imposed around the molecule by intramolecular hydrogen bonding of your methylene group (17). The diasterotopic methylene protons signal adjacent to hydroxyl was observed at 4.03 (1H, dd, J = 7.two, 6.4 Hz) and four.50(1H, dd, J = 8.29, 5.38 Hz) (sub-structure (a)). The signals at.
