“…Peaks 11, 12 and 15 exhibited similar molecular ion peaks at m/z 515 indicating that they are possibly isomers, tentatively identified as 1,5-di-O-caffeoylquinic acid, 3,5-di-O-caffeoylquinic acid and 4,5-di-O-caffeoylquinic acid based on comparison with previous reports (Schutz et al, 2004). Peaks 13 and 17 also showed the same molecular ion peak at m/z 601 and based on its MS/MS fragmentation with m/z 515, 395 and 353, these were tentatively assigned as isomers of 3,5-di-O-caffeoyl-4-malonylquinic acid (Lin and Harnly, 2010).…”

a b s t r a c tCentella asiatica ('Pegaga' = Malaysia) is well known plant that has been used as one of the ingredients in pharmaceutical and cosmetic industries. Using liquid chromatography with diode array and electrospray ionization/mass spectrometry (LC-DAD-ESI/MS) analysis, chemical profiling of three different Pegaga extracts (C. asiatica, H. bonariensis and H. sibthorpioides) revealed variations in their metabolite profile. Our findings showed that triterpenes of C. asiatica were characterized by the ursane-type triterpenes (madecassoside, asiaticoside, madecassic acid, and asiatic acid), while the two Hydrocotyle species consisted of oleanane-type triterpenes (barrigenol derivatives). Other variations are due to the difference in phenolic and flavonoid constituents. The three Pegaga extracts were also evaluated for their total phenolic content (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radicals, and xanthine oxidase inhibition (XOI) activities. The results showed that C. asiatica has the most potent antioxidant activity (TPC = 72.09 mg/100 g DW; DPPH = 72.99 g/ml; XOI = 87.68 g/ml) as compared to H. bonariensis (TPC = 28.55 mg/100 g DW; DPPH = 22.43 g/ml; XOI = 32.23 g/ml) and H. sibthorpioides (TPC = 56.23 mg/100 g DW; DPPH = 37.86 g/ml; XOI = 14.73. g/ml).

“…The molecular ion [M+H] + at m/z 535.1080 in the HRLC-MS of compound 5 confirmed the identity to be luteolin 7-O-β-(6''-malonyl) glucopyranoside. Luteolin 7-O-β-(6''-malonyl)glucopyranoside has been identified in terrestrial plants previously [27] [28], but this is the first time it has been reported in Z. marina. Malonylated flavone glucosides have just recently been reported to occur in marine environments [29].…”

In extracts of the seagrass Zostera marina, collected in coastal waters of West-Norway, fourteen different flavones and high amounts of rosmarinic acid were identified. Five of the flavones were found to be sulphated, among these were luteolin 7,3'-disulphate and chrysoeriol 7-sulphate structures previously not published with complete NMR assignments. Luteolin 7-O-β-(6''-malonyl) glucoside, and two other malonylated flavone compounds occurring in trace amounts, were identified for the first time in Z. marina. The sulphated flavones were fairly stable in slightly acidified (0.1% trifluoroacetic acid) extracts stored for months, however, under more acidic conditions (0.5% trifluoroacetic acid in the extracts) they were susceptible to undergo hydrolyses. When the solvents of purified fractions were removed by rotary evaporation, the sulphated flavones quickly decomposed to their corresponding aglycones due to the increased acid concentrations.

FLAVONOID PROFILES AND EVALUATION OF ANTIOXIDANT POTENTIAL AND CYTOTOXICITY OF AMAZONIANBauhinia purpurea (Fabaceae). Plants of the Bauhinia species (Fabaceae) are used in the treatment of several infections and diseases, especially diabetes. In this paper, with an aim to contribute to the knowledge of the chemistry and therapeutic potential of the Amazonian species of the genus Bauhinia, flavonoid profiles in the leaves and branches of Bauhinia purpurea collected in Manaus and São Gabriel da Cachoeira/AM were analyzed by HPLC-DAD and ESIMS. Differences in the flavonoid profiles were detected along with the presence of rutin and isoquercitrin in the leaves collected in Manaus. All samples showed antioxidant activity, however, no cytotoxic activity against cell lines MDA-MB435 (breast), , and SF-295 (glioblastoma) could be detected.Keywords: Bauhinia purpurea; rutin; isoquercitrin. INTRODUÇÃOO gênero Bauhinia pertencente à família Fabaceae (subfamília: Cercideae) contém cerca de 300 espécies que são conhecidas popularmente no Brasil como pata-de-vaca pelo formato bilobado de suas folhas. 1 Elas são usadas na medicina tradicional em diversas partes do mundo por suas propriedades analgésica, antidiabética, antiinflamatória, antimicrobiana, adstrigente, diurética no tratamento de inchaços e tumores estomacais, diarréia e úlcera. 2-5 O uso popular mais comumente relatado para esse gênero no Brasil está relacionado à atividade hipoglicemiante, com várias espécies usadas para esse fim, em especial Bauhinia forficata, que é amplamente comercializada em variadas formas farmacêuticas. 6,7 As espécies de Bauhinia contêm diversas substâncias, como flavonoides livres e glicosilados, terpenoides, esteroides, ácidos fenólicos e alcaloides. 6-9 De espécimes asiáticos de B. purpurea foram isolados além de flavonoides, como kaempferol-3-galactosídio, isoquercitrina, rutina e astragalina, compostos raros da classe oxepinos, bauhiniastatinas, alguns com atividade citotóxica. [10][11][12] De um modo geral, as propriedades terapêuticas das espécies, especialmente as atividades antioxidante e hipoglicemiante, têm sido correlacionadas à presença de compostos fenólicos, em especial de flavonoides glicosilados, como a kaempferitrina, vinculada à ação hipoglicemiante da espécie B. forficata. [13][14][15] O estudo da espécie B. purpurea frente à atividade antioxidante vem ganhando destaque no estudo do gênero, já que seus extratos têm exibido potencial intermediário ou equivalente aos padrões geralmente utilizados nos testes para esta atividade. As substâncias fenólicas, atribuídas como as principais responsáveis por essas atividades, tem sido investigadas por meios cromatográficos e espectrométricos, na busca para estabelecer um perfil cromatográfico dentro da espécie. [16][17][18][19] Na região amazônica, o uso de espécies desse gênero não é diferente, havendo relatos para o tratamento de diabetes nos estados do Acre, Amazonas e Pará. As espécies são encontradas em muitas feiras e comércios a céu aberto, especialmente folhas, para uso co...
