Determination of flavonoids in stamen, gynoecium, and petals of Magnolia grandiflora L. and their associated antioxidant and hepatoprotection activities

Chromatographic analysis of flavonoids in ethyl acetate fractions of the stamen, gynoecium, and petal of Magnolia grandiflora L. by HPLC-PDA-MS/MS-ESI in the negative ionization mode was performed in this study. The results revealed the presence of eight flavonoids: apigenin 8-C-glucoside, luteolin 8-C-glucoside, quercetin 3-O-rutinoside, quercetin 3-O-galactoside, quercetin, 3-O-glucoside, kaempferol 3-O-rutinoside, isorhamnetin 3-O-glucoside, and isorhamnetin. Their quantification revealed that luteolin 8-C-glucoside is the major flavonoid and that the total phenolic content is concentrated primarily in the stamen. The antioxidant and hepatoprotective effects of ethanolic extract of the flower organs were evaluated against hepatotoxicity induced by CCl4, compared with the effects of silymarin.

Utilização de parâmetros morfoanatômicos na análise da fitotoxidez do flúor em folhas de Magnolia ovata (A. St.-Hil.) Spreng. (Magnoliaceae)

Com os objetivos de avaliar o grau de suscetibilidade e caracterizar as injúrias na morfoanatomia de folhas de Magnolia ovata, mudas foram submetidas à chuva simulada com flúor (10 µg.ml-1 de F-) por 10 dias consecutivos. No tratamento controle, utilizou-se apenas água deionizada. Folhas foram coletadas para quantificação de flúor na matéria seca e fixadas para análises em microscopia de luz e eletrônica de varredura. As folhas apicais apresentaram pequena porcentagem de necroses intervenais e marginais em uma ou ambas as faces e maior acúmulo de flúor, em relação ao controle, quando comparadas com as folhas da porção basal. A análise micromorfológica das folhas aparentemente sadias indicou alterações nas paredes periclinais externas da epiderme e formação de concavidades, além de cristas estomáticas danificadas, erosão de ceras epicuticulares e presença de esporos e hifas de fungos. A caracterização estrutural das injúrias evidenciou retração de protoplasto das células epidérmicas, colapso das células do mesofilo e da epiderme e acúmulo de compostos fenólicos em células das regiões necrosadas. As alterações micromorfológicas das folhas ocorreram antes que sintomas fossem observados, o que comprova a importância da micromorfologia na diagnose precoce da injúria. As plantas de M. ovata apresentaram poucos sintomas visuais em resposta ao flúor, entretanto as alterações morfoanatômicas indicam que essa espécie possui potencial para ser utilizada como bioindicadora.

Changes in gene expression during drying and imbibition of desiccation sensitive Magnolia ovata (A. St.-Hil.) spreng. seeds

Seeds of Magnolia ovata were dried to different water contents to assess the viability and transcript abundance of genes related to seed development, cell cycle, cytoskeleton and desiccation tolerance.The expression of development, cell cycle and cytoskeleton relative genes (ABI3, CDC2-like and ACT2) alone could not explain the germination behaviour of M. ovata seeds in relation to drying damage. Irrespective of their initial water content, the seeds performed in the same way during the initial period of germination and the deleterious effects of desiccation only occurred in later stages. Expression of PKABA1, sHSP17.5 and 2-Cys-PRX did not show a relationship with desiccation. However, the expression patterns of PKABA1 and sHSP17.5 suggested the participation of these genes in protective mechanisms during the imbibition of M. ovata seeds.

Conservação de sementes de Magnolia ovata St. Hil

A pesquisa foi regularizada com o objetivo de estudar a influência do teor de água da semente e da temperatura de armazenamento sobre a conservação das sementes de Magnolia ovata (Magnoliaceae), uma árvore nativa brasileira. Para tanto, sementes recém colhidas com 23,5% de água foram submetidas à secagem para a obtenção de sementes com os teores de água de 17,4%, 10,9% e 7,1%. Em seguida, as sementes foram acondicionadas em sacos de polietileno e armazenadas a 15ºC e a 20ºC. As sementes foram armazenadas por 180 dias e avaliadas mensalmente quanto ao teor de água, à emergência, ao índice e à velocidade de emergência da plântula e ao comprimento e à massa da matéria seca da plântula. A conservação das sementes de Magnolia ovata é favorecida pela secagem das sementes; as condições favoráveis para a conservação são sementes com 10,9% de água e 15ºC ou 20ºC de temperatura do ambiente de armazenamento.

Constituents of the Leaves of Magnolia ovata

Two new lignans, magnovatins A (1) and B (2), along with nine known compounds, were isolated from the leaves of Magnolia ovata. The known compounds were identified as acuminatin (3), licarin A (4), kadsurenin M, 4-O-demethylkadsurenin M, oleiferin A, oleiferin C, spathulenol, parthenolide, and 11,13-dehydrocompressanolide. In addition, compounds I and 2 yielded four new derivatives (1a, 1b, 2a, and 2b). The structures of the new compounds were established on the basis of spectrometric data evaluation. Free-radical scavenging and antimicrobial activities of the major compounds 1, 3, and 4 were investigated.

Antipyretic and anti-inflammatory properties of the ethanolic extract, dichloromethane fraction and costunolide from Magnolia ovata (Magnoliaceae)

Aim of the study: Magnolia ovata (A.St.-Hil.) Spreng (formerly Talauma ovata), known as ""pinha-do-brejo"" or ""baguacu"", is a large tree widely distributed in Brazil. Its trunk bark has been used in folk medicine against fever. However, no data have been published to support the antipyretic ethnopharmacological use. This study investigated the antipyretic and anti-inflammatory effects of the ethanolic extract (EEMO). dichloromethane fraction (DCM), and the isolated compound costunolide. Materials and methods: The antipyretic and anti-inflammatory activities were evaluated in experimental models of fever and inflammation in mice. Results: The oral administration of EEMO, DCM and costunolide inhibited carrageenan (Cg)-induced paw oedema (ID(50) 72.35 (38.64-135.46) mg/kg, 5.8 (2.41-14.04) mg/kg and 0.18 (0.12-0.27) mg/kg, respectively) and was effective in abolishing lipopolysaccharide (LPS)-induced fever (30 mg/kg, 4.5 mg/kg and 0.15 mg/kg, respectively). EEMO was also effective in reducing cell migration in the pleurisy model. Intraplantar injection of costunolide also reduced the paw oedema, myeloperoxidase and N-acetyl-glucosaminidase activity induced by Cg in mice. Conclusions: Collectively, these results show, for the first time, that extracts obtained from Magnolia ovata possess antipyretic and anti-inflammatory properties, and costunolide appears to be the compound responsible for these effects.

Effects of drying rate and storage time on Magnolia ovata Spreng. seed viability

Magnolia ovata seeds have been reported as desiccation sensitive. In order to test if the drying rate would affect the assessment of storage behaviour of these seeds, the effect of different drying rates and storage times on the viability was tested. Seeds were dried over activated silica gel (fast drying) or salt solutions for different periods (slow drying) and stored at -20°C. Partial drying transiently increased the final germination and the germination speed index, but further drying resulted in reduction of these parameters. Drying rate affected the final germination and vigour. Seeds that were slow-dried to 0.10 g H 2O ̇ g -1 dw retained high viability when compared with seeds desiccated to the same water content level by the fast drying method, although their vigour was reduced. Only slow-dried seeds could be stored at -20°C for 90 d without reduction of viability. These data suggested that the storage behaviour of seeds of M. ovata seeds should be classified as intermediate.

Essential Oil and other Constituents from Magnolia ovata Fruit

The volatile and non-volatile constituents of the unripe fruits of Magnolia ovata (A. St.-Hil.) Spreng. (Magnoliaceae) were studied. The essential oils were obtained by hydrodistillation of the fruit of two plant populations (A and B) and analyzed by GC/FID and GC/MS. The oil of sample A was rich in sesquiterpenes, mainly spathulenol (19.3%), while the oil of sample B showed a predominance of aliphatic compounds, mainly hexadecanoic acid (52.0%). Extracts of the dried fruit contained fourteen known compounds including nine lignoids (magnovatin A, magnovatin B, acuminatin, licarin A, oleiferin A, oleiferin C, kadsurenin M, 4-O-demethylkadsurenim M and 7-epi-virolin), two sesquiterpene lactones (parthenolide and michelenolide) and three alkaloids (lysicamine, lanuginosine and O-methylmoschatoline). Michelenolide, 7-epi-virolin and lisycamine are reported for the first time in the species, while the remaining compounds have already been reported in the leaves and/or trunk bark of Magnolia ovata. Acetylation of oleiferin A yielded a new compound, acetyl oleiferin A, whose NMR data and that of michelenolide are furnished.

Impact of consciousness raising and social liberation on readiness to engage in regular physical activity among adults in Magnolia Park/Lawndale-Wayside, Houston, TX

According to the transtheoretical model, consciousness raising and social liberation are processes used to help individuals progress through the stages of change for a given behavior. This study assessed the impact of these two processes on readiness to engage in regular physical activity among a convenience sample of 35 adults in the Magnolia Park/Lawndale-Wayside area of Houston, TX. The duration of the study was approximately 4 weeks. All pre/post-test data were collected via self-administered surveys available in English or Spanish. Baseline data were used to determine the culturally relevant content of a one-dose intervention consisting of a presentation and dissemination of educational materials as well as a list of local physical activity opportunities. Although the intervention did not improve progression through the stages of change, significant increases were evident among 5 out of 6 processes of change. Based on these results and qualitative data, this study recommended that the Houston Parks and Recreation Department incorporate cultural competency into the design and publication of materials and revise the schedule of available programs (i.e.: increase the number of walking programs) in order to reflect the physical activity preferences of Magnolia Park/Lawndale-Wayside residents.^
