“…Chemical investigation of seeds of C. lineatifolia led to the isolation and identification of β-triketone type compounds, named champanones. 7 Studies of the leaves in this Campomanesia species identified quercetin, myricetin and rutin by HPLC. 8 In this way, the present paper describes the anti-M. tuberculosis activity of extracts, fractions and pure substances from Campomanesia adamantium fruits and the identification and quantification of flavanones and chalcones in these fractions, as well as their action against M. tuberculosis in vitro.…”

Recebido em 1/7/08; aceito em 19/12/08; publicado na web em 11/5/09The anti-Mycobacterium tuberculosis activity of Campomanesia adamantium fruits extracts were evaluated. Six compounds, identified as flavanones and chalcones were quantified by HPLC-DAD-UV. Promising antitubercular activity was observed with ethyl acetate extract (MIC 62.5 μg/mL) and their fractions (MIC values ranging from 39 to above 250 μg/mL). The better MIC result of 39 μg/mL was associated with two fractions that contain bigger amounts of 5,7-dihydroxy-6, 8-di-C-methylflavanone and 2',4'-dihydroxy-3',5'-dimethyl-6'-methoxychalcone. These compounds exhibited MICs >250 and 62.5 μg/mL, respectively, while their mixtures showed values ranging from 62.5 to 7.8 μg/mL, demonstrating a synergism between them.

“…La champa (Campomanesia lineatifolia R. & P., familia Myrtaceae [BONILLA et al 2005]), es una especie frutal cultivada en la región de Lengupá Boyacá-Colombia. Crece a temperaturas de 22 a 30ºC, con precipitaciones superiores a 1.500 mm anuales y necesita suelos de texturas francas a arcillosas.…”

“…Bonilla et al (2005) y Osorio et al (2006) han hecho aportes importantes sobre los compuestos extraídos de la semilla, los cuales tiene actividad antimicrobial y al parecer contribuyen a expresar los aromas y sabores característicos de la champa en todos los estadios de crecimiento del fruto. Balaguera-López et al (2009) avanzaron sobre el crecimiento y el desarrollo del fruto, y encontraron que desde la floración hasta la cosecha el fruto tardó 160 días, también observaron que la acumulación de masa fresca y seca siguió una curva sigmoidal simple, con una fase de lento crecimiento al inicio, seguida de una fase de rápida acumulación de masa que precede a la fase de maduración del fruto.…”

RESUMEN -La champa es una especie de la familia Myrtaceae cuyo fruto es muy apetecido por los consumidores, debido a su exquisito sabor y aroma. El objetivo de esta investigación fue realizar el estudio de algunos cambios bioquímicos durante el crecimiento y hasta la cosecha del fruto de champa, en el municipio de Miraflores, Boyacá-Colombia. Se marcaron flores de 30 árboles seleccionados al azar. Se hicieron cinco muestreos desde el día 26 después de la floración hasta la cosecha. Se llevó registro de la temperatura para calcular la acumulación de grados calor día (GDC). En el período de floración a cosecha del fruto (145 días) se acumularon 1489,1 GDC. Previo a la cosecha los azúcares aumentaron y los ácidos disminuyeron, pero su concentración fue elevada. Se detectó sacarosa (mayor concentración), fructosa y glucosa, ácidos cítrico (predominante en la cosecha), succínico, málico y oxálico. La actividad poligalacturonasa inició desde los 582,06 GDC y aumentó hasta la cosecha. La tasa respiratoria fue alta al inicio y disminuyó hasta los 1422,8 GDC, punto que coincide con la madurez fisiológica, en este momento también se detectó producción de etileno. Los frutos de champa presentaron alta acidez y un representativo contenido de azúcares que determinan su sabor característico. Términos para indexación: azúcares, ácidos orgánicos, actividad poligalacturonasa, respiración, etileno. BIOCHEMICAL CHANGES DURING GROWTH AND UNTIL HARVEST OF CHAMPA (Campomanesia lineatifolia R. & P. MYRTACEAE family) FRUITABSTRACT -The champa is a species belonging to the Myrtaceae family which fruit is very desired by consumers due to its exquisite flavor and aroma. The objective of this research was to study some biochemical changes during growth and until harvest of champa fruits in the municipality of Miraflores, Boyacá-Colombia. Flowers of 30 selected trees were marked randomly. Five samplings were performed from day 26 after flowering until harvest. Temperature was recorded to calculate degree days (DD). In the period from flowering to fruit harvest (145 days) accumulated 1489.1 DD. Prior to harvest sugars increased and acids decreased but their concentration was high. Sucrose (highest concentration), fructose, glucose, and citric (predominant at harvest), succinic, malic and oxalic acids were detected. Polygalacturonase activity started from 582.06 DD and increased until harvest. The respiratory rate was high at the beginning and decreased to 1422.8 DD, a point that coincides with the physiological maturity, at this moment ethylene production was also detected. The fruits presented high acidity and a representative sugar content which determine its characteristic flavor.

“…Desmosdumotin C (1) was previously isolated from the roots of Desmos dumosus [3] and Campomanesia lineatifoli 4 and it was isolated for the first time from Mitrella kentii. Desmosdumotin C (1) was a novel chalcone and it structure has been established by X-ray crystallography together with 1D and 2D NMR spectroscopy.…”

Mitrella kentii which belongs to the Annonaceae family is a tree-climbing liana found in the Malaysian Peninsula, Islands of Sumatra, Borneo, and New Guinea. This species was studied in 1972 for their alkaloids, 1997 and 2012 for their non-alkaloid constituents. In this study, chalcones, Desmosdumotin C (1) and their tautomer, 2-cinnamoyl-3-hydroxy-5-methoxy-4,6,6-trimethylcyclohexa-2,4-dienone (2), flavanone, 7-hydroxy-5,6-dimethoxy-2-phenylchroman-4-one (3), oxoaporphine alkaloids, Liriodenine (4) and Atherospermidine (5) and also terpenoid, -Sitostenone (6) have been isolated from this species. All these compounds were isolated for the first time from Mitrella kentii except Liriodenine (4). The isolated compounds were elucidated using spectroscopic techniques such as UV, IR,1D and 2D NMR and mass spectroscopy and by comparison their spectral data with those previously reported in the literatures. Desmosdumotin C (1) showed the anti-ulcer activity.
