The Brazilian forestry sector has expanded to the Cerrado biome regions, where the soils are highly acid, with a high exchangeable Al content and a general nutritional deficiency. Nevertheless, the levels of soil organic matter (SOM) under the forest plantings are generally high and may play an important role in the complexation of Al in the soil solution. The objective of this study was to evaluate the effect of the introduction of Acacia mangium in monospecific Eucalyptus spp. plantations on the soil C content and its effect on the soil Al availability. The study was conducted at four experimental sites in São Paulo and Minas Gerais States in Brazil. We evaluated three treatments: monospecific stands (pure) of Acacia mangium and Eucalyptus and a mixed stand (constituted by Acacia mangium and Eucalyptus in 1:1 proportion), with four replicates at each site. The soil total C and the Al content in the soil solution (Als), the exchangeable Al (Ale) and the organically complexed Al (Al-OM) were determined at the soil depths of 0?5 and 5?10 cm. The introduction of Acacia in Eucalyptus plantations (mixed stand) significantly increased the soil C content by approximately 10% only at one of four sites studied, which was probably because the land was used as pasture before the introduction of the forest plantation and the because of high N input in a Eucalyptus plantation. Despite little improvement in the soil C content and consequently in the Al complexed by the soil organic matter, the introduction of Acacia in the Eucalyptus stands increased the Al availability by approximately 13% due to the reduction in the soil pH.

The aims of this study were to evaluate the antihypertensive effects of the standardised methanolic extract of Carica papaya, its angiotensin converting enzyme inhibitory effects in vivo, its effect on the baroreflex and serum angiotensin converting enzyme activity, and its chemical composition. The chemical composition of the methanolic extract of C. papaya was evaluated by liquid chromatography-mass/mass and mass/mass spectrometry. The angiotensin converting enzyme inhibitory effect was evaluated in vivo by Ang I administration. The antihypertensive assay was performed in spontaneously hypertensive rats and Wistar rats that were treated with enalapril (10 mg/kg), the methanolic extract of C. papaya (100 mg/kg; twice a day), or vehicle for 30 days. The baroreflex was evaluated through the use of sodium nitroprusside and phenylephrine. Angiotensin converting enzyme activity was measured by ELISA, and cardiac hypertrophy was evaluated by morphometric analysis. The methanolic extract of C. papaya was standardised in ferulic acid (203.41 ± 0.02 µg/g), caffeic acid (172.60 ± 0.02 µg/g), gallic acid (145.70 ± 0.02 µg/g), and quercetin (47.11 ± 0.03 µg/g). The flavonoids quercetin, rutin, nicotiflorin, clitorin, and manghaslin were identified in a fraction of the extract. The methanolic extract of C. papaya elicited angiotensin converting enzyme inhibitory activity. The antihypertensive effects elicited by the methanolic extract of C. papaya were similar to those of enalapril, and the baroreflex sensitivity was normalised in treated spontaneously hypertensive rats. Plasma angiotensin converting enzyme activity and cardiac hypertrophy were also reduced to levels comparable to the enalapril-treated group. These results may be associated with the chemical composition of the methanolic extract of C. papaya, and are the first step into the development of a new phytotherapic product which could be used in the treatment of hypertension.
