“…The knowledge of these structural features, which includes the molecular mass, together with review articles for the aporphinoid alkaloids class (Guinaudeau et al ., , , , , ), pointed to the alkaloids glaucine and norglaucine, both previously reported in the Annonaceae family. The comparison of the NMR data for majority compound 2a with data from the literature (Zanin and Lordello, ; Chiu et al, ) allowed the identification of the aporphine alkaloid glaucine, being the identified as norglaucine as a logical consequence of the MS data.…”

Aiming to verify the insecticidal potential of 16 native plants from the Araripe National Forest (ANFO) on L3 Aedes aegypti larvae in laboratory conditions, were researches performed in controlled conditions of temperature, air relative humidity and photophase, in a type B.O.D. climatized chamber, executed in period from August/2016 to May/2017. The adopted experimental design was completely randomized, represented by ethanolic extracts obtained from 16 native plants, besides the witness without application and with pyriproxyfen as chemical insecticide, conducted with four replicates in each plant extract. The application of the extracts was performed only once, and at 24, 48 and 72 hours, after the infestation, was determined the effects of the extracts on larval mortality. The extracts of Amargoso, oil’tree, Lacre, Cajui, Louro smelling, Field Rosemary, Murici truthful, Janaguba and laranjinha provoke mortality above of 90% to the larvae of Aedes aegypti after three days of exposure, in the dose of 50 mL of the extracts. After 24 hours of exposure, the ethanolic extracts from barks and leaves of Field Rosemary and of laranjinha killed all the larvae. On the other hand, the extracts with higher larvicide potential were evaluated at different doses (i.e., 12.5, 25, and 50 mL/L) in a 9 × 3 factorial scheme, with four replicates. The ethanolic extract of the leaves of Louro smelling is the most efficient, because in any dosage it eliminates all the larvae of Aedes aegypti, thus demonstrating to be an excellent vegetable larvicide in the control of this vector after three days of exposure, whereas the bark extract of the oil’tree is the least effective. The alkaloids and flavonoids are present in the leaves of the Louro smelling.

“…Rosewood (Aniba rosaeodora Ducke, Lauraceae) is a commercially valuable tree, whose essential oil is in much demand industrially [1,2]. The species is, however, in danger of extinction [3][4][5] and cultivation in plantations is beginning to be seen as a financially-viable commercial option [6,7].…”

Rosewood (Aniba rosaeodora Ducke) is an endangered tree that produces essential oil of high commercial value. However, technical-scientific knowledge about cultivation is scarce and studies are needed to examine the management viability. The current study evaluated rosewood aboveground biomass management, measuring the export of nutrients resulting from harvesting and testing sustainable management models. The crown of 36 rosewood trees were pruned and 108 trees cut at 50 cm above the soil in two regions in Central Amazonia. Post-harvest performance of sprouting shoots was evaluated and after, sprouting shoots were pruned so that the development of two, three and all shoots was permitted. Nutrient stock estimation was calculated as the product of mass and nutrient concentration, which allowed nutritional replacement to be estimated. The pruning facilitates regrowth by 40.11% of the initial mass while by cut regrow 1.45%. Chemical attributes of regrowth biomass differed significantly prior to management and regrowth had a significant correlation with the reserves in root tissues and with the pre -management status of the individual tree. Driving sprouts resulted in significantly larger growth increments and may provide a form of management that can viably be adopted. Biomass sequential management resulted in high nutrient exports and the amount of fertilizer needed for replenishment depended on the intensity and frequency of cropping. Compared with the cut of the tree, pruning the canopy reduces fertilizers that are required to replenish amount by 44%, decreasing to 26.37% in the second rotation. The generated knowledge contributes to this silvicultural practice as it becomes ecologically and economically viable.
