Essential oils from leaves, ripe and unripe fruits of Schinus terebinthifolius growing in Brazil were investigated. Oil content from either ripe or unripe fruits was similar (4.65% and 3.98%, respectively). Sesquiterpenes (from 78.0% to 90.4%) dominated the oil content of both leaves and unripe fruit. The essential oils were tested in vitro for their allelopathic activity on germination and radicle growth of Lactuca sativa and Cucumis sativus at 1,000 and 10,000 µg mL-1concentrations. The three samples tested were more active in inhibiting the radicle growth for L. sativa (88.6-92.4%) than for C. sativus (50.5-84.5%) at 10,000 µg mL-1 concentration.

O estudo químico das cascas de Ochroma lagopus Swartz levou ao isolamento e ou, identificação de uma mistura de ácidos graxos e triacilglicerídeos, de b-sitosterol (1), estigmasterol (2), daucosterol (3), estigmasterol-3-O-b-D-glicosídeo (4) e manitol (5).

Phytochemical investigation of the bark from Ochroma lagopus Swartz led to the isolation and or identification of a mixture of fatty acids and triacylglycerides, sitosterol (1), stigmasterol (2), daucosterol (3), stigmasterol-3-O-b-D-glycoside and mannitol (5).

Os flavonóides kaempherol, genisteína, naringenina, quercetina, morina, rutina, e quercitrina isolados do cultivar de soja UFV-5’ foram testados como inibidores de aldose redutase. Os melhores resultados foram obtidos usando morina e quercitrina.

The flavonoids kaempherol, genistein, naringenin, quercetin, morin, rutin and quercitrin isolated from UFV-5’soybean’s cultivars were tested as inhibitors of aldose reductase. The best results were obtained by using morin and quercitrin.
