| ABSTRACT Mouriri guianensis is a Brazilian endemic plant species distributed throughout the Amazon forest, Caatinga, Mata Atlântica and Cerrado domains, extending northward into Venezuela. The aim of this study was to describe the flowering phenology, floral biology and visitors associated with M. guianensis, highlighting the crepuscular bee species Megalopta amoena. Mouriri guianensis flowers from September to March. The flowering, the details of floral biology and the activities of floral visitors were observed for ten individual plants in December 2013, January-March 2014, September-December 2014 and January-March 2015. The flowering peaks occurred in December 2013 and in November-December 2014. Bees were collected in January and February 2015. A total... |

| ABSTRACT The Amazon forest is rich in plant species diversity, among them,Piranhea trifoliata stands out, which is popularly known as piranheira, because their fruits are eaten by fish. Their barks are used as bath composition on uterus inflammation and as tea in malaria treatment. This study aimed to fractionate the dichloromethane and dichloromethane phase from methanolic extract of leaves of Piranhea trifoliata. The leaves were dried, grounded and extracted with dichloromethane, methanol and water. The methanol extract was partitioned with dichloromethane and ethyl acetate. The chromatographic fractionation yielded six pentacyclic triterpenoids: friedelan-3-one, 28-hydroxy-friedelan-3-one, 30-hydroxy-friedelan-3-one, lupeol, α- and β-amyrin mixture,... |
