Trends of Specialization in Pollen of Flacourtiaceae with Comparative Observations of Cochlospermaceae and Bixaceae [PDF]
Grana, 1975 Pollen from 17 genera of Flacourtiaceae was examined by SEM and TEM; twelve of them represented the primitive tribes Berberidopsideae and Oncobeae.

Epidermal structure, organographic distribution, structure and ontogeny of stomata in Bixaceae
Feddes Repertorium, 1989SummaryThe epidermal structure, organographic distribution, structure and ontogeny of stomatal complex in the family Bixaceae are illustrated and described. This family is represented by a single genus Bixa. The organs investigated are the leaves, stems, petioles, fruits and peduncles. The leaves are amphistomatic.

Phytochemistry, 1975
Abstract Three new flavone bisulphates have been found in the leaves of Bixa orellana . They have been identified as the 7-bisulphates of apigenin and luteolin and the 8-bisulphate of hypolaetin; the identities of the first two have been confirmed by synthesis.

Ontogenesis and variation of wood ‘parenchymatization’ in Cochlospermum vitifolium (Bixaceae)
IAWA JournalSummary Axial parenchyma proliferation (non-lignified parenchyma) in wood has been characterized for only a few species. In the present study, we characterized the proliferation, ontogeny, and seasonal variation of wood axial parenchyma in Cochlospermum vitifolium (Bixaceae). This study included material from natural populations from different sites in

Environmental Science and Pollution Research
Fluorine (F) is a toxic element for plants and can cause damage even at low concentrations. Brazil has several anthropogenic sources of F; however, relatively few native species have been studied. Thus, the objective of this study was to evaluate the responses promoted by F in Bixa orellana, a species native to South America and economically important ...

The Protective Function of Ants Visiting the Extrafloral Nectaries of Bixa Orellana (Bixaceae)
The Journal of Ecology, 1977Observations have been made on the nectar flow rates of the extrafloral nectaries on the pedicels of a number of individuals of the shrub Bixa orellana, growing in Costa Rica, and on the ant activities on the same plants. Damage to the flower buds by insects just prior to flower-opening can result in high abortion rates.

AbstractBACKGROUNDα‐Amylase (α‐AMY) and α‐glucosidase (α‐GLU) inhibitors are important for controlling postprandial hyperglycemia (PHG). Bixa orellana (annatto) reported inhibitory activity against these enzymes because of its bioactive compound content.
